HDTV

Digital audio coding is the process in which audio is stored and recreated through digital means. It may encorporate digital audio compression, modulation methods and sample resolutions and frequencies.

No. An HD DVD will only play on an HD DVD player. This format was released in competition with BluRay. It lost the battle after about one year and was withdrawn from sale. There are few HD DVD players and discs around and none have been made for a number of years.

the demise of the HD DVD video format should not come as a surprise when the two formats are compared and closely examined. First, the quality of both in terms of picture and sound are a huge step up from a regular DVD in resolution. However, when further investigating Blu-Ray, the storage capacity is four times greater than that of High Definition DVD. In my opinion, this is perhaps the largest deal breaker for High Definition DVD.

Unless the disc has some sentimental value, there is probably little point in retaining it.

Any omnidirectional antenna is a good choice. Many people swear by the Diamond brand discone antennas, but many manufacturers make similar, equally good antennas. If you have a little time, you can even make your own omnidirectional antenna out of an SO-239 connector and some wire and solder. Omnidirectional antennas generally have a vertical section and at least four sections pointing down at 45 degrees. Discone antennas are similar, but have a horizontal disc (or array) in addition to or instead of the vertical element. Any antenna will have better reception with more height and a good low-loss coaxial cable.

Yes. DVD players can play music CDs. Blu-Ray players can also play DVDs and music CDs as well

Generally, televisions only have HDMI inputs. If there is an HDMI output, it may be possible to connect it to the input of another television although HDMI outputs from televisions are frequently limited in their functionality. Check the manual of the television for confirmation of the capabilities.

What do you mean by durable? The screens themselves are very delicate and will not react well to bumps or accidental impact from kids, pets, or overly emotional reactions from husbands watching the Sunday ballgame. I recommend wall mounting the unit to avoid the majority of these possibilities plus it looks fantastic and saves room. If you are talking about longevity, most new sets are rated for lamp lifes of 60000 hours. This is equivalent to having the set on for 8 hours a day for approx 20 years. Of course, 20 years is along time for other issues to occur. I have had my Sharp AQUOS for 3 years now and it is the same as the day I bought it.

"HD ready " says that the television can display an image from an HD signal, whether it is a 1080 or 720 line format. However, it makes no claims about the resolution of the screen itself. Some HD ready screens are as low as 480 line which is the number of lines in an NTSC (North American format) standard definition signal. The image quality will therefore be no better than SD even with an HD signal being delivered to it.

"Full HD" is less well defined. It normally means that the display has 1080 lines and it can show a 1080i image at its native resolution. Some people will say that full HD must allow 1080p signals to be shown at the native resolution and frame rate. Full HD can also mean that the screen is a 720 line display, or higher. As 720 line is a recognized HD format, a display that boasts 768 lines can legitimately be called full HD.

The only way to establish the type of display is to check the detailed specification. Ideally, the display will have a native resolution of 1920 x 1080 pixels and will handle 720p, 1080i and 1080p signals. Any other resolution will demand that the incoming image is resized from 1080 to some other format, so losing quality against the incoming 1080 signal.

The final check for a television is a visual one. Disregard all the specifications and watch the television while it shows the program material that you are likely to be watching. If the display looks good, then it's a good television. That's very subjective but the buyer is normally the person who will be watching it.

Either you plugged something into the tv that it did not like or there is a power supply issue. Just contact the usa call center at 18002117262 to get that taken care of quickly!

Gold is used in electronics for connectors. The only gold in a cable will be the thin plating on the connecting pins of the connector itself. It is used because gold does not corrode and therefore does not suffer from poor connections due to oxidization of the connector surface.

The total amount of gold will be measured in milligrams.

An LCD TV is exactly an LCD screen with fluorescent lighting shining through it. Without the light, you could see very little on the screen.

An LED TV is exactly an LCD screen with LEDs behind the LCD screen shining through it. The LED lighting gives more even color and brightness on all pixels, and results in a sharper image with more 'pop'.

No. The aerial (antenna) has nothing to do with the viewing of Blu-Ray disks.

The Blu-Ray player would be connected to the set by an appropriate set of cables depending on your specific HD TV's available connections. Look for HDMI, DVI, or component cable connections on both the player and the TV. Use the appropriate cable and select the correct input on your TV set.

There are several ways to send video over CAT5. The method depends on the type of signal. Composite video signals can use a passive adaptor at each end of the CAT5 cable. The adaptors normally use a small transformer at the transmitter to match the signal to the cable. At the far end, another transformer matches the signal to a standard video co-ax cable ready to feed into a monitor or television. These are simple adaptors and are relatively inexpensive. Signal paths of several hundred feet are quite practical.

VGA signals need a little more processing. As they have three separate video signals and two synchronizing signals, they need to be processed into only four signals (CAT5 cable has 4 signal pairs). Because of the design of CAT5 cable, on a long run, the red, green and blue signals can become delayed by different times. Although the times are minuscule, it is possible to see the timing errors on a screen. Each of the three colors will become shifted horizontally. To correct for this, good VGA - CAT5 converters will compensate for these tiny delays. This makes a VGA -CAT5 system much more expensive than a standard video system.

HDMI over CAT5 is also now available. Similar to the VGA system, HDMI - CAT5 converters are active units and also need signals to travel in both directions. Although expensive units, they do provide a method to extend the maximum transmission distance of HDMI from 60 feet or so more than 100 feet.

LCD is liquid crystal display, used in computer monitors and handheld devices; LED is a light emitting diode, and are used in some TV's and devices. LED's are the small, bright lights, like a camera or phone flashlight.

This is caused by "wasted" power in the electronics of the TV that is not actually performing the functions of being a TV, in other words the fact that the TV is less than perfectly efficient. This is not only true of your TV, it is true of everything: everything is less than perfectly efficient, everything "wastes" some power, everything heats up when used.

Note: even an electric heater "wastes" some power as although its function is to heat up, some of the power it uses comes out as visible light instead (and even a very tiny bit comes out as microwaves) which in not fulfilling the function of being a heater.

you need to make the dish yourself first. i am working on it. i designing one of 120cm. i need to make 6 similar pieces to make the dish. it is about 360.98cm to the outer side. i will tell the deatils later when i am finished with it. you need to make the dish yourself first. i am working on it. i designing one of 120cm. i need to make 6 similar pieces to make the dish. it is about 360.98cm to the outer side. i will tell the deatils later when i am finished with it.

As fas as I know, for LCD, it's 70 inches. For lEd, it's 65 inches. There is such thing as an LED/LCD TV, where I have a question about it. You forgot plasma TVs.

Ghana uses PAL 50Hz television standards while North America uses NTSC 60Hz. Although some US televisions will operate on 50Hz and PAL color systems, by no means all of them will. It will be much safer to buy locally or at least to buy in Europe where PAL 50Hz standards are used.

There are methods to use North American televisions on European signals but they tend to be cumbersome and expensive.

The difference between digital cable TV and regular cable TV is the quality of the video stream that is being presented on the TV screen. A digital cable will provide a better quality picture, usually with a larger framerate and bitrate and as such these will look better on a larger TV.

Tuning for digital transmissions is complicated because the picture comes in perfect, not at all, or perfect with sporadic corruptions, which you don't see right away when tuning. For more about selecting an antenna and tuning it, read on...

After finding the direction and distance of all the transmitting towers for digital television in the area (from the customized map at www.antennaweb.org), the next step would be to choose an antenna, hook it up, and aim it.

The antenna does not have to be "digital ready". Antennas are pretty much the same for analog and digital TV. (However, it is smart to know the characteristics of digital broadcasts in your area because of the difficulty in tuning to them.) You can start with whatever antenna you have, and if it does not work well enough, then research and buy a more appropriate one for your area. If you have no antenna at all, then try sticking the center wire tip of a cable TV cable into a potato or an orange--just to get an idea of the basic reception in your area. It will last a couple weeks until the vegetable dries out.

You need to be particularly choosy about your antenna if you want to receive channels 2-6, and to a lesser extent for channels 7-13. Channels 14-83 are the easiest to receive digitally, and most any antenna may do for those depending upon the distance and direction. If you are not satisfied with your reception on 2-13, but get 14-83 just fine, then you may want to just be patient rather than investing in an antenna: because of the large degree of difficulty with tuning these stations for digital transmissions, most stations are soon moving to the UHF band, channels 14-83. If you cannot wait, then focus on antennas designed specifically for both VHF and UHF (not only UHF in this case). In deciding whether you need a VHF antenna or not, you must realize that the stations have been renumbered and no longer represent the frequencies they broadcast on. For example, Digital channels 2-1, 2-2, 2-3, 2-4, 3-1, 5-1, 8-1, etc., are not necessarily broadcasted on VHF channels 2-8. To find out the broadcasted channels you must refer to a list like the one at www.antennaweb.org. (However, that website seems to only show the analog and dash-1 digital channels, not the dash-2 thru 5 channels, so another source must be sought).

If all the stations that you want are in the same direction from your house (within 20 degrees or so), then you can use a directional antenna and aim it right at the middle of the stations. Outdoor antennas come in 2 basic types, directional and multidirectional. Multidirectional antennas do not have to be aimed. To aim a directional outdoor antenna, follow the directions from the manufacturer. Indoor antennas are another story. They often come with no documentation, either in the box or on the manufacturer's website regarding tuning or aiming. They may only say turn the antenna until you get the best reception. This works fine for analog broadcasts because you can see the difference in quality when you turn the antenna. But digital broadcasts are different because the picture is either perfect or non-existent, or it corrupts at odd times and stops for a while (closed captioning may turn to gibberish, blocks of the picture turn colors or look like lower resolution, the screen freezes, and then a few seconds later it may restart).

To tune an indoor antenna for digital reception the best method may be to try different positions of the rabbit ears, disc, and dial, and write them down methodically, doing a new complete scan for channels each time, and then count and write down how many channels are found each time. This is a better method for digital because the number of channels found is a better indication of signal quality than the visible picture quality. Be sure not to do manual scans because those function only to add new channels not to count the number of channels receivable. This method would work best when all towers are in one direction. If stations are broadcasting from different directions, then you should write down not only how many stations are detected, but which ones. Then your job is to come up with multiple settings combinations that get all the different stations you want at different times. After you have discovered them all, then do manual scans in each setting (if your TV has that function) to add all the stations. Then, keep a note close to your TV about which settings to use when actually watching each station. You may need only 2 settings to cover all your favorite stations (and in most areas only one setting will probably be satisfactory). The real problem with rabbit ear antennas is that they are not very directional, because they pick up all kinds of shadow signals bouncing off trees, mountains, and buildings. So they are not very predictable. Look into a truly directional antenna (indoor or outdoor), or a high-quality omnidirectional antenna (but beware of fake quality--just sticking some discs and dials on a good-looking design does not mean it will receive the stations you want).

Since modern digital TVs have computers, one function really missing from them (exists in some models?) is a function to evaluate the tuning quality. Wouldn't it be great if your TV reported the signal quality it is receiving for each channel? I am not an engineer, but from what I know of the way digital TV works, it seems like such an easy function that I wonder if it is not already built in to TVs, but just not publicized. I am definitely looking for this function to appear soon.

Its an antenna that can operate in vertical as well as horizontal polarization. Dual polarized antennas are often used in 802.11n devices to enable multi-thread communication. This enables the device to transmit data on one polarization and receive data on the other simultaniously. The advantage of this is that multi-thread communication can be achieved with the use of one antenna instead of using two independent (and opposite polarized) antennas for the same result. Obviously all the networking equipment in the wireless network must be multi-thread complaint for this to work.

Digital TV receivers offer high definition broadcasting and a clear combination of audio and video. Digital TV receivers attach directly to your TV with a cable and do not require any additional hardware.

I think the best times to buy a tv would be near end of the year when companies start selling products to make room for newer produtcs, end of year clearence sales, black Friday, around Christmas time, you can maybe find internet coupon or ones in Sunday paper and compare all the stores produts to find cheapest one, then if you went to the stores with the adveritsements and showed them the ad for a store that has the same product for less just maybe say, I'm interested in buying this tv yet if you brought the price to them show them the ad this store I think I'd like to buy it here to support your store yet if you cant come down on the price I might have to go to this store show them ad, they might say ok and agree to it, plus if you bought the item on sale, plus did the ad comparison throw in a senior discount..lol just joking i think.. you might get a real sweet, sweet almond deal...ok good luck to you..
