The size could obviously be reduced yes, but the quality could also be improved, BBCHD didn't look great at 17.8mbps MPEG2, now virgin have reduced it to 16.5mbps MPEG2 and its really looking poor now, it needs to be around 20mbps but with mpeg4 this could be reduced alot and still give us higher quality than we currently have.

You could also increase the quality and reduce the size of the SD channels which are blocky as HELL, you could also give us 720x576i for each channel with the bandwidth saved instead of giving us crappy 544x576i for some channels.

As far as i'm aware virgin have given customers boxes with MPEG2+MPEG4 support for the past few years, there can't be that many that would require a new mpeg4 supporting box, this cost of upgrading boxes would be ofset by the reduced bandwidth costs and viewers would have a much better picture.

There is no inherent quality difference between MPEG2 and MPEG4 only compression ratio.
If you want to see MPEG2 and MPEG4 struggle try watching a gardening program, all those leaves kill the compression!

If you know what to look for you will see it, if you don't I suggest you don't find out any more as once you notice it you will forever see it.

It's not great on my Toshiba 42". Try increasing the bitrate to 20mbps+ at your HQ and take a screenshot and compare it to 16.5mbps, the difference will be significant. Get them to make it 14mbps MPEG4 and your jaw will drop to the ground at how good it would look.

Reducing the bitrate from 17.8mbps to 16.5mbps made the problem or substandard quality even worse.

Sky use 16-18mbps mpeg4 for Sky Sport HD, thats what quality really looks like!

i think we all know it will be launched this year, virgin would lose alot of customers if they didn't. The virgin employee said it would be in time for the world cup a few pages back. I wouldn't mind knowing a more accurate date though.

Am I missing something, that link to your blog MB seems to end mid sentence, or is the posting supposed to say "Nothing has been announced yet?"

I think DF knows what he's talking about.

Doesn't nothing has been announced yet simply mean we all know it is coming soon but nothing has been said by VM?

Try 14mbps.
Sky1 only gets 12mbps, and the sky movie channels use between 8-12mbps.

Sky skimp on bandwidth more than VM do.

their response:

"There's no information I can give you at the moment but we appreciate the feedback :) ST"

I'm not sure what ST means? maybe sincere thanks??

Early Blu Ray discs (like Mission Impossible 2) used MPEG 2 to deliver a great picture. If you throw enough bandwidth at it, MPEG 2 can do a job.

Given the great analogue switch-off (which will free up loads of bandwidth anyway), I don't think VM are in that much of a rush to use MPEG 2.
