HDTV

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 In deciding whether you need a VHF antenna or not, you must realize that the stations have been renumbered and no longer represent the frequencies they broadcast on.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..

The HDMI cable would stop transmitting sound once hooked up to a television if the television and laptop require another, separate, cord for the audio than the visual. The user may also need to set the television speakers on default rather than the computer or laptop speakers being set as default.

VGA is the standard analog interface for computer displays. A television monitor that has a VGA input will be able to display a computer image just like a PC screen. VGA can also be used by video equipment so it can be used as a video signal interface for those items of equipment.

Assuming you are talking about new plasma televisions, the answer is yes. There are not nearly as many as before, but companies like Panasonic, Vizio, Samsung, Pioneer, and Sony are all making various plasma models currently.

HDMI cables are used for the best quality viewing in high definition. One can purchase Monster HDMI cables directly from the Monster website and also from other sites including Amazon, Future Shop and Best Buy.

Both screens are good. The glossy worked best for me. Glare was never an issue for. If video is not your primary use of computer, and you are in extreme lighting situations all of the time, then the matte is a good choice.

Vizio VA19L has a digital tuner in it.

Aminimum of $150 Canadian without cart. but in good to excellent condition.Without cart because the only available cartridge is manufactured by Soundsmith.N.O.S. carts will have deteriated significantly and are not a viable option 35 years later.

buy a AV to RF converter connect 1 tv with AV output and other one with RF out put, some STB have RF out put ,check it and enjoy .but u will have to watch the same channel at the other tv also.

You can, but I'd suggest that it's used only for short runs, maybe up to 6 feet, max. The picture quality will probably suffer due to internal signal reflections, causing ghosting of the image or ssome smearing of the video, but it'll work.

A person would have to know the price of every single HDTV to answer this subjective question. What is cheap to someone else might be expensive to you. The price of HDTV sets has dropped the last few years. Some low cost brands (of course this is subjective) are TCL (The Creative Life), Samsung, and Vizio. This depends on the size of the television and other factors such as apps and internet access.

Sorry to say that you will be unable to download Skype on your LG Smart TV or any other device in UAE ( United Arab Emirates). The reason is that Skype is blocked in that area by the ISPs (Internet Service Providers). This has been the case for quite a few years and is still in effect as of May 22, 2014.

Approximately 1.625 Amps per hour if plugged into the wall. Wattage is equal to Volts x Amps. In my case, my 40" Samsung LCD uses 195 watts, and at 12 volts(for a deep cycle battery), that would be using about 16.25 amps per Hour. I was trying to figure out how long an 80 watt solar panel could power my tv. With a fully charged 55 AmpHour battery, it could probably stay on 3 hours. Don't forget though, you don't really want to drain a battery past 50% because going lower decreases the life of the battery. So figure about 1.5 hours for a 195 watt tv at 12 volts on a deep cycle. For outputs from the wall, I think it's 120 volts, so 195 divided by 120 is 1.625 amps per hour. You might think since there are less amps there is less power, but amps isn't power, watts is. Current is measured in amps. Since there is a higher voltage, there needs to be less current. Think of it like a river. When the water gets deep and the river wide, the current flows slowly but there is still the same amount of water passing through. When the river is shallow and fast, there is also the same amount of water passing through even though the current is faster. I know it's kind of confusing because all the components are tied together, but after a while, you will understand it.

Here's a good website...see related links below.

There are some people who do not tolerate 3D imaging techniques. It's worth auditioning several different brands of television to see if there are any that you are able to tolerate. IF you find a model that works for you, then you will know that you are able to invest in a 3D television if you choose to.

1080i is a term related to high-definition televisions. The 'i' in 1080i stands for 'interlaced', meaning the TV draws lines and interlaces them to show the whole picture. The '1080' in 1080i means there are 1080 lines of resolution.

Almost all of them are now flat screens. The only tube based HD televisions were restricted to broadcast use and at $35000 each, studios were very happy to move to lower cost plasma or LCD screens. I believe that these models were never offered for domestic use, nor for industrial presentation use either - hardly surprising at those prices. I believe that HD CRTs are not being made by any major manufacturer now. The quality of a well set up tube based monitor showing high definition was a sight to behold and flat screen technology has a little way to go to catch up with the older CRT screens. No doubt, the new technologies will develop rapidly in the coming years.

HDTV was not an invention as such. The standards for HD television were developed and agreed between various televisions standards committees and television companies around the beginning of the 1990s. With the standards agreed, a number of companies began developing equipment to support the standards. Along the way, there have been many developments of electronic hardware, software and storage techniques that have enable HD to be captured and distributed.

The first HD televisions for domestic use were released in the late 1990s although they had been available within the broadcast sector some time before the domestic models made an appearance.
