Short for
Standard Definition Television it
is a type of
digital television operation method which is able to transmit and produce
images which are of a higher quality than standard
analog broadcast. SDTV is
typically a 480i signal - where
480 represents the vertical resolution
and
i represents
interlaced. Digital cable and digital satellite
programming is widely available in SDTV format. While SDTV does not reach near
the quality of HDTV, it is superior over traditional analog television.
