Cool. I doubt it'll show anything that isn't on one of the 24 BBC Olympics HD channels but it should be a great addition for sports fans with Freeview.

I hope they use this 301 HD channel for Wimbledon too - they can have 3 simultaneous HD matches or they can broadcast 3D on BBC HD whilst having two HD matches. No point in having 301 HD there but not being used!

Having 5 1920x1080i channels on Freeview for a while will be nice.

I think the 1920x1080 is permanent. Previously they only increased one stream res to use 3D. Today they have increased all four and added a new stream as well.

ITV1 HD and Channel 4 HD were already 1920x1080. The fact that they've changed BBC One HD as well as BBC HD does indicate that it might be permanent though.

It was stupid for them to not all be the same resolution though - it was clear that the new encoders could handle 1920x1080i because some channels were using them, so why not all of them? They might be able to up the bit-rate with an FEC change but I bet they won't do that without squeezing in a 6th channel so I think what we have now is the best we're gonna get on Freeview HD.

The BBC answer would be that it is better visual quality running at 1440 as at the DTT bit rates it distorts the input signal less by putting the processing power where it is best used..... until the coder gets more upgrades etc ... (and of course in a normal viewing distance the eye cannot resolve 1920)

Are the BBC HD channels now 1920x1080 permanently even on satellite now?

Only on satellite, only two weeks ago, all four Freeview HD streams were running at 1440x1080.

The BBC have been sticking to that argument and preventing discussion in its forums about bitrates and resolutions for some time now.

All I would say is that the competition did not agree and most viewers could see the difference. The Head of HD & 3D resigned.

Occasionally the BBC gets the big topics badly wrong and as it does not know how to admit it's wrong, inverts its own spin. It's about time this was changed.

It seem to recall hearing this but better ask on the right forum.

Are the BBC now finally starting to see sense in the importance of broadcasting HD at 1920x1080i?

I would check but my HTPC isn't on today so can't remotely connect from work.

Yes that's what I've always believed to be true.

Well I'm surprised and obviously happy that all channels are now 1920x1080 although I doubt I'll notice any difference at my viewing distance.

I do hope this is a permanent move.

I think you find that others are driven more by their marketing departments ....
...... and the BBC did show how it is a more faithful representation -
But it may not look like that (unless you have the source material) ...
and the work on "what you can see/ angular acuity" predates the launch of any HD service in the UK...
and I think that there were other attractions outside the BBC for Daniele (and did the job exist in a (pre_) DQF world??).

PS more bits can make worse pictures - because of which tool kit the coder uses ...

We are expecting it to appear on LCN 304 - see http://www.bbc.co.uk/blogs/rogermose...d_for_bbc.html

But surely you are not saying that an encoder tuned for high bitrates will produce a worse picture than one tuned for low bitrates? I'd have thought that having more bandwidth would (when handled appropriately) produce better results every time, wouldn't it?

No, you are thinking in a linear way. More bits of information doesn't necessarily produce a more accurate representation. Nor will it necessarily look subjectively better.

OK, but why not? (Assuming the equipment is optimally adjusted for the available bandwidth.)

Makes sense for the Freeview HD channels to be like this

51 - BBC One HD
52 - BBC HD (soon to be BBC Two HD)
53 - ITV1HD (eng/wal) (STVHD in Sco & UTVHD in NI)
54 - Channel 4 HD (eng/sco)(not Wales....yet)
55 - Extra 5th stream for BBC during Olympics
(poss Channel 5 HD... In future)
56 -
57 - S4C (Wales only)

No the BBC has already said the 5th stream will be LCN304 a simulcast of 301.

Already covered in the DMOL consultation. Likely to be 101 onwards.
