Digital Television

That is how it works. It needs it to validate ownership.

As HDTV made its entrance to the market, HDMI was not available. Because of this, there are a handful of HD televisions that have only analog HD inputs or perhaps RGB inputs.
HDMI was introduced by the television industry as a small and convenient connector for video, audio and control lines between a source and display. The interface is fully digital and happens to support an encryption system that prevents the signal being accessed for unauthorized recording and distribution. Unlike all other video interfaces, HDMI connectors are used under a commercial licence that restricts the use of them. One of the effective prohibitions is to use the connector in a device that decodes encrypted material to any un-encrypted signal such as analog HD links.
For the unfortunate few that have HD televisions without HDMI ports, it is unlikely that there will be a method of watching commercial HD content. It is certainly worth contacting the manufacturer to see if they are able to offer upgrades that may solve the problem. OR if the TV has 'component' inputs, use them and the picture will look great, if that doesn't work, use the S-connector. You will still have use audio cables.

This will depend on your area.

In the UK we have a government-sponsored website which gives you clear detail on what equipment you need and how it needs to be installed, depending on your postcode.

Perhaps you have something similar where you are.

Looks like things started around 1960.

Yes.

If his TV is cable ready and your cable company offers basic cable with out a cable box then just use a cable rated splitter and run the cable to his TV without a box he will only get basic and probably advanced basic. You need a cable box or a TV with a built in decoder to get digital signals.

Remove the ribbon cable connector (BR001) from the small signal board. This cable goes to the front key board. Use your remote to control the TV. You will loose the ON - Off light but the TV will come on with the remote (no indicator light). This also cures the volume from going off automatically.

Sky Ireland offers a digital account which gives you a choice with which television you want use to watch their programs. You can also choose from a variety of cable boxes to watch their channels with.

If you are on antenna TV, it's likely because of the digital transition. A lot of areas that were covered under analog signals now no longer are. While you can get some stations, others might not show up at all. This is a common problem that was not foreseen by Congress in the digital switch.

The DTV Green Dish is a new antenna, partnered with a dish and forms a highly directional, high gain system.

It uses the parabolic reflector to focus terrestrial signals in a similar way to satellite dishes. It is claimed to improve reception with distant transmitters and the makers suggest it will be an improvement in all situations with guaranteed reception of all major channels. Buyers should probably have that kind of guarantee in writing before committing to the antenna. After all, it is breathtakingly expensive at $300.

The antenna is limited to receiving only channels that are broadcast on the terrestrial channels. Don't expect it to deliver the premium cable and satellite channels.

So as to pack in more information.

Broadcasters were required to use the same channel space when they went digital as they were originally assigned by the FCC. However, the new digital hidef information, including the surround audio, would have taken up at least six channels worth of space. By compressing the data (removing redundant info), they're now actually able to put more programming into the same amount of space.

For most people, their old antenna will work just fine.

Don't let the people at the electronics store fool you, there is no such thing as an "HD antenna." There is nothing special that needs to be done to an antenna to receive HD signals. In fact, many of the antennas that are being marketed as "HD antennas" are inferior UHF-only antennas that receive a smaller set of signals than your old antenna.

However, some people who were barely receiving an analog signal may need to buy a better antenna. Also, if the location of the digital transmitter has changed or the signal strength of the TV station has changed, you may need to re-aim or replace your old antenna.

Simply plug the old antenna into the converter box and then plug the converter box into your old TV where the antenna used to go and you will be fine.

The converter box will tune in a digital station (some digital stations are HD, some are not) and convert the digital signal into an old-fashioned analog standard definition signal and feed it into your old analog TV.

You will not be able to watch shows in HD on your old analog TV, but you will be able to watch a version of the HD broadcast that has been converted into Standard Definition (SD) for you. You will be able to watch all of the digital stations including the HD ones but you will see them in Standard Definition. Standard Definition is 480i. Digital to Analog converter boxes receive all tv transmissions of 1080P , 1080i , 720P , 480P , 480i and coverts them ALL to 480i to watch on a standard definition NTSC Analog TV.

Yes, but to a very limited extent.

The most common indoor antennas generally may have rabbit ears, discs, and dials. The rabbit ears, contrary to popular belief, get the best directional signal when they are laid flat with both sides sticking straight out, perpindicular on a plane parallel with the earth, and perpindicular to the line from the broadcasting tower.

The length matters, too, but it depends upon which station is being received. You can set the length in the middle, to the stations you like best, or adjust it for optimum reception for each channel.

Loops should be arranged so that the plane that intersects the entire loop is perpindicular to the line from the broadcasting tower. Discs generally are plastic covered loops and should be arranged the same way.

Dials make some adjustment in the electrical properties of the antenna. Try each dial position, do a full channel scan, and mark the positions that pull in maximum channels. Then narrow it down from there by watching the channels for a while.

Now with that said, these rabbit-ear, loop, disc, dial antennas are not particularly directional because they do not make up for shadow signals that bounce off mountains and trees and buildings (whereas truly directional antennas, outdoor antennas and higher quality directional indoor antennas make compensations for these extra signals.). If the reception is still not satisfactory, then look for an antenna that is truly directional, omnidirectional, outdoor, or has a signal boost.

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...

Going by outdoor antennas (which have definite directionality), antennas specifically marketed as directional have a gun shape to them that you just point. Other indoor antennas are specifically marketed as omni- or multi-directional. With these, there is no problem with aiming. Although they may not be the optimal antennas when all stations are in one direction, they are probably just fine (as I believe they are usually of higher quality than the uni-directional ones.) The information below may also be helpful for aiming and fine-tuning indoor antennas for digital TV reception: 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).

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.

1) TV can teach children how to communicate. Hearing children of death parents have learned to speak through television.

2) TV can show and explain something at the same time. For instance, children can see dangerous wild animals and hear expert commentary on what the animals are doing.

3) TV can take children where they couldn't go in real life, and see things they could otherwise only imagine. Beyond just a still picture and story, children can experience what life is like in another era or on another side of the world.

4) TV can show bad examples and teach good values. Slapstick like Laurel and Hardyis a good tool for teaching children not to fight. Other comedy like Mr Bean helps children to laugh at themselves

If you mean 720 to 1080, If the TV is capable of 1080, it's done automatically in the TV set.
