For insomniacs and early birds, don't be alarmed by a blank screen on #bbc #hd @ c.4.30am - we're doing some tests on the channel

Trying to fix the problems with the 25Hz and 50Hz switching?

more seems Satellite related ....

Advance warning for you night owls: there's technical testing to BBC satellite platform from 0430 -0500 tmrw, so no #BBCHD at that time.

It makes little difference as it would only be showing the Preview anyway.

Then again, the preview is quite good to watch if there's nothing on. Wink

Changing over to DVB-S2, perhaps? I've heard mutterings that that should be happening round about now.
(of course, that would affect everything on the mux, not just BBC HD)

On Freeview HD on the BBC HD channel this morning they tested the sound channels - though I don't know if they normally do that.

It wasn't related to the I/P issue (from Danielle Nagler in answer to my DM to her.)

They do that test and they have the 1080 lines testcard alternating at each hour whilst BBC HD Preview is on air.

Anyone found out what they tested or are they trying to find ways of dropping the bitrate further on these (hardly pin sharp) BBC HD channels.
