Why Would a Baby Boomer Need an iPod?

Why Would a Baby Boomer Need an iPod? By Debra Conrad
If you're a Baby Boomer, you'll know if you are one, your life is full. Busy is a word we use often. Your lives are busy with family, work, chores and errands. Frantic, might be a better description. It's called life in the fast lane.
Baby Boomers want to have it all, and get it all done now, if not sooner. Have you taken notice of what you are doing? Why you are so busy? Are you sitting in the doctor's waiting room? Are you stuck in traffic? Do you spend time on your lunch hour doing busy work for your boss?
With a new iPod, you can fill those lost minutes and hours with guilt free time spent on yourself. The New York Times can be read to you each day.You can listen to the latest bestseller listed in Oprah's book club. Music without commercials is available anytime. The latest podcasts are accessible anywhere.
Baby Boomers might think that the iPod technology is too advanced or may only be for the teen scene. The concept, that Baby Boomers are slow to get with the times, can be pervasive. Portable Mp3 players are easy to use. If you have a computer and a high-speed connection, you will have your digital player ready in no time.
If you love to cook, why not listen to your favorite author's latest while waiting for the pasta water to boil? Have an inspirational podcast ready when you are stuck in traffic. Why not listen to your favorite tunes at work? Tons of options are available for you who can get past the technology paralysis.
If you wish you had more time to read, this is your answer. Do something for yourself, without feeling the guilt. You can cook dinner, clean up the dishes and get a load of laundry started, all while getting in another chapter of the newest mystery. You can charge up your Mp3 player every night, at the same time it is loading with the latest podcasts. This process only takes about an hour and then it's ready to go.
Do you have someone that is visually impaired in your life? An iPod would be a fantastic gift. The best would be one you loaded up with hours of books, music and podcasts. This would be a gift that would last a long time. How about loading it with more goodies every year? I paid a neighborhood teen to find tons of things online and then download them to my father-in-law's player. I plan to do the same for many years on his birthday. What a treat for for an active Baby Boomer!
Don't let this technology pass you by. You can do it!
Debra Conrad will help you learn about mp3 players, podcasts, audio download and tons more. A portable mp3 player is a cool little gadget popular with the teen croud, but has so many benifits for the baby boomer generation. If your interested in podcasts this site is perfect for understanding a new technology without using "geek speak".

Video Podcasting

Video Podcasting - Big Thing By Eddie Miller
Podcasting, a term coined formerly for the free downloading of audio segments onto Apple iPods, now is being expanded to include video as well. The new iPods that are video enabled are expected to bring in a flurry of video revolution and set off a whole new wave of media. Although currently radio shows are the most popular Podcasts, TV shows, humorous videos, and other forms of media are expected to become the new craze as the new iPod video-enabled units hit the shelves.
A rather interesting detail, however, in lies as to what sorts of video Podcasts are expected to be the most popular. Religious sermon videos are expected to be big, especially since they have a large audio Podcast following, as well as certain forms of audio shows that are expected to transfer to video as well. Another media that is expected to get big through video Podcasting is pornography. Although the initial quality that the new iPods can display is still under consideration, pornography is still expected to be a big Podcasting favorite when the new iPods become available.
What kind of new age are we getting ourselves into? Nobody really knows. But, needless to say, this new technology and the ability it brings to have almost limitless amounts of audio and video files at our fingertips 24/7 is definitely very intriguing. The leaps and bounds made by Apple and its iPod are only the beginning of future technological advancements involving little devices such as these. The future awaits.

Smart Apple iPod Tips and Techniques

Smart Apple iPod Tips and Techniques By Katherine Xie
Are you thinking of buying an Apple iPod? Or have you bought one?
Almost everyone and anyone that I know seems to have bought an iPod or at least is thinking of getting an ipod for themselves or their loved ones. The iPod is just so alluring! However, do you know what you should do after buying the iPod?

Most people don't. Yet, market analysts estimate that the average iPod owner spend as much as 30% of the original iPod price on additional accessories! That's a whopping US$60-US$90 on iPod accessories that each iPod owner will spend!

Many people are simply spending their money on the wrong accessories! In fact, many are going for fancy accessories such as car transceiver kit, wireless remote kit, speaker kit even without realizing what are the first accessories they should get.
Get the Basic iPod Accessory before getting the Fancy Stuff!
Do you, as a iPod user, faces these problems on a daily basis too?
* iPod Screen scratches
* Click wheel scratches
* Mirrored back scratches
* Messy iPod earphone cables
* iPod overheating when being charged while in a silicone or leather case

Despite the technical and cosmetic superiority of the Apple iPod, there remain some teething issues. Weak batteries is one. Being easily scratched is another. These problems immediately lower the resale or trade-in value of the iPod, if any? This may not seem important but if you are trading in your older iPod for a new one, this does matter. It also sucks to see scratches and marks on the beautiful iPod. In fact, microscopic scratches takes place everytime you take the iPod in and out of pocket!

Get a good-quality iPod case before ANYTHING ELSE!
There are numerous iPod accessories out there. Many accessories are fanciful, some are good but most do not fulfil the basic need of the iPod. You need to protect the iPod from getting scratches and accidental marks before anything else.
Before the iPod can serve you well, it must be able to take care of itself. So, before you even look further into getting your first iPod accessory or even if you have gotten numerous other accessories, make sure you first equip your iPod with either a good quality case or sleeve.
The most common iPod cases in use are:

Handphone sleeves converted to iPod sleeves
This is the most common as handphone sleeves are cheap and easily available. However, the mirrored back of the 3G and 4G ipod are easily scratched by theses sleeves as they run against the iPod. It is not recommended unless you have a budget problem.
iPod screen and wheel sticky protectors

There are transparent iPod screen and wheel sticky protector that are cut of the right size and stucked directly onto the iPod screen and wheel. However, there are various models in the market and some of the cheaper ones tend to curl and peel off after some use. If you are on a budget, a good quality screen and wheel protector is the minimum you should have.
iPod silicone skin

This is the most common iPod case around. It looks like a good casing choice but it is in fact one of the worst, especially if you have bought a cheap one.
These cheap silicone cases are being mass-produced in China with doubtful materials and design elements. Many of the cheap silicone skins in the market tear easily and pick up lint and dirt easily. They are also difficult to wash and maintain. I will not advise a silicone case unless they are made by some of the better and branded products from USA or Japan. A good model is found at: http://www.smart-ipod-ideas.com
iPod Leather case
The iPod leather case is one of the most popular case. However, do not get the Apple branded one if possible as it tears to scratched the mirror back and it does not have a covering flap. Get one of the leather cases from the many in the market. Check the stitching on the leather case before buying one as some of the mass-manufactured ones may have poor workmanship.
Water and shock resistant cases

There is an increasing demand for such cases as more and more people bring their iPod for hiking, cycling, trekking, fishing and beach trips. There are various good brands in the market. However, note that whatever the advertisement may say, at best, the case can only be water resistant and not water proof which is two different things all together. A water resistant case can only take splashes and short immersion in water and certainly not something you can bring for swimming or diving trips!

A Technical Introduction to Audio Cables

A Technical Introduction to Audio Cables By Adam Blake

What is so important about cables anyway?

One of the most common questions asked by consumers faced with purchasing cables for their audio or home theater system is, “What is so important about cables anyway?” They can cost as much or more than some of the hardware in the system and to many it is difficult to understand why wire isn’t just wire.

To begin to understand how audio cables work, we have to start with the two fundamentally different types of audio cables you are likely to have in your system. The first type of cable is called an interconnect, which is used to connect various components together (such as a CD player to a receiver). The second type of cable is called the loudspeaker cable (this is the wire going from the receiver or amplifier to the speakers). It is important to realize that both types of cables are carrying the same information, just with different amounts of energy.

Interconnects carry a signal with very little energy. These cables only need just enough energy to convey the information from the source, for example a CD player, to the amplifier. The low energy requirement means that the signal in interconnects has very little current (usually in the range of thousandths of an amp).

Loudspeaker cables on the other hand, carry a large amount of energy. All of the energy required to move the speaker cones and make sound must come through the loudspeaker cables. Because of the high-energy requirement in these cables the current is relatively high (currents can reach 10 amps or more).

The very basic reason why audio cables are important is because they change the signal going through them. There are two different, fundamental ways that an audio cable can change the signal. The cable itself can change the signal, or the cable can allow outside sources of energy to change the signal.

In order to understand how these two situations can occur, some basic background electrical knowledge is needed. Signals in all types of wires are conveyed by the combination of voltage and current. Every signal has some amount of voltage and some amount of current. The larger the difference in voltage between two places, say the beginning and the end of a cable, the larger the amount of current, and vice-versa. The direct analogy to voltage and current is the flow of water through a hose. The amount of water flowing through the hose is analogous to current. The water pressure in the hose is analogous to voltage. The higher the amount of water pressure, the more water will flow through the hose. The higher the amount of voltage, the more current will flow through the wire.

Every cable has a set of electrical properties that can be measured using standard electrical testing equipment. The three most basic properties are resistance, capacitance and inductance. While a detailed description of these three different electrical properties is outside the scope of this article, a basic description of the relevant effects of these three properties can be given.
- Resistance opposes current. The higher the resistance the greater the amount of energy that is removed from the current and turned into heat.
- Capacitance opposes changes in voltage. If a voltage is increasing, capacitance will cause the voltage to increase more slowly. If a voltage is decreasing, capacitance will cause the voltage to decrease more slowly.
- Inductance opposes changes in current. If current is increasing, inductance will cause the current to increase more slowly. If current is decreasing, inductance will causethe current to decrease more slowly.

The final piece of background knowledge that is needed for this article is what the audio signal looks like. If one were to take the speaker cover off a speaker to look at the speaker cone while music is playing, you would see that it is moving back and forth. In order to move the speaker cone back and forth, the electrical signal must push and then pull the cone in rapid and repeating fashion. This is accomplished by having an Alternating Current, or AC.

Alternating Current simply means that the voltage oscillates between positive and negative. Because the voltage drives the current, this means that the current also goes positive and negative. In other words, the current is going back and forth in the wire, just like the speaker cone. The subtle variations in how fast the voltage and current go back and forth creates the different sounds that we hear when listening to music.

How a cable itself affects the audio signal
Now, going back to the ways that the cable itself can change the signal going through it, let’s consider both types of cables separately.
As stated previously, interconnect cables carry a very small amount of current. Relative to the current the voltage is large. Because of that fact, capacitance is important, but inductance is relatively unimportant. As the voltage oscillates between being positive and negative, the capacitance slows the voltage changes down, and causes delays. This can cause audible distortion in the sound. Because interconnects have very little current, resistance is not much of a factor. Even an interconnect with extremely high resistance will only remove an infinitesimally small amount of energy.

The signal in loudspeaker cables is essentially the opposite of the signal in interconnects. Both cables have the same information, but in loudspeaker cables, the voltage is small and the current is large, relatively speaking. Because of the high current, both resistance and inductance are important in loudspeaker cables. The higher the resistance, the greater the amount of energy that will be absorbed by the cables. The resistance will not cause any distortion, but it will decrease the volume of the sound. The inductance on the other hand, can cause distortion. As the current oscillates between being positive and negative, the inductance slows the current changes down, and causes delays.

How a cable lets outside sources of energy affect the signal
As stated previously, the second fundamental way of altering a signal passing through an audio cable is to introduce outside sources of energy. This outside energy is typically termed “noise”. By definition, if any energy is absorbed by the signal, the signal has been distorted.
There are many potential sources of noise around audio cables. Some of the more common sources of noise, such as radio frequency waves, are familiar to most people. When wiring up a radio, frequently a consumer must attach an antenna. Antennae are intentionally designed to channel radio frequency energy into a stereo. Just like an antenna, it is entirely possible for an audio cable to pick up radio frequency energy. If you are not intending to listen to the radio, this is not a welcome effect.

Electronic components, electrical cords, sound waves, and even the sun, are all capable of creating noise. Electrical cords create electromagnetic fields around them that can transfer energy to a cable. Sound waves create mechanical vibrations that can be transformed into electrical energy that is added to an audio signal. Because there are so many different types of noise, there are many methods used to prevent a cable from picking up noise. Shielding, twisting of conductors, and mechanical damping are all common noise protection methods in cables.
While noise affects both interconnects and loudspeaker cables, generally the effects are far more significant in interconnects. This is because the signals in the interconnects have far less energy. Since most forms of noise are inherently low energy to begin with, this means that it is far easier for them to modify the low energy interconnect signals than the high-energy loudspeaker cable signals.

Macro vs. Micro
The parameters discussed so far have been primarily “macro” effects. These are for the most part the top-level parameters that effect cables. These parameters as well as others not discussed here also exist at a “micro” level. Taking capacitance as an example, a given cable will have an overall capacitance that can be measured. This overall capacitance is a “macro” level parameter. The same cable can also be analyzed as 1000 separate but connected pieces. Each piece will have a local capacitance. These local parameters are “micro” effects and can have their own impact on the signal separate from the “macro” effects.
The impact that the “micro” level parameters have on an audio signal is usually less than the impact of the “macro” level parameters. However, they do still make a difference in the signal transfer. The various ways that audio companies choose to either mitigate or ignore these “micro” level details is, in part, responsible for the vast array of different cable designs. From cryogenic treatments and precious metal wires, to fine silk insulation and fluid filled cable jackets; extreme cable designs abound.

Will I hear the difference?
The fact of the matter is that cables do alter the sound going through them, and that it is audible. You do not need to be an expert, or an audiophile, to hear the difference. To demonstrate this point, simply listen to your stereo. If you close your eyes, does it sound like the music is being played live right in front of you? This is what audiophiles strive for, and unless you have a very high-fidelity system, your answer to this question will most likely be no. You may have a hard time describing what exactly does not sound right about your system, but you know that it doesn’t sound like a live performance.
Of course, the reason why the music does not sound live cannot be blamed solely on the cables. The degradation of the sound occurs in every component of your system. However, the point here is that even a casual listener can detect the subtle distortions that can prevent music playback from sounding live. Improving the quality of your audio cables will improve the sound quality of your system.

It is fairly safe to say that no matter what cable you use, the modifications to the sound will be small. Audio cables will never cause a listener to hear a piano when a flute is being played. However, it is the small detail that makes all the difference between good and bad quality sound. That is why very strong opinions are formed about various cables.

As audio systems continue to improve in accuracy, listening to a “live” performance in your living room gets closer to reality. Cables are an enabling factor for advancements in audio reproduction and can play a remarkably important role in your system.

Review of Rio MP3 Players.

Review of Rio MP3 Players By Bradley James
Below you will find some useful information and comments about a few of the most popular MP3 players by Rio, including the Nitrus, Carbon, Cali, and Forge. None of these MP3 players are perfect, but each offers a unique set of strengths and weaknesses that should be taken into consideration before you purchase any one of them. Be sure to compare price, usability, and the overall performance of each.

Rio Carbon 5 GB MP3 Player
Manufacturers Description: The Rio Carbon is capable of holding up to 80 hours of MP3 (160 hours WMA) music, and with up to 20 hours of battery life on a single charge, music lovers need not worry about running out of juice.

Comments: Users tend to agree that this is one of the best mp3 players Rio has developed. It's really quite small and slim, and can actually fit in your pockets. 5GB of memory really doesn't sound like all that much any more, but I think most new user will find that that is plenty of space. The long battery is nice (20 compared with iPod's 12), and the interface is easy enough to work with. One little dissapointment is the inability to hit any buttons on the device when it is in its carrying case. Also, it does have some compatibility issues with Mac music programs like iTunes. If you really love Mac, you may want to consider iPod or Shuffle instead (this goes for all Rio products).
Price: $230

Rio Cali 128 MB Sport MP3 Player
Manufacturers Description: Wrapped in grippy, protective rubber, the Cali 128 is built to play hard. Solid-state electronics carry over 30 songs with no skips -- ever. Comfortable Sport Clip earphones, case with armband, and integrated stopwatch with lap timer make the Cali a functional sport accessory. 5-band adjustable equalizer gives more control over your sound than most players. Onboard FM tuner means you always have something to listen to. An empty expansion slot allows you to add up to 512 MB of additional SDTM or MMCTM memory. Simple menus and intuitive controls make for easy one-handed operation.
Features:
- 128 MB of memory plays back over 2 hours of MP3 or 4 hours of WMA music (over 30 MP3 or 60 WMA songs)*
- Expansion slot to add up to 512 MB additional memory using SD or MMC cards (sold separately)
- USB 1.1 connects to almost any computer
- Transfer content between multiple PCs
- 18-hour continuous playback using one Energizer AAA Battery
- 5-Band adjustable equalizer with pre-sets
Comments: Anyone considering buying this device should be aware of some odd functional issues that may be frustrating. First of all, when changing memory cards, many users have had to actually take out the batteries in order to get the device to recognize the new memory card (another note: some users have had problems getting the device to accept 3rd party memory cards). Also, it seems that the player may not be able to play regular mp3 formats you may have on your pc hard drive. Rio admits that these mp3 files need to be converted through their own software in order for them to work. These, and other odd quirks, undermine this particular player quite a bit. On the positive side, the device has good battery life, plays clear, crisp music, and has a good radio feature as well.
Price: $120

Rio Forge 512 MB Sport MP3 Player
Manufacturers Description: The Rio Forge series is our latest generation of flash based sport players. The Rio Forge was designed for people that like to play hard and use music to play even harder. The new design integrates the grippy, protective rubber from previous models with a new shiny stainless steel face plate for added durability. Up to 20 hours of battery life allows you hours of non-stop work out time. Comfortable Sport Clip earphones and a newly designed case with armband keep your player and music secure and accessible. Simple menus and intuitive controls make for easy one-handed operation. Stopwatch and Lap Timer make the Rio Forge the ultimate gym or running companion. Plus, the new FM record feature allows you to record radio content onto your player to listen to at a later time.
Features:
- Holds 16 hours worth of Music
- Storage capacity may be upgraded up to 1 GB
- Durable Stainless Steel Face
- 512 MB of storage
- Stopwatch feature for work-outs
- Up to 20 hours of battery life
Comments: This latest generation of sport mp3 players by Rio is perhaps the best so far. What we really liked about this device is the easy to use and intuitive user interface and clear LCD screen. The one downside is the 512mb upper limit in storage (although technically you can upgrade to 1GB), which is a little low compared with the market average. Even so, the features like the FM tuner and stop watch make this a really cool little sport mp3 player. It's about as durable and user friendly as they come, plus the battery life is friendly for those long work-outs. Thumbs up on this one.
Price: $180

Rio Nitrus 1.5 GB MP3 Jukebox
Manufacturers Description: The revolutionary Rio Nitrus packs 1.5 GB into a stealthy, razor-thin design. With the ability to carry over 375 songs, never before has this much capacity been offered on a player this small. Fast USB 2.0 connection loads the player quickly. Simple menus, thoughtful controls, and a clear display make navigation instinctive. A 5-band adjustable equalizer provides a custom listening experience. Quality components throughout yield a player without compromise.
Features:
- 1.5GB HDD plays back over 25 hours of MP3 or 50 hours of WMA music (over 375 MP3 or 750 WMA songs)
- USB 2.0 for fast transfers
- Transfer content between multiple PCs
- 16-hour continuous playback with the rechargeable LiIon battery
- 5-Band adjustable equalizer with pre-sets
Comments: This is an overall fairly solid mp3 player with a few design and engineering defects that should be mentioned. First, the buttons are not quite as easy to use, or as well laid out as some of Rio's other players. Specifically, the volume buttons are smaller and closer together than they should be. Another thing is problems with the battery life, some users getting significantly less time out of their batteries than they are supposed to. And you really can't expect to get the full 16 hours. Also, the scrolling feature doesn't seem to help much. On the plus side, the device is big enough in storage size (1.5GB), and small enough in physical size to appeal to alot of potential consumers. The sound is also quite good and just about every volume level.
Price: $175

Understanding Projector Screens: Be Careful, You May End Up With TOO Bright An Image!

Understanding Projector Screens: Be Careful, You May End Up With TOO Bright An Image! By Andrew Ghigo
Today's compact yet powerful front video projectors may leave you with a too bright an image to watch! This being especially so if you intend to watch a projected image in a darkened room – which after all, is most often the case with a home theater setup.
Defining ‘Screen Gain’

Prior to proceeding with our discussion, it is important that one has a full understanding of what the term ‘screen gain’ is all about.

It may sound strange that we talk about ‘gain’ when in reality a projector screen is nothing more than a passive device. Yet there is - it is all a question of how the screen surface distributes the reflected light.

Screen gain is a measurement of the reflectivity of the screen surface. It measures the ability of the screen to direct incident light back to the audience.

The gain number represents the ratio between incident light and reflected light. A flat matte white surface has a gain of approximately 1. A gray screen has a gain less than 1 and therefore, it attenuates incident light. Reflective screen surfaces have gains greater than 1; these projection screens direct more incident light back to the audience.

Gain is always measured in front and perpendicular to the screen at the point of maximum brightness; this represents peak screen gain and occurs at the zero viewing angle perpendicular to the screen surface.

For a screen with gain greater than one, the gain drops as one moves to the side and view the screen at an angle to the perpendicular drawn from the center of the screen. The angle at which screen gain falls to half the peak is referred to as ‘half gain viewing angle’. A person viewing the screen from this angle will see the image half as bright as the person seated at the center. The more one moves further away from the center, the dimmer the projected image will be.
The higher the peak screen gain, the narrower the supported viewing angle. This is the price one has to pay for a higher screen gain - the higher projector screen gain at the center is in fact achieved by directing more light towards the center viewing positions rather than allowing for a uniform reflected light over a wider angle of view.

Projected Image Brightness:
Matching the projection screen gain with the ambient light and the video projector output is essential if you want to ensure that you will end up with a correct level of projected image brightness.

This is an extremely important issue. Do not forget that a basic requirement for a great movie experience is a comfortable environment. This means that the time one spends watching a movie should be as comfortable as possible. Exposure to a bright projected image is uncomfortable on the eyes - even when this is for just a few minutes, least imagine when watching a two-hour movie.

A Tricky Matching Process!
Ambient Light Conditions, Image Brightness & Screen Gain
A projected image is at its best when viewed in total darkness - this helps take away any visual distractions - rendering it easier for the viewer to get deeper immersed into the movie action.
In the home, achieving a completely darkened room is almost impossible except in the case of the dedicated home theater setup. The amount of ambient light present has an impact on the resultant projected image contrast. This calls for the need to increase the image brightness to maintain the correct level of image contrast.

The tricky issue is to arrive at the correct level of image brightness for a pre-set level of ambient light. This in view that projected image brightness is a function not only of the projector output, but also of the screen gain, and image size.

The explanation that follows should help you get a better understanding of the relationship that exists between these three inter-related parameters.

Display Brightness and Screen Gain
The brightness output level of your projector is a measure of the projector output power in terms of light intensity. Please keep in mind however that the resultant projected image brightness is a different issue. Image brightness falls in proportion to the area of the projected image size - the bigger the projected image is, the dimmer it will look for a fixed level of projector brightness.

The projected image brightness - more specifically the Luminance level for a projected image, is a measure of the light reflected from the projector screen area. It is measured in foot-Lamberts, and is defined as:
ANSI-lumens of your projector divided by the square footage of Screen.
(Note that one foot-Lambert is equal to 1 ANSI lumen per square foot.)
To arrive at the actual level of light reflected from the screen surface, the above result must be multiplied by the projector screen gain.

A useful reference here is what has been defined as 'sufficient brightness' by the Society of Motion Pictures and Television Engineers, also known as SMPTE.

In standard 196M, the SMPTE determined sufficient brightness for showing motion pictures in a darkened room using a unity gain matte white projector screen, as 12 - 22 foot-Lamberts. In practice, the luminance target level is set to about 16 foot-Lamberts, while the average bright scene brightness level in a movie theater is typically 60% to 75% of this target value.
Display brightness is in itself an entirely subjective term; what’s more, it is all relative to the amount of ambient light falling on the screen surface.

The following rules of thumb would surely come to assistance in this respect:
The contrast ratio between the projected image and the ambient light level falling on the screen should be at least 5:1. This is necessary for the eye to perceive a real impression of brightness. If this contrast ratio is not achieved, the projected image will not be considered of adequate brightness level.

When viewing takes place under normal ambient light conditions, the luminance level should be close to 50 foot-Lamberts. This level of luminance is derived from the fact that SMPTE indicated a target level of image brightness for a CRT TV as 50 foot-Lamberts, this in view that a TV is normally viewed under normal ambient light. One may argue that TV is a totally different technology – this is true, but this target level for image brightness or luminance, still holds good for most circumstances.

How does all this translate in practical terms?
If one is viewing an image in typical very low ambient light conditions (say less than 2 foot-candles - equivalent to approximately 22 Lux), then the minimum required light level ‘illuminating’ the screen surface should be around 10 foot-candles to achieve sufficient image contrast.

For a matte white projector screen surface with a screen gain of one, this translates to a minimum of 10 foot-Lamberts in terms of light ‘reflected’ from the screen for image brightness. This is close to the SMPTE typical requirement for average luminance when viewing pictures in a darkened room.

Similarly, if viewing were to take place under normal ambient light room conditions (typically 10 foot-candles or 110 Lux), applying our first rule of thumb to achieve the required contrast level would result in a luminance level of 50 foot-Lamberts (approx. 540 Lux) for the same matte white projector screen surface. This is also in line with the target luminance level detailed in rule 2 for viewing under normal ambient light conditions.

Note:
Light illuminating a surface is measured in lux (Lx = lumens/m2), or foot-candles.Light reflected from an area (luminance) is measured in candelas/m2 (cd/m2) or foot-lamberts (fL).
Now, let’s consider as an example what will happen with different projector screen gains for say a given 1000 ANSI-Lumens projector and a 100" diagonal screen size.
Projector Screen Gain 1 1.5 2Image Luminance in foot-Lamberts 30 45 60
It is clear that our 1000 ANSI-Lumens projector would produce a too bright an image when the latter is viewed in a darkened room, even when using a standard matte white projector screen with unity gain. Similarly, use of this projector in conjunction with a projector screen surface having a gain of 2 may result in a too bright an image even when viewing takes place under normal ambient light conditions.

A Revolution in Home Entertainment Systems - Touchscreens & Media Servers

A Revolution in Home Entertainment Systems - Touchscreens & Media Servers By Steve Faber

Home entertainment systems have come a long way since you ooh’ ed and ahh’ed because your neighbor had a few pairs of speakers that actually fit flush into his walls. That’s old news now. Even homes in comparatively modest new developments are being outfitted with a full complement of audio, network, TV and telephone wiring. In many developments the builder offers a standard wiring package and various upgrades for additional wiring, speakers, wiring enclosures and even full control systems.

Systems have evolved to include sleek, wall-mounted touch screens that allow simple access to your music and other house functions such as security, lighting, HVAC, and motorized window treatments. A talented programmer can make these systems function with true “one touch” simplicity. It’s almost as if they’re reading your mind.

The touch screen’s advantage is that it can change the control interface to only show what you need at any one time. This affords tremendous flexibility while retaining the simplicity people desire. The touch screen interface is extremely powerful when combined with another technology that has come into prominence recently; the hard disc based media server. Your CDs are downloaded, or ripped, onto a hard drive. This combination allows your entire music catalog to be displayed on the touch screen for easy searching. You can typically search by artist, song title, genre, or album. Once the desired selection is located, you just touch it on the screen and it begins to play.

These hard drive servers use computer hard drives and modern compression techniques to store phenomenal amounts of music in a simple audio component less than half the size of a 200 disc CD changer. They function just like a typical CD player, not your computer, so they are reliable and easy to use.

Media servers have exploded in popularity recently because of the enormous popularity of compressed music formats such as MP3 and the fantastic array of functionality a disc based system allows. For those who have, or do, own CD mega changers, a hard drive music server will be like a breath of fresh air.

Access to any song is typically less than a second away. Contrast that to selecting disc 94 in your 300-disc CD changer when you are playing disc 201. With a multi-room audio system, you may be on the other side of your house trying to do this with a keypad or remote control. The wait for your changer to return the disc it was playing then trundle the carousel around to your desired disc can seem like an eternity.

Another advantage is easy cataloging. Most hard drive systems will recognize any CD you insert for ripping and if they don’t, they are connected to the internet for access to a giant database. This they access automatically to gather artist, album and track information. Gone are the days of using a keyboard or remote to tediously enter the information about your CDs into a CD changer. You can also stop worrying about which slot your discs are in. “Let’s see, was Led Zeppelin IV in slot 90 or 190?” Using a hard drive server frees up your CDs for use elsewhere such as your car, boat or vacation home.

In addition, since your CDs are not locked up in a changer, your collection is able to be enjoyed by many members of the family at once. With a changer, if someone is listening to it, all of the discs inside it are basically off limits. With a changer, not only are your CDs free for use in other locations but many hard drive servers provide multiple audio outputs.

Multiple outputs enable you to listen to different discs in different areas of the house if your system is so configured. For example, one person could be listening to Korn in the rec room while Bach’s Requiem is being played in the kitchen and Dire Straights in the bedroom. With a conventional CD changer, this is impossible.

You can also buy and store music from many online music services and store those on your hard drive server. Hard drive servers offer advantages over music files stored on a computer as well. Because they function like a traditional audio component, they are easier to use for many people. It is also easier to integrate them with touch screen based home control systems. This will begin to change as the popularity of multimedia PCs such as those running Microsoft XP Media Center Edition 2005 increases.

These units are many steps closer to delivering the long promised “convergence” between consumer electronics and computers. Multimedia PCs, also known as HTPCs [Home Theater PC] function as DVD players, personal video recorders (similar to a TiVO), and hard drive media storage.

They allow storage of digital photos for easy display on your TV or monitor. HTPCs can, of course, browse the net on your TV via your broadband connection. As hard drive storage becomes more economical and compression techniques become better, the storage of HD movies and HDTV programming will become commonplace.

Soon these types of servers and interfaces will become the norm rather than the exception. You'll think nothing of the amazing array of features offered and the ability to easily access your media collection throughout your home. Once a rarity, media servers, in one form or another, will be found in almost every home.

Flat Panel Displays - Beyond Plasma

Flat Panel Displays - Beyond Plasma By Steve Faber
The term set-top box will become something of a misnomer in the near future, as most displays will become too thin to allow a box to placed on top of them. As the price of plasma & LCD displays has plummeted and their image quality has improved, they are popping up in homes everywhere.

Although they are the darlings of the media and the generic for flat panel display in the minds of many, plasmas are about to be in a serious fight with other technologies for the flat panel crown.
LCD displays, seen on the desktop for years as computer monitors, and commonplace in smaller flat panel TVs, are finally increasing in size to the point they are becoming a rival to plasmas in the 42" – 50” size range. Picture quality is similar to plasmas; however LCDs are immune to the burn-in that can affect plasma displays. This burn-in occurs when plasma units are used to display static images such as video game screens and stock or sports tickers.

Plasmas generally have an edge in the ability to produce deeper blacks and more saturated colors than LCDs. Plasmas are also better at producing full motion video than LCDs because of the response time of the LCD panels, although this difference is disappearing.

LCD TVs are a bit more expensive than plasmas at 42" and larger sizes, but they should last a while longer. Plasma displays should last 20,000 – 25,000 hours and LCDs should give 30,000+ hours of useful life. However, the latest generation of plasma displays from NEC is claimed to have a 60,000 hour life. If that is an industry trend, the traditional lifespan advantage held by LCDs may soon disappear.

Currently Sony has a 42", NEC a 40", Sharp a 45", and Samsung a 40" LCD TV or display. Samsung also has the big one, a 46" that started shipping in early September of 2004. The Samsung 46" was the first consumer LCD video display to have a 1080 line native resolution. This allows it to display 1080p native when that format arrives for HDTV.

Other technologies are on the horizon as well. One that has shown great promise is OLED, for Organic Light Emitting Diode. Developed by Kodak and Pioneer, this technology has been used for a few years in car stereo and cell phone displays. It's just about ready for prime time. Philips has shown a 13" unit, Samsung a 17", and Seiko-Epson has shown a 40" prototype.

OLED’s advantages are many. It actually emits it’s own light, so it requires no backlight and has better contrast than a traditional LCD. OLED displays have a wide viewing angle like a plasma display. Power usage is very low, less than 1/2 that of a traditional LCD display. At around 2mm deep, OLEDs are much thinner than either a plasma or LCD.

They have a refresh rate about 1,000 times faster than a traditional LCD, so they will be far superior for video applications. They have fewer parts than LCD or plasma and can be manufactured using a novel ink jet printing process. This promises to keep prices low as the technology is implemented. It is expected to see sub 20" displays in stores by 2006 with larger units following one to two years later.

Other promising display technologies on the horizon include SED (Surface-conduction Electron-emitter Display) and carbon Nanotube. SED was developed by Canon, who began research into the technology in 1986. SED is basically the same principle as CRT, however there are important differences. The most important from a consumer standpoint is thickness. An SED display is only an inch or two thick, depending upon screen size.

The basic construction is two glass plates separated by a vacuum. One of the plates is coated with phosphors the other is mounted with electron emitters. Electrons are ejected when a voltage of about 16 to 18 V is applied to the emitters. These electrons are then accelerated by a higher voltage into a beam similar to that in a CRT display.

The visual advantages of SEDs are as for CRT displays, great color, deep black levels and quick motion response. These advantages, combined with the slim form factor, low cost and small power requirement should make for a real winner.

A unit shown by Toshiba at a Japanese trade show in April of 2005 even had it’s contrast ratio up to an incredible 100,000 to 1 by significantly reducing black luminance. Even if the specs were a bit inflated this would still amount to a fantastic contrast ratio, on the order of 5 times that of a traditional CRT. Toshiba has indicated they will move to this technology for all displays over 40” by 2006.

One fly in the SED ointment however. On April 21st, 2005 US firm Nano-Proprietary has filed a suit against Canon in the U.S. District Court of the Western District of Texas, alleging that the surface (SED) televisions that Canon plans to release violates a licensing agreement signed 5 years ago between the Japanese giant and Nano-Proprietary.

The pace of change in the home theater and entertainment display market has just kept accelerating. There are some promising technologies around the corner that will allow, as usual, higher performance, lower cost and more compact form factors. As prices for advanced technologies plunge and technology improves, it will make it even easier for the average person to have a fantastic media system almost anywhere in their home.

EDTV: What You Should Know Before You Make That Purchase

EDTV: What You Should Know Before You Make That PurchaseBy Simon Canfield.

Enhanced Definition Television – also known as EDTV – is one of the many modern viewing technologies of our time. Often confused with HDTV capability, this is actually a compromise between standard TV and HDTV. In fact, the visual benefits are at least twice that of standard television, since EDTV technology offers a minimum resolution of 480p when used on a monitor. As a result, you’ll find that this type of system is more expensive than standard television, yet cheaper than HDTV technology.

While there’s been a hew and a cry to purchase the more expensive – and higher quality – HDTV, there are actually some advantages to the “second best” EDTV version. First, there can be as much as a $1200 price difference between the two, and – in some scenarios – the viewing quality of EDTV is superior to that of its pricier counterpart. For instance, there’s only a 10% difference in quality when you’re viewing two plasma TVs that have been produced by the same manufacturer, but the EDTV soars above HDTV when the incoming picture has a lower resolution than the monitor’s regular resolution. This is because EDTV technology allows it to align better with the incoming signal.

If you have an extensive DVD collection, or simply prefer watching movies via DVD, then the EDTV will offer a better video experience. Why? Simply because the DVD, which offers a 480p picture matches perfectly with that of EDTV –which is also 480p. That, in addition to the fact that most content isn’t high definition, but happens to have a pixel count that matches beautifully with the “lower quality” EDTV system, makes this a better buy. Higher contrast ratios are also better in the EDTV arena, which makes the viewing of darker scenes more superior. In fact,even high definition quality transmissions only suffer a 10% difference in quality between EDTV and HDTV – yet, the price of the former is significantly less.

It’s a given that if you purchase a set that’s of lower quality, then even EDTV resolution will suffer. If you’re going to invest in a system that offers higher technology, then you should also be prepared to make the same decision when it comes to investing in the set which will receive the images. So, models that come from Sony, Pioneer or Panasonic will tend to offer a better video experience thanthat which comes from an inferior manufacturer.

The bottom line is that – dollar for dollar – buying an EDTV system is a smarter decision than purchasing the HDTV.When comparing price, difference in viewing quality and the ratio of programs that are actually offered to the general public in a high definition format, the EDTV wins, hands down. So, before you go out and spend about $1200 more than you need to, consider investing your hard-earned money into the EDTV technology. You’ll rarely notice the difference – until you check your bank book, that is; then the difference will become obvious. After all, there’s always the possibility that the chasm between the two systems may increase in the future, but think of all of themoney that you can save, in the meantime.

LCD vs. DLP TVs

LCD vs. DLP TVs By Bradley James
Two new technologies in the world of TV, DLP and LCD, are now in a tight competition. Not long ago, everyone was talking about Plasma and LCD - which one would win? It became clear to most that Plasma, with its short lifespan of just 3-4 years, was simply not the best choice. In fact, the LCD screen has several benefits over plasma. For instance, LCD screens run much cooler than the average plasma TV, and thus require less power to operate. Plasma TVs run so hot, in fact, that they require a fan to cool them down – which can be noisy. In addition, plasma screens have a tendency to degrade over time, slowly becoming dimmer. LCD screens, on the other hand, run relatively cool, and do not degrade over time. Some Plasma owners, who have used their TVs for a few years now, have already witnessed the dimming of their screens. Also, LCD screens tend to have overall better picture quality, and are typically 10 to 15 percent lighter than plasma.

Now the choice is mainly between LCD and DLP - two distinct technologies that offer slight differences in display, price, and performance. If you are looking to buy a new flatscreen TV this year, you are probably wondering which one is right for you.
What are DLP, LCD TV Screens?

DLP stands for Digital Light Processing, while LCD stands for Liquid Crystal Display. DLP technology, developed by Texas Instruments, uses a DMD, or Digital Micromirror Device, contructed of 1.3 million microscopic mirrors. Each of these mirrors is essentially a single pixel. When a digital signal enters the DLP system, each mirror is either activated or not, resulting in tapestry of mirrors tilting either towards the DLP light source or away. This process produces different levels of light and dark reflected by each individual mirror. The colors are produced when the DLP light sources run through a red, green, and blue color filter on a moving wheel. Depending on the lightness/ darkness of each mirror, the colors come in an enormous amount of shades, producing vivid color images.

LCD screens are made of several polarized glass panels, between which are liquid crystal molecules. An electric current is run through the crystal molecules, changing their position in respect to the glass. As light passes through the molecules, these changes in angle result in different lightness/ darkness patterns that produce images on the screen. There are usually three polarized glass panels, one with red pixels, blue, and green. This system also produced very accurate, vivid images, but angle is important. You may notice that the best colors in an LCD display are seen straight-on.

Is DLP, LCD TV Screens better than the other?
Simply put, that is a difficult question to answer. Unlike Plasma TV screens DLP and LCD last much are longer, and are considered to both have superior image quality. LCD screens tend to have slightly better contrast, with a larger range of black and white color shades. DLP, however, still has faster refresh rates than LCD (although LCD has been vastly improved in this area over the last two years). This can have implications if you are really into high-action motion (sports, action movies), because movement may seem a little blurred with LCD at times. Also, you'll want to remember that in order for you to get the best color out of your LCD, you have to sit right in front of it. LCD TVs also have a slightly shorter lifespan than DLPs, with only 45,000 to 60,000 hours compared to 75,000 hours or more. As far as price goes, LCD and DLP are still more expensive than Plasma, but like all things in time, their price has been coming down. And right now, DLP is slightly more expensive than LCD, but not by much. DLP, in our eyes, is the best investment, at least for the next few years.Click here for popular DLP TV units and prices.

HDMI or Component: Which is Best?

HDMI or Component: Which is Best? By Kenny Hemphill
You've just bought a new HDTV, complete with HDMI connector and are delighted that you had the foresight to buy a DVD player with HDMI interface a while ago, even though you couldn't use HDMI at the time.

So you can ignore those component outputs and inputs and plug an HDMI cable between your two favourite bits of home theater kit. After all, HDMI, being all digital, is bound to be better than component, isn't it?

Well, no, actually. Not necessarily. It's true that convering a DVD signal to analog, sending it over component video and then switching it back to digital in the TV will result in a slight degradation of picture quality. And it's true that HDMI removes this issue. However, the degradation in the signal over component is virtually imperceptable and HDMI does introduce a few problems of its own.

Firstly, although DVD players "up-convert" video from 420p resolution to the native resolution of the HDTV (720p or 1080i), the signal still has to be "re-clocked" in the television before it is displayed. Some experts suggest that this re-clocking introduces more artefacts than the process of digital-to-analog-to-digital conversion. And the quality of the processor in the DVD player doing the "up-converting" is important here, if it's not up to scratch that could have a negative impact on picture quality.

Secondly, any equipment with HDMI (or DVI for that matter) connectors must support an anti-piracy measure known as HDCP (High Bandwidth Digital Content Protection). This takes the form of a code which is embedded into the digital video signal when its sent from a content player, such as a DVD player, and must be de-coded by the HDTV or HD projector. This puts additional pressure on the TV's video processor with no benefit to picture quality and so could, potentially, result in a slight loss in picture quality.

Using component video connections means that no anti-piracy protection is necessary.
None of this means that you should avoid HDMI. However, it does mean that you shouldn't take it for granted that HDMI will always be better than component. The only way to find out which is best for your equipment is to try both and see which one you prefer.

HDTV and the iPod Photo: A Perfect Marriage?

HDTV and the iPod Photo: A Perfect Marriage? By Robert Armstrong
They may seem like an odd combination, but the iPod photo could be the perfect choice for anyone who wants to view photo slideshows on an HDTV. The iPod photo can store thousands of digital photos, and syncs with a Mac or PC via iTunes. It will read any slideshows you’ve created in iPhoto on a Mac or Photoshop Album on a PC and copy them to the iPod. Alternatively you can tell it to copy a folder full of images from your hard drive as a slideshow.

Also, with the addition of an optional camera connector($29), you can copy photos directly from a digital camera and automatically create a slideshow from them on the iPod photo. All slideshows can be set to music.

To connect the iPod photo to an HDTV you’ll need to first make sure that your HDTV has composite video and audio inputs and then purchase the iPod photo AV cable ($19) from Apple. Connect the iPod to your TV, select the appropriate input and hey presto, your slideshow can be seen in beautiful, bright widescreen glory on your HDTV.

It’s worth bearing a few things in mind when creating slideshows for HDTV. First of all, the screen of an HDTV set has an aspect ratio of 16:9 (length: height) so if you size your photos with this aspect ratio you’ll be able to fill the screen without cropping the photo or seeing ugly black space around it. Secondly, the resolution required for optimal viewing on HDTV at full screen is less than that needed for printing even an A4 image. So if you only intend viewing your photos on-screen, whether on your computer or HDTV, you can save space on your iPod photo by reducing the capture resolution on your digital camera. If you set it at three mega-pixels, that will be enough to allow you to crop photos to the correct aspect ratio and still view them at the highest possible quality on an HDTV.

Of course, the iPod photo can store more than just photographs. Anything that can be saved as an image file, such as JPEG, can be included in a slideshow, so you could even use it to carry around business presentations which can be viewed by anyone with access to a TV or projector.

How Many Songs Are In Your Pocket?

How Many Songs Are In Your Pocket? By Rick David
The portable MP3 player continues to be the hot item for those who want music on the go. I was talking to a teen the other day wearing a wristwatch MP3 player she takes on her walks. She showed me how it stores & plays about 60 songs and does everything but tell time. “Cool”, I said, “That’s a lot of music.” “Yeah, it’s not an iPod, but good enough for me now.” She explained apologetically. Why was the 60 song capacity such a disappointment? I can’t even name 60 songs.

Well, the iPod is the undisputed king of all MP3 players and it holds a lot of music. I got my first real demo from my 16 year old niece last Christmas. Her cute and wanting little sister threatened to enter the work force early to obtain her own. Every kid wants one bad, but read on, these gizmos aren’t cheap!

The iPod has caused the rebirth of Apple Computer, Inc., which has sold over 10 million units as of Q1 2005, with annual sales growing at a respectable 525 percent! I haven't seen that kind of growth since the invention of toilet paper. Apple has also become an industry-leading innovator in selling music online from their iTunes website.

Take an iPod Tour
The iPod Shuffle is the baby of the family, offering 512MB of space, which can hold about 120 songs and set you back $99.00. But everyone must ask themselves in the mirror, "Can you show your face at a party packing only 99 songs?" If you’re not sure, better buy a little insurance in the form of the 1-gigabyte Shuffle, which can hold 240 songs. ($149.00) Your peers will recognize that you’re in the iPod game, albeit entry level.

For some, 240 songs barely scrapes the surface dust of their collection, coercing them to consider the iPod Mini which can hold 1,000 songs ($199) or the 6GB Mini, which holds 1500 songs. ($249) I noticed that Apple is still using diminutive adjectives for this product level, and I guess the message is that the "Mini" is for a puny music collection that is tiny and rather small-ish. So be careful when giving this one as a gift. "Here son, I got you an "iPod Mini" for your birthday!" "Thanks Dad, but what do I look like, a baby? It only holds 1500 songs! They'll laugh at me! " "But son, my generation needed a moving crane and a 3 man crew to bring in a machine that could play that much music." "I thought you loved me..."

If your unsure of the size of your child's music library, the "regular" iPod is the way to go. ($299) Everyone on this level is "normal" and "common" and no one can be singled out for ridicule. Perfect for a young teen! And 20GB of space gives you that benchmark 5,000 songs, which is probably considered usual and customary in a world economy that had a ten-year run at emptying the product off the digital shelves of the record industry for free.

Granted, there are many who would beg for death rather than leave the house with so many songs left behind on their ‘big’ computers. The 60GB iPod Photo ($449.00) would be the choice for them. It can hold 15,000 of your favorite songs, or 25,000 of only your best looking photos. I keep my 25,000 photos in bins out in the garage. (Admittedly, they're a little bulky to carry around, and I have difficulty with retrieval when I desire to look up a particular birthday or holiday memory.)

But if you’re buying any of these for your kids birthday, better up their allowance, or put them to work down at the mill because these iPods are specifically designed to download from the iTunes website for 99 cents a track.

Napster
Napster began hollering “Do the Math!” from the sidelines with a spot during the Superbowl. They spent $2.2 million to ask the question, “How much does it cost to fill up your player?” The spot is no longer on the company website, but it showed a guy in the Superbowl stands holding a sign that read, "Do The Math"

iTunes + 10,000 songs = $10,000.00

Napster + MP3 player = $15.00 per month

It appears like Napster wins the championship of MP3 players hands down! Napster has a million songs that you can download day and night for only $15.00! (I wonder if they paid for all those.) But there was a sentence printed in the ad, that was so small I didn’t catch it on my father-in-law’s big screen which takes two houses to contain. They only flashed it for a moment so it must not have been important. I looked it up later: “Subscription must be maintained to continue to access songs downloaded from service.” Turns out, with Napster’s service, you’re not buying, but rather, you're renting the music. You can't burn them onto a CD and you can only use them on certain MP3 players. When you quit paying the $15.00 per month, the music disappears...no matter how long it took you to download it all. If you want to buy a song from Napster, it will cost you... drum roll please... 99 cents! So is the real math?

iPod = Napster?
So my music loving friends, here is how I add up the numbers:
For $9900 you can download 10,000 songs from either Napster or iTunes and own them. Or for the same price you can download an unlimited amount of songs from Napster for 55 years, but you can't leave them to your children.

Buying the Best Digital Camera for Your Needs!

Buying the Best Digital Camera for Your Needs By Kevin Rockwell
Choosing a digital camera can be a daunting task with the wide number of choices available in today’s market place. There are lots and lots of things that you need to keep in mind while going to choose a camera for yourself. The best digital camera for your friend might not be the best option for you.

So, the first question that you need to answer is that for what purpose you are planning to buy a digital camera. Is it to take photos of your family while on vacation or are you planning to become a photographer? This will help you to narrow down your choices to a limited few. So lets take a look at the options that we have : A camera for emailing photos, taking family photos etc. : Most people use a digital camera for taking personal photos and then emailing them to family and friends. For this purpose, a simple and relatively cheap camera costing $100 to $200 and having a 2 mega pixel range is sufficient.

A camera for photographing images for online auctions : With more and more business taking place through the Internet, you might also need a camera to take photos of your antique furniture which you would like to sell. So, you need a camera which can take pictures at an extremely close range, say within 12 inches of the object. Thus, a camera consisting of 3-4 mega pixel is suitable for such purposes. The prices of these cameras are falling nowadays since they fall into mid-segment, i.e. they are neither hi-fi nor low end. So if you go and do a little bit of research, it is most likely that you will hit a good bargain.

A camera for images of top quality for web pages, desktop publishing etc : Now, if you need a camera for taking pictures for desktop publishing or web site development, then you need one with a 4-5 mega pixel range. These cameras normally have lots of additional features which you can use to enhance your images. Even though they are quite costly, they provide the best options with respect to resolution, features, and creativity. They also allow you create prints up to 8x10 inches in size with very good quality. Besides the above points, you also need to consider other issues such as the ergonomics of the camera. How does it feel when you hold it in your hand ? Are you comfortable with its size and weight ? Is it practical to carry it throughout the day ? Is its shape user friendly or does it look like a gizmo out of Star Wars ?

If you emphasize on a light-weight and small camera, then you must also keep in mind the fact that you will compromising on the battery life. Most small cameras do not have powerful batteries since larger the battery, more the power. Also, small cameras have very small flash lights – so the amount of flash generated by these pea-sized flashes will be considerably less than a bigger camera. Hence, it is very important that you know exactly what you need your camera for in order to ensure that you are truly buying the best digital camera for yourself. Find the best comprimis between form and function that fits the bill in your digital camera lifestyle.

Don't forget to take lots of pictures when you do get into digital. That is one of the great things about these cameras. No penalty for bad photos. Hit the erase button and move on to new images, that is my motto.

Getting the Most From Your Digital Camera Memory Card.

Getting the Most From Your Digital Camera Memory Card By Kevin Rockwell
Imagine taking your new digital camera on a vacation and then realizing that you can barely click 20-30 images at a go. So, what do you do to avoid such a situation? The answer to this question lies in the purchase of an extra memory card or two.

One of the important components of a digital camera is the memory card. Most digital cameras come with quite a low amount of memory and it is always better to include the cost of a memory card while purchasing a camera. There are several types of memory cards so you must check out the memory options available in the camera that you are planning to buy.

Also, remember that if the resolution of your camera is high, then you will also need a high capacity memory card. There is no predetermined number of images that you can store on a particular memory card. It depends on the kind of images, the file type of the images and the compression rate per photograph. Normally, a 128 or 256 megabyte card is adequate for the average photographer using a 3-5 mega pixel camera.

There are several types of memory cards available. Here is a list of the kinds of memory cards available in the market today:

· Compact Flash Memory Card: Compact Flash is a relatively cheap memory card. It is available in most shops and is compatible with a large number of digital cameras. It is very popular and is commonly used by camera lovers. These cards come with an in-built controller which results in high transfer speeds. However, in order to use this facility, you normally need to be using a digital SLR.
· Secure Digital & Multimedia Cards: Commonly known as the SD card, these cards are one of the smallest memory cards which are available today. These cards can be used in different types of equipment, i.e. digital cameras, phones, MP3 players and video cameras as well. However, the maximum memory capacity is only 512 MB. The difference between the SD card and the multimedia card is that, as the name suggests, the SD card comes with an additional write-protect switch for data security.

· Memory Stick: The memory stick is an invention by Sony. As a result, these cards can mostly be used only on Sony devices. Hence, if you have a Sony digital camera, a Toshiba laptop; then it is most likely that you will not be able to use your memory stick on both equipments. It is a very durable and rugged memory option. So, unless and until you are a Sony fan, the memory stick has limited use for you.

· Card Reader: Once you have purchased a memory card for yourself, you will also need a card reader in order to transfer your pictures onto your laptop or PC. The advantage of a card reader is that it can be directly attached to your computer through the USB port. Then you simply need to slot in the memory card into the reader, and you can transfer files easily. The card reader does not require any additional cables and neither does it use up the battery of your digital camera.

The bottom line with digital camera memory cards is that you need to always have more on hand than you need, prices are often very affordable, and you should choose your camera based on the version of memory card that it takes. Don’t buy into a camera system if you feel the memory card will not accommodate your photo taking needs.

Expert Guide to DVD Camcorders

Expert Guide to DVD Camcorders By Kenny Hemphill
Thinking about a mini DVD camcorder? You're not alone, it's a rapidly growing sector of the camcorder market, with Hitachi, Sony and Panasonic all making more than one mini dvd camcorder.

These camcorders differ from regular digital video cameras in one important way - they record video onto mini DVD discs, rather than DV tape. This has a number of advantages. DVD discs are more robust than tape and won't get chewed up in the camera. Although this is thankfully a rare occurance, it scares me every time I here a strange noise coming from my camcorder, so it's with bearing in mind. The second advantage is that DVD discs are random access, compared to tape on which everything is recorded sequentially. This means that there's no need to rewind and fast forward to find the clip you're after, just select it from the menu. Some cameras even allow you to perform basic editing functions on-camera. An additional side-benefit is that a mini DVD camcorder doesn't have tape heads to get worn or dirty as happens in regular mini DVD cameras. And thirdly, you can easily watch your home movies by removing the DVD from the camera and playing it in practically any DVD player.

However, there are negative factors to. The most siginificant one is that video is encoded as MPEG-2 on a mini DVD camcorder, as opposed to DV format. This means that it needs specialist software to edit - you can't just use your regular video editing program (unless it specifically supports MPEG-2). And if a Mac user you're out of luck, as there are no MPEG-2 editing applications for the Mac.

Also, mini DVD camcorders tend to cost more than similarly specified mini DV cameras. And the media is also more expensive. However, if you don't intend editing your movies and don't mind the extra cost, a mini dvd camcorder does offer extraordinary convenience.

The Future Arrives As Ultra-Wideband (UWB) Becomes Reality.

The Future Arrives As Ultra-Wideband (UWB) Becomes Reality By Stan Allen
As the Consumer Electronics Show is kicking off 2005 in Las Vegas, one of the stars promises to be the emerging technology of Ultra-Wideband (UWB). UWB is wireless networking that is used for a multitude of electronic components and devices ranging from high definition TV, portable digital devices, to your traditional computer. UWB promises to blow away the current home wireless connections we are used to.
How will we use UWB? UWB could replace all of the wires and cables used in a home entertainment system. Your portable MP3 player could stream the audio to high-quality speakers placed anywhere in the room. A digital camcorder or still camera can play back the pictures on your TV without a wire connection. Your large LCD or plasma TV screen can be hung on any wall with no wires to attach. The wired USB connected peripherals could become obsolete as wireless UWB effectively makes the connections. That means you could set your mobile computer on a desk and be instantly connected to your printer, scanner and VoIP headset. In a word, wires may become a thing of the past.

UWB is seeking to make the "unwired" home a reality. To make this possible, UWB provides the vehicle to connect television programs, movies, games, output from hand-held devices, etc. without interference from other wireless transmissions. Current technologies have not been fast enough to route high bandwidth applications around the home without the use of wires or cables. Now the means exist with low cost, low power, high speed UWB.

The effective operating range for UWB is approximately ten meters or thirty feet. In this range, ultra-wideband operates across a wide range of frequency spectrum through the transmission of a series of very narrow and low power pulses. This provides much less interference than the narrowband radio designs. By incorporating UWB with the 802.15.3 PAN standard, it will provide a home wireless multimedia network that supports multiple devices without interference with other UWB networks of the neighbors.

There are other apparent advantages to the UWB technology. Since the UWB transceivers operate with low power, short burst radio waves, they are very easy and cheap to build compared to the traditional transceivers. The UWB systems consume around 1/10,000th of the power that a cell phone consumes. This makes UWB easily usable in small devices like cell phones and PDAs where small power consumption is a big advantage. Because of this low power operation, there will be little interference with other systems. In a recent test, an ultra-wideband transceiver yielded fantastic performance while operating in close proximity to an 802.11b network, a cordless phone, a microwave oven and a cellular/PCS phone.

The Federal Trade Commission (FCC) recently granted certification to Freescale Semiconductor, Inc. for commercial use of the UWB technology. Freescale Semiconductor, Inc. and Universal Scientific Industrial Co., Ltd. Are collaborating on a UWB-enabled 1394 module and are the first to harness the benefits of ultra-wideband and the 1394 standard. They expect to sell the module to leading consumer electronic manufacturers for use in wireless LCD televisions and a variety of home media devices. Other companies, such as Intel, are working on different versions of the ultra-wideband module.

What had been speculation is now moving into the production stage in 2005. The way we use wireless will be rapidly changing when the standardization for ultra-wideband technology becomes set and all the devices are able to take advantage of a universal playing field. The winner will be the consumer as an exciting new world opens up for UWB wireless applications.

EDTV vs HDTV

EDTV vs HDTV By Kenny Hemphill
Confused by EDTV vs HDTV? We don't blame you. The number of acronyms floating about with regard to digital TV is frightening. What's even more worrying is that very often they are used by people who have little or no knowledge about what they mean. If the person selling you doesn't know the difference between EDTV vs HDTV, how are customers supposed to decide which TV or projector to go for?
In our guide below, we've tried to distill the technical info into as few words as possible and make it as straightforward to understand as we can.

To properly explain EDTV vs HDTV, we need to step back a bit. Traditional TV has 525 lines of video which are interlaced. Interlacing just means that every frame of video is split into two fields and each field is shown alternately. Although there are 525 lines in the signal, only 480 lines contain video, so it is sometimes referred to as 480i (480 lines interlaced). This is known as Standard Definition TV, or SDTV. While this has worked well enough for fifty years, as TV sets have got bigger and projectors more popular, the quality deficiencies have become increasingly apparent.

The ultimate answer to improving the quality of the image displayed on your TV is HDTV, however, as a step on the road to HDTV, the industry came up with Enhanced Definition TV, or EDTV. This system contains the same 480 lines as SDTV, but they are progressive scan. Hence EDTV is also known as 480p. Progressive scanning just means that instead of splitting the signal into two fields and showing half the lines at a time, all 480 lines of video are shown at once. This results in a noticeable improvement in the quality of video.
The bad news in relation to EDTV vs HDTV is that you need a completely new TV or projector to display both EDTV and HDTV. Most DVD players on the market today are progressive scan, meaning they output EDTV signals, however, in order to view the progressive scan picture in all its glory, you need a TV or projector capable of displaying it and that, unfortunately, means getting a new TV.

In terms of content, there is very limited TV content available in HDTV format, and there is still wrangling about the standard for HD DVDs. However, every DVD disc on the market can be displayed in EDTV right now. Bottom line? Pretty much every HDTV projector or TV on the market today will display EDTV as well. So even if you live in a country or area where HDTV content is limited or non-existent, it is worth it to watch your DVD collection in EDTV, the difference between SDTV and EDTV really is that big.

Converting Formats Should Be Legal

Converting Formats Should Be Legal By Tim Smith
This is the official stance of K.A.P.A. (Karaoke Anti-Piracy Agency...essentially the RIAA of the karaoke world) taken directly from their website:

Q. If I own my own discs, can I load them onto a hard drive to play them in a show, etc.?
A. No, you MAY NOT load songs from other manufacturers on your hard drive. The licensing rights for music on a hard drive machine exist only between the machine manufacturer and the music provider. These rights do not extend to the owner of the machine, to load songs from other manufacturers on the hard drive player. Copying the discs on to a hard drive is still copying the discs. Legally, it is absolutely no different than burning a copy of the discs. In order to copy your discs on to your hard drive, you have to have the written permission of the company that produced the discs and owns the copyrights.

On this page I will attempt to convince you that format conversion should not be a crime and that businesses should be allowed to convert a phonorecord (That's the legal definition for a song) from one format to another. I am not making a case for piracy, the legitimacy of Peer to Peer networks, nor serial copying, but rather the simple process of encoding a compact disc to a compressed digital audio format like MP3. With piracy and serial copying, the artist is not paid for their work. With format conversion, it is assumed the work being converted was legally purchased, and thus the artist was paid his share of the royalties.

We'll begin with a little bit of history on the DJ industry. When the DJ industry first started, vinyl records were the most popular medium for their performances. How ever, these were heavy and easily damaged. Because of their weight and cost, many DJs only brought a few hundred records to a performance and much money was spent replacing records that hard worn out or become scratched. While this was good for the record industry, it was bad for consumers because it increased the costs for the DJ which were then passed on to the consumers. When the cassette tape was introduced, most DJ's began using them instead because they were lighter and more durable. It was impractical to copy records on to cassette tape because the noise of the record (especially if it was worn) combined with the tape noise made for a poor quality recording. While tapes were more durable than records, they too wore out. Again, this was good for the recording industry because it meant that DJs would have to purchase the same record they already owned in the cassette format. Of course, this cost was passed onto the consumers through higher prices charged by DJs. When the CD came out, DJs switched formats again. They now had a digital medium that wouldn't wear out no matter how many times it was played. It weighed less than a tape, and it offered the ability to find a particular track as quickly as DJs used to be able to with vinyl records. Now instead of bringing a few hundred records, or several hundred cassettes, DJs could bring one or two thousand CDs. This meant DJs had a consistent product and a wider selection of music than a band, so not surprisingly DJs are now the entertainment of choice at weddings and parties.

Now enter compressed digital audio. Most people are familiar with MP3, so I will use that term in place of compressed digital audio, however most DJs use other better compression formats than MP3. With the MP3 format, DJs can store not just one or two thousand CDs worth of music, but hundreds of thousands of CDs. Since MP3's are digital, they never wear out, and because they reside on a computer hard disk, they never get scratched. In 50 years they will sound the same as they do today. They take up less room because they are inside the PC, and not spread out on a 3 foot by 6 foot table. They are lighter because they are not a physical "thing". And since computers are really great at sorting information, requested music can be found instantly by the DJ instead of forcing him to search through thousands of CDs to find that one particular CD that has that one requested song. Compressed audio is a godsend for the DJ because it means he never has to replace a disc/cassette/record, he has less to carry, he can offer the widest selection of music possible, and reduce his cost. This is great for consumers because lower costs mean lower prices.

Some argue that compressed audio does not have the same sound quality as a CD, and I have to agree. However, it takes a very good ear and a good set of speakers to detect a difference between a high quality digital encoding and a CD. In a large hall filled with celebrating people the two are indistinguishable. Further, I would point out that CDs do not sound as good as a high quality analog recording like a vinyl record, but the public still embraced compact discs with open arms. The public seem quite happy with a good recording that is more durable than a great recording that degrades.

Unfortunately, as with every invention that threatens the status quo, it is illegal. Currently disc jockeys who convert a CD to another format (including another CD) are breaking copyright law because such a conversion is not considered "Fair Use". The courts use four factors set forth in section 107 of the Copyright Law to determine if a use is "Fair Use":

1. The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes.

2. The nature of the copyrighted work.

3. The amount and substantiality of the portion used in relation to the copyrighted work as a whole.

4. The effect of the use upon the potential market for or value of the copyrighted work.

In the case of Disk Jockeys, the questions would be answered as such:

1. Commercial use for private performance. It is a private performance because Joe Public can't simply walk into Jane Doe's wedding without an invitation, nor can he attend ACME Corp.'s company Christmas party unless he works there, but because the disc jockey is charging for his service, it is a commercial use.

2. The nature of the copyrighted material is a creative work. Creative works typically afforded a more restrictive definition of Fair Use than informational works like dictionaries and encyclopedias.

3. The entire work is used in the format conversion process. This should be seen as a plus, since the disc jockey is not altering the work in any way. The DJ is faithfully reproducing the entire work as intended by the artist.

4. The effect of this conversion increases the potential market for and the value of the copyrighted work. By allowing disc jockeys to convert formats, they will be able to carry more music to a performance, and potentially bring the artist more fans and ultimately more fame and money.

To add this all up, the fact that it is commercial use of a creative work argues against fair use, but the fact that the entire work is used and its use potentially increases the market for the artist should outweigh the negatives. The fact that it is a private performance is fairly neutral.
Another reason it is illegal is because the CD is not consumed during the process of conversion, so by nature of the process one is left with 2 copies of the recording instead of the one that was purchased. In theory the DJ should pay for that second copy. Unfortunately, no method for paying for this second copy is available, and since many DJs would rather have the music in digital format than CD format you would find them selling the CD after making the conversion which would hurt record sales even more since you would now have a glut of discs flooding an already battered market. This would be legal if the DJ were forced to pay for the copy, as the original CDs carry the Right of First Sale (which means you can sell it at a garage sale, sell it on eBay, or trade it in at a used music store). Having the DJ pay for the created copy would imply its legitimacy as a legal copy in and of itself, and thereby imply the Right of First Sale to it as well.

"What can I do about this?"
If like me you feel that the music industry is trampling your rights, contact your state senators and representatives and let them know that your vote is more important than the money they get from the music industry's special interest groups.

Tim Smith is the owner of By Request DJ & Karaoke Company and has worked towards getting US disc jockeys the right to use compressed digital audio since it became legal in Canada.
