Press Release Body = There are three key differences between HDTV and what\'s become
known as standard definition TV ie regular NTSC, PAL or SECAM. The three differences
are; an increase in picture resolution, 16:9 widescreen as standard, and the ability
to support multi-channel audio such as Dolby Digital.

HDTV stands for High Definition Television.

The most important aspect of HDTV, and the one which gives it its name is the
increased resolution. Standard definition NTSC broadcasts have 525 horizontal lines,
and PAL broadcasts are slightly better at 625 lines. In both these systems however,
the actual number of lines used to display the picture, known as the active lines,
is fewer than that. In addition, both PAL and NTSC systems are interlaced, that is,
each frame is spit into two fields, one field is the odd-numbered lines and the
other is the even lines. Each frame is displayed alternately and our brain puts them
together to create a complete image of each frame. This has an adverse affect on
picture quality.

HDTV is broadcast in one of two formats; 720p and 1080i. The numbers refer to the
number of lines of vertical resolution and the letters refer to whether the signal
is progressive scan, \'p\', or interlaced, \'i\'. Progressive scan means that each frame
is shown in its entirety, rather than being split into fields. Both systems are
significantly better quality than either PAL or NTSC broadcasts.

HDTV uses 16:9 widescreen as is its aspect ratio so widescreen pictures are
transmitted properly and not letterboxed or panned and scanned. Dolby Digital
multi-channel sound can be broadcast as part of an HDTV signal, so if you have a
surround sound speaker set-up you can use it to listen to TV rather than just DVDs.

Currently HDTV is widespread in Japan and is becoming commonplace in the US, with
most major networks distributing HDTV versions of their popular content. The 2005
Superbowl led to a large increase in the demand for Fox Sports HDTV and cable
companies scrambled to add it to their offering in the run up to the game. In
Autralia, HDTV uptake was sluggish initially but has increased significantly since
2003.

The situation in Europe is not so bright. There is only one company broadcasting
HDTV in the whole of Europe, Euro1080, and it has only two HDTV channels, both in
the 1080i format. Euro1080HDe shows major cultural and sporting events to cinemas
and clubs around Europe, while HD1 broadcasts sports, opera, rock music, and
lifestyle programs via satellite to homes in Europe. UK satellite broadcaster, Sky,
which is owned by Fox proprieter Rupert Murdoch, has announced plans to broadcast
some HDTV content in 2006. The BBC has also made noises about broadcasting HDTV
programs (it already films some programs in HD format).
