Definitions for "Standard Definition Television"
Keywords:  sdtv, ntsc, hdtv, ghosts, interlace
This is the current NTSC standard for television broadcast transmissions.
Offers the ability to transmit four or more standard-quality programs (equivalent to NTSC) instead of HDTV programs, using the same channel. SDTV also incorporates stereo sound plus a wide range of data services. It displays picture and sound without noise, ghosts and interference.
Digitally transmitted SDTV includes 480 line resolution in both interlaced and progressively scanned formats. It offers significant improvement over today's conventional NTSC picture resolution, and is similar to DVD or DBS quality because the digital transmission eliminates snow and ghosts, which can be common with the current NTSC TV format. Also, thanks to digital compression technology, several programs can be transmitted simultaneously within the same channel.
