VNSI - Picture goes white - BBC One HD

edz2k9 · 2011-06-22 13:24

Hi All

just a quick bit of info that I came up on when trying to edit BBC HD recordings from MythTV. The BBC broadcast a switch moving from progressive to interlaced on their HD channels, this is evident when you reencode something like Doctor Who into progressive and the end credits jump about.

This happens at GOP boundries as shown here

If this isnt of use please ignore.

Many thanks all!

Also, the issue still exists after the BBC changed their HD channels from DVB-S to DVB-S2.

A quick note...

I've just been watching BBC HD for 2 1/2 hours and haven't experienced the White Screen issue. There has been a change though, it was being broadcast at 1920x1080 rather than 1440x1080, and probably some other stream changes too.

And then ~20 mins of BBC One HD and it goes white...

Just watched the whole of the F1 qualifying on BBC One HD without the white screen.

I'm currently on the latest ODK and running VDR 1.7.21 off the unstable PPA with the xvdr plugin and addon.

Obviously I don't know where the solution has come but wherever it has I'm happy!

Same here, just watched quali in it's entirety without a lockup!!
This is using ODK48 and the current TVHeadend from lars' launchpad page.

So it looks like an XBMC thing rather than a VDR fix. Good work Lars, or maybe the BBC has changed their broadcast somehow.

I've ended up going back to ODK40 due to some buffering issues with ODK48, with ODK40 working much smoother and the white screen issue hasn't appeared today.

Maybe BBC have changed something with their broadcast because I've only ever seen it on BBC Sport broadcasts.
