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
