HDTV: An Introduction
By: Kenny Hemphill

HDTV stands for High Definition Television, and if you live in the USA, Australia, or

Japan you may already have experienced it. 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.

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

multichannel 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.

To receive an HDTV broadcast you need either a TV with a built-in HDTV tuner or a

HDTV receiver

which can pick-up off the air HDTV channels, or cable or satellite HDTV like. You

also need to live in are where HDTV channels are broadcast or distributed by cable

or satellite.

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).

However, it will be a while before HDTV in Europe catches up with the rest of the

world. The controversy created by the confirmation of plans by the UK government

to start switching off analogue transmitters in 2008 showed how many people have

yet to make the switch to DVB-T. That will be used as an argument to show that

there is no appetite in the UK for another major change in TV broadcasting -

particularly as most people think they already have 'digital TV' in the form of DVB-T.

Given that television was invented by a Briton, and Europe led the way with PAL for

so long, this is a rather sorry state of affairs.
