There is no question that HDTV is much better than the analogue system we’ve been used to.
Vastly Superior Picture Performance. Broadcasters are now be able to transmit pictures with a quality far superior to today’s NTSC television system or any other picture source currently available (e.g. VCR, DVD and Laser Disc).
New Wide screen Format. HDTV provides for a wide screen presentation similar to what you see in movie theatres. The new screen has a width-to-height (or aspect) ratio of 16:9 compared to today’s 4:3 width-to-height ratio on conventional television sets.
Wider Aspect Ratio. See the illustration below.
Clearer Pictures. HDTV eliminates “snow” and ghosting.
Better Color. HDTV delivers exceptionally vivid colors – including subtle purples and reds – and eliminates any bleeding of colors at the edges…
Multi-Channel Digital Sound Quality. HDTV provides highly advanced Dolby Digital Audio, also known as AC3, with 5.1 discrete audio channels.
Future Possibilities. HDTV uses a high bit-rate channel, which will mean broadcasters will be capable of transmitting new value-added services, such as Interactive TV, to consumers in the near future.
