Been discussing this with those in the know on Twitter in the last week, following the transfer of More 4+1 off of the BBC 'B' Mux in the last few days, enough space seems to be available for an additional HD channel on BBC 'B' going forward. The fairly widescale discontinuing of Muxes 7 and 8 in many areas as a result of the 700MHz clearance programme opens the possibility of BBC Four HD / CBeebies HD (or another related PSB service) appearing on every transmitter in the Country in the not too distant future.

We can hope, bur PSB3/BBCB is not, and never has been for exclusive land grab by the BBC. You're right though, for various conspiring issues, COM7/8 are on death row, and will be gone at or before June 2022. However, I don't think BBC4 as a linear channel has much of a secure future

They've largely achieved it in France where most channels are in HD on TNT unlike the UK where we're stuck with 544x576 channels crammed on most muxes. Even the local channels such as BFM Paris and IDF1 in Paris are HD.

A plan should have been in place from the launch of the COM7/8 muxes considering they were only ever meant to be temporary. Instead they're about to be turned off and we're in the same position as we were a decade ago, just with more low quality SD channels crammed in.

The aim should be for a gradual switch of the remaining 5 SD muxes to HD - or T2 to be more specific, as most channels would likely remain SD. In the short term we'd have a reverse of what we have now with one remaining SD mux to accomodate the PSB channels, though that shouldn't have to hang around very long now. France basically achieved HD by just having a strict switchover - IIRC the SD service was closed one day and replaced by the HD service the next.
I preferred the internet when it had a sense of humour.

There was a proposal from Ed Vaizey in 2011/12
Mandation of the PSB to emit HD only on all Platforms
the DTT conversion co-timed withe the frequency change fir 700 MHz clearance
but as the minister I don’t think that the political reaction would have been that popular !

Sadly the temporary muxes have not met their objectives
So I feel that the current migration to SFN in the middle of the mobile band is a waste of government money which could be better employed by making the existing (PSB) muxes emit more efficiently .

There are many public policy / commercial effects if reducing the number of PSB mux to two (18 nations / regional and say 6 national ones ...)
like who will pay arqiva to broadcast nothing !
And who are the two mux operators

I read today that a religious channel is taking the spare bandwidth on PSB3

The Angus Transimmter has switched off CH48, CH49, CH53, CH54, CH57, CH58, CH60 as part of the 700Mhz clearance at 0:05am


Was there any publicity? Seems to me both DUK and the broadcasters have more or less given up mentioning these major engineering events, which is odd given everybody switching on their telly in the area this morning will be greeted with a blank screen, (even those who have auto tuning tellies)
