What are the key features of High Definition Television?
The first noticeable difference between High Definition Television (HDTV) and the current television system is that the picture is much wider. It is nearly twice as wide as it is tall and closely approximates that of cinema. The second key feature is that High Definition has over six times the sharpness and clarity of analog television. KTVN-DT’s HDTV picture contains 1080 vertical picture lines by 1920 horizontal pixels for a total of over 2.0 million pixels. Standard definition pictures contain only 480 vertical lines by 720 pixels for a total of 345,600 pixels. Third, the color resolution of HDTV is also more than twice the current system. KTVN-DT’s High Definition signal also is capable of delivering six channels of CD-quality surround sound (left, right, center, left rear, right rear, and low frequency effects) when the program is available from CBS in 5.1 digital surround sound. Finally, the signal is digitally transmitted, which eliminates all of the imperfections we have lived
