What is High Definition Television (HDTV)? High Definition Television provides the ultimate in picture and sound quality. HDTV is a digital television format, which combines high-resolution video and digital sound to create a movie theatre-quality TV viewing experience. HDTV also requires the purchase of a separate television and receiver.  Notable characteristics of HDTV are:  1.   The Ultimate Picture Quality An HDTV image contains approximately 5 times as much picture information (picture elements or pixels) as displayed on a conventional TV. The net result is an image far superior to those available today.  2.   A wider, movie-theater-like picture. The picture of an HDTV is wider using a 16:9 aspect ratio as opposed to the 4:3 aspect ratio standard we use today. This results in an image similar to that found in a movie theater. 16:9 HDTV Image Shape        4:3 NTSC Image Shape         3.  Better sound quality. The sound format adopted for HDTV is Dolby Digital. CD-quality movie-theater-level Dolby Digital 5.1 sound can be achieved (when present in the soundtrack).  4.   Available today - Bell ExpressVu Model 6000 High Definition Receiver.
