Help/Advice...Screen message displayed permanently on both Channels, i.e. ITV 1 HD (103) & Channel 4 HD (104).

Same problem after 10 pm tonight BUT it's also affecting channel 46 (5SELECT) which is also being broadcast on UHF channel 35 so I suppose it could be affecting many channels!

The quick rewind trick sorted it as it only affects live TV.

Channel 57 also affected - U&Eden.

being broadcast on UHF channel 35

What would be of more relevance is the name of the multiplex. 5Select is broadcast on BBC B, as are U&Eden, ITV1HD, & Channel4HD. BBC B is a DVB-T2 mux, and (tellingly) we are aware of other mucking about on DVB-T2.

Are we? You might be. I'm not.
The Freeview planned engineering page is very unhelpful. Every transmitter appears to be on the list, and has been for quite a while. Either screen goes blank or pixelation and no mention of multiplex.

Are we?

Perhaps not. After further reflection, I think it was the creeping of T2 codecs onto T muxes.

There is no such thing as a T2 codec. Codecs and modulation are completely different things.

You can't go upsetting the snowflakes with scary technical detail. They might wet themselves.

So where are you supposed to get the technical information that we might find useful?

Technically correct. I understood what was meant. The creeping use of MPEG-4 (instead of MPEG-2) on DVB-T multiplexes. MPEG-4 being commonplace on UK DVB-T2.
