Digital TV (DTV) is a new television system that provides over-the-air digital signals. The resulting picture is up to five times sharper than that of today's sets, with CD-quality sound. There are two types of DTV - high definition television (HDTV) and standard definition television (SDTV).
HDTV
HDTV is programming broadcast in wide screen aspect ratios, the highest resolution formats, and Dolby® Digital audio. It is the finest signal available through DTV.
SDTV
SDTV is also a digital broadcast. It will provide a better picture with higher resolution and richer colors than today's signals.
Why are their two types of signals? The different signals will give broadcasters flexibility when deciding how to use their digital channels. For example, sporting events, movies, and primetime programming will likely be shown in HDTV, while daytime programming, news and the like will probably be shown in SDTV.
Broadcasters will have the option of showing several SDTV programs or one or two HDTV programs, all with a single DTV channel.
