What Is HDTV?
HDTV describes a high definition TV picture that offers a quality of
picture about four times better than the one you will currently receive.
HDTV pictures are broadcast at a widescreen ratio of 16:9 and take up many
more active rows than a Standard Definition TV (SDTV) picture.
TVs in Europe that are capable are displaying HDTV have the "HD Ready"
logo on them. This means that they have a minimum of 720 horizontal lines in
their display, and possibly 1080 horizontal lines.
HDTV in the UK is broadcast digitally but is only available through
Digital Satellite and Cable - not through Freeview at the moment, although
this might change following the Analogue Switch-off.
