What is DTV?
Digital
Television defined
Digital Television
(DTV) is an exciting new digital broadcast standard that will
provide vastly improved picture and sound quality compared to
current NTSC (National Television Standards Committee) analog
technology. DTV includes both single channel High Definition Television
(HDTV) and multiple channel Standard Definition Television (SDTV).
DTV will eventually replace analog television and will enable
broadcasters to send a choice of more varied information over
the airwaves, cable and satellite, including:
- More detailed
pictures
- Clearer images,
without ghosts or snow
- Dolby Digital
CD-quality sound (6 speaker channels)
- Wide screen pictures,
like the movie theater
- On-screen data
(text and graphics)
Both HDTV and SDTV
will offer the exciting experiences of clearer, more detailed
digital video and audio than today’s NTSC.
Broadcast standards
Broadcasters are free to meet your viewing needs. They may
choose the type and number of signals they transmit within their
allotted bandwidth (6 MHz) and transmission rate (19.3 Mpbs).
Depending on the features of your DTV receiver, a few of the benefits
you will experience are:
- Up to four SDTV
programs broadcast from one TV station simultaneously. These
pictures will be clearer than NTSC, free of interference like
snow, but not as detailed as HDTV
- On-screen data,
such as educational materials, or team statistics during a sports
program
- Pay-Per-View movies
and Premium channels, as on today’s satellite TV and some cable
TV systems
- Access to web sites
related to the program you’re watching
- Shopping using your
remote control to make your choices
