A Brief Look at Broadcast and Digital Television

Broadcast television is a traditional way of watching TV programs simply by installing an antenna. This is called analog TV.In recent years, many countries have begun to mandate a transition from analog to digital television. Digital TV provides noise-free, high-definition picture quality, Dolby AC-3 sound effects, and a handy EPG (electronic program guide). And the 16:9 video format gives a wider view than the traditional 4:3 format. Many TV broadcasters are now delivering digital TV programs, so switching to a digital HDTV receiver now makes good sense.

Digital TV programs are broadcast on both VHF and UHF frequency bands. Traditional analog TV uses one frequency channel to carry a single station's program. With digital TV, one frequency channel can carry up to four station programs. For example, analog channel CBS 2 may have become 2-1, 2-2, etc. when broadcast in digital TV. Channel 2 is the maj or channel and channel -1, -2, etc. are the sub-channels.

Digital TV signals are transmitted in either free-to-air (FTA) or pay-per- view (PPV) mode. FTA programs are received free with an MPEG 2-ATSC compliant digital receiver, such as the HDTV-ST. PPV programs can be received only by paying an access fee to the broadcaster and by using a digital receiver incorporating a compatible conditional access system.

In addition, the HDTV-ST lets you watch HDTV, EDTV, and SDTV digital TV programs.

*HDTV stands for High Definition Television; the common video formats are "1920 x 1080 interlaced" and "1280 x 720 progressive".

*EDTV stands for Enhanced Definition Television; the common video format is "720 x 480 progressive".

*SDTV stands for Standard Definition Television; the common video format is "720 x 480 interlaced".
