High Definition Television: A Quick Overview

When you read and hear people talking about hight digital television (HDTV), what they're really talking about is the transmission of pure digital television signals, along with the reception and display of those signals on a digital TV set.

The digital signals might be broadcast over the air or transmitted by a cable or satellite system to your house. In your home, a decoder receives the signal and uses it, in digital form, and feeds it directly into your digital TV set.

There is a class of digital television that is getting a lot of press right now. It is called high-definition television, or HDTV. HDTV is high-resolution digital television (DTV) combined with Dolby Digital surround sound (AC-3). HDTV is the highest DTV resolution in the new breed of televisions, it has created a new set of standards for television sets.

This combination creates a stunning image with stunning sound. HDTV requires new production and transmission equipment at the HDTV stations, as well as new equipment for reception by the consumer. The higher resolution picture is the main selling point for HDTV.

The original impetus for HDTV came from wide-screen movies. Soon after wide-screen was introduced, movie producers discovered that individuals seated in the first few rows enjoyed a level of participation in the action not possible with conventional movies. Evidently, having the screen occupy a great field of view (especially peripherally) significantly increases the sense of "being there."

But since there are so many more scan lines, both the lines themselves and the motion jaggier are much less visible. With a HDTV your DVD's will be a cinematic experience you'll never forget.
