Which HD standard will be adopted?
dodrade
29-10-2006
I have been considering buying an HD ready TV, and know that HD ready sets show 720 and 1080i, but I have read reports suggesting that 1080p may actually be a feasible broadcast standard after all. The technology is still in its infancy, could it be possible that by the time most people adopt HDTV 1080p will have become the definitive HD standard and that current HD ready TV's will be outmoded or useless?

Also, is it really possible to tell the difference between 1080i and 1080p?

and how do standard definition broadcasts look on a HD ready TV?

I doubt 1080p will be broadcast in a time frame that makes a 1280*720/1366*768 resolution display a bad buy. If you can afford and want a 50" plus screen then by all means get a 1920*1080 panel which accepts 1080p source material but none of the HD Ready displays will become useless.

The difference would depend upon the display, after all if you are watching on a 1280*720 32" LCD then there probably isn't a huge benefit either way especially with film based (24p) content. However supplying a progressive source (streamed off DVD) is preferrable to allowing the TV's own de-interlacer to do the job.
SD broadcasts vary from very good to awful on a CRT so the same applies to a flat HD panel, although the overall spread is pushed down from good to god awful

Ask yourself exactly why you want to spend a premium on a HD display right now, then think about the actual small print

I am holding off upgrading for the time being. Very happy with Sky HD 1080i on a 768 display.

Keeping my eye on HD DVD/Blu-ray, 1080p displays, HDMI 1.3.

Won't be making a move until the all the above have become more established. Probably 2nd/3rd gen releases.

Can't see it being that long, months not years.

One site has the Panasonic PF9 (1920x1080 - HDMI 1.3) release as early as Oct/Nov.

Of course 1080p is going to be the next progression in technology. It will become the standard, and Jarrak you can buy 40" tv's which are FULL hd... You might as well buy a 1080p now because otherwise your just buying outdated technology...

1080p may well be used by devices where the media is in close proximity to the telly (so games consoles and HD/BluRay players) but it's a tight enough squeeze for the broadcasters (whether it be satellite or terrestrial) to find room for 720p or 1080i streams let alone needing even MORE bandwidth for 1080p. Perhaps the cable companies are the only ones, using optical for delivery, to have the necessary bandwidth available?

I guess it'll depend on what HD content you expect to be using most on a telly as to whether it's worth waiting for 1080p comatability. But if it's mainly "broadcast" then I wouldn't hold my breath.

Yes, 1080p displays are available now, but at a premium. 1080p broadcasting is years away.

If you have no interest in HD DVD/Blu-ray, and you are only interested in broadcast (Sky/TV Drive) HD, why pay over the odds for a 1080p display when 768 will display 1080i perfectly well.

I have heard there is very little noticeable difference showing 1080i on a display capable of 1080p compared to one that's 768, in my opinion it's not worth paying double the price for something that will never be used to it's full potential.

Tommy i wouldn't say you pay over the odds? What do you think they cost £4000 because they don't....

You are correct, they are nearer £6k

Pioneer PDP5000EX for example.

I will be putting off buying an HDtv until HDMI 1.3, can't really see why its worth buying one without it until then.

Or Sony, Sharp 46" LCDs £2,000, smaller ones even cheaper.

At IBC this year I saw a demo using SuperHD, 4kx2.5k approx, with 22.2 sound, so 1080P is probably not the end of the road either, though whether this will ever get to the consumer in our lifetime.....
I think 1080p will eventually be adopted. There is some evidence from the EBU that at the same bit rate 1080p looks better than 1080i as the interlace compression artefacts not present.

Just because a TV supports HDMI 1.3 interface doesn't mean it will be any better than one that doesn't, it could support the interface but not handle the extra colour precision etc.

You need to look at the TV rather than just use whether it has HDMI 1.3 or not.

I think maybe you've misunderstood them. Nothing from the EBU that I've seen suggests this - do you have a link?

They often like to say p is better than i, but they mean 720p vs 1080i.

1080p50 is double the raw bitrate of 1080i. It may be that the encoded bitrate doesn't need to be double, but it won't be less - just less than double!

Cheers,
David.

I was talking today to a guy who's up here doing OBs for SKy..he said that they won't do HD for a year yet as they're waiting to see which system is the best!

Actually it will, at least better than one without.

However, HDMI 1.3 will not suddenly make a TV better than comparing a poor, say LCD with HDMI 1.3 with a really good LCD without.

i will not use HDMI until forced to do so by implementation of HDCP

imo it offers nothing in terms of pq whatever - and the audio suffers from 'jitters'

it surprises me that people think HDMI was introduced to offer 'us' better pq - it was not - its a copyright protection system forced on to us by film studios!

That is correct, HDMI interface is purely for copyright protection, without it, it is alleged that movie studios and TV companies will use it to prevent copying of high definition content, either by restricting it completely or reducing the quality of the output to 480i to non HDMI devices, this restriction is not likely to be implemented immediately.

It is possible to use traditional analogue connectors for HD, although DVI/HDMI are likely to be the most common connections on the back of HD AV kit.
