The high definition television has made waves in the current market. But there is something that is between HD television viewing and it is ED resolutions aka Enhanced-definition television. It is also known as the ED TV in the United States of America. ED or enhanced definition lies somewhere between the standard definition television and the high definition television. It is superior to the standard television but inferior to HD TV.
An ED resolution television is a device which manages a display of 480 – 576 line signals progressively scanning and not an interlaced scan which is 480i and 576i. Although it is not as powerful as HD TV, different countries have different view points about ED resolutions. In some places, 576p digital TV is recognised as HD TV while 720p is minimum requirement for HD TV. This is because many a times, televisions which are equipped with technology which lies in between HD and Standard definition, are known to be HD ready. These often display 1280 x 800 panels where as a fully equipped HD TV will use 1920 x 1080 resolutions.
The ED TV requires more bandwidth when compared to an SDTV. It requires a composite video more or an S- video mode. It will require higher bandwidth media to comfortably accommodate more data transfer. If one wants to make use of an ED TV to watch a movie DVD or to play a game, they must make sure the game console or the DVD player is connected via a 3RCA cable or a VGA connector.
In comparison to HD TV, ED TV requires much lesser bandwidth. Hence, due to this, television stations can broadcast numerous ED TV stations at once unlike HD TV. The pixels used for broadcasting ED TV are non square which is similar for standard definition. Similar amounts of horizontal pixels are used in the ratio of 4:3 and 16:9. Most ED TVs have a resolution of 852 x 480 which leads to scaling of any sort of display. When one downloads using iTunes or video games, 852 x 480 resolution is used.
In the absence of HD TV earlier, people found the ED TV a good option. A plasma television is the best option to use when one has ED resolution TV as it can display picture without interlacing the signals.
If one is a keen gamer, then games are best played on ED TV. Plus an ED resolution television is regarded as the best invention since the time of colour television. This is because it offers great video viewing experience to the customers. And it is cheaper than the HD TV of course. So if one is happy with the resolution offered with ED TV and does not want to shell out the extra money, ED TV is their best option. It is, however, said that the picture quality of a HD TV is twenty times better than that of an ED resolution TV.
