It would seem to me that it would not be woth buying a HD tv yet as I would expect improvments in quality and lower price in a few years time and by then there should be more programes to watch

Has anyone seen HDTV yet? It seems to me that the present system, given a good signal, is already high enough definition. Yet another way of extracting our hard-earned?

I saw HDTV in the US - the difference is quality and clarity of picture is considerable.

If you saw it you would not say "given a good signal, is already high enough definition"

Thanks for yours. I'll wait and see.

There is/was a Sony travelling exhibition which demonstrates HDTV.

I saw it a couple of times in Brighton.

Lets say I won't be rushing out to buy - like I wish I hadn't bought my DAB radio (which is now in a cupboard, unused).

"Lets say I won't be rushing out to buy"

I ama interested to know why becasue as I said above I was very impressed with what I saw in the states.

Not keen because the equipment is very expensive and the improvement in visual and audio quality doesn't justify the extra expense.

I've heard that the version of HDTV that will be broadcast by satellite or terrestrial is a bit over-compressed, so the picture isn't as big an improvement on standard TV as you might think. Still pictures look great, but things blur quite badly during a pan.

There are 3 standards of HDTV:

720p - 1280x720 progressive (60 FPS)
1080i - 1920x1080 interlaced (30 FPS)
1080p - 1920x1080 progressive (60 FPS) (FPS = frames per second)


The vast majority of 'HDTV ready' TVs available today only support the lowest spec of the 3 standards - 720p. This means that when HDTV content is the norm, your TV will be resticted to a significantly smaller resolution and you will not gain the full benefits of HD-TV.
