It all began when a 20year old German student, Paul Nikpow, put forward his theory of the rotating disk'. The inventors tried to build a mechanical television system based on either this theory or tried to build an electronic television system by using a cathode ray tube. The invention of the TV didn't happen overnight, it was a result of the contribution of various people spread over a number of years. Below is a history of the development of the Television with reference to the contributors of its development. Paul Nikpow: he was the pioneer in this field and sparked off the development process. He devised the rotating disk' or the Nikpow disk' in 1884; this could transmit pictures over wires.
[...] It had to be made digital in order to fit into the channels while the Japanese version was Analog. The first demonstration of HDTV in the United States took place in 1981 and generated a great deal of interest. The father of the HDTV in USA is said to be Joseph Flaherty. He is now the senior vice president of the CBS. To help consumers deal with the mounting tide of HDTV-related questions, the FCC created a consumer website http://www.dtv.gov in October 2004. [...]
[...] Examples of true HDTV sources are: 1. Off-air ATSC receivers using HDTV 2. Digital cable Set Top Boxes (STB) that offer HDTV service 3. Digital satellite receivers that offer HDTV service (i.e. DirecTV, DISH Network, et al.) 4. Windows Media High Definition Video 5. HD-DVD and Blu-Ray DVD players Examples of EDTV sources are: 1. DVD players featuring DVI / HDMI outputs (with built-in HDTV scalars) 2. Video image processors (scalers) 3. Digital cable Set Top Boxes (STB) that offer EDTV service 4. [...]
[...] One can buy a flat panel HDTV with 1080i resolution All flat panel TVs display videos progressively irrespective of the signal. The best way to review the resolution is to check its total pixel count.( i.e. 1280x768, 1920x1080) HD videos can't be recorded on regular DVDs Blue laser, Blu-ray disks and HD-DVDs have capacities up to 500GB but usual red laser DVDs can record HD too. a 1080p is better than a 720p TV a 1080p TV has a higher resolution but whether you need the extra pixels depends on the size of your TV and the distance between you and it. [...]
[...] The bill also would provide billion to help millions of Americans buy digital-to-analog converter boxes for their older television sets so those consumers will continue to receive a signal once the switch is made permanent. The HDTV: HDTV stands for High Definition Television. The appeal for High definition TVs are two fold, it makes for better viewing and its surround sound adds to the enjoyment. Let's review the first aspect: Some HDTV models offer six times better clarity than a standard TV. [...]
[...] some HDTV broadcasters intentionally distort the aspect ratio of program material for convenience, e.g. when horizontally stretching the 4:3 source used for the standard-definition version of their channel up to 16:9 for the HDTV version of their channel, resulting in an image where objects are too "short and fat". The proper approach (to obtain a true 16:9 version of the source material instead of horizontally-stretching the 4:3 version) is not always used. This aspect-skewing "shortcut to 16:9" has been observed on several so-called major HDTV cable channels. [...]
