As far as PSB3 goes …it launching in T2 AVC AAC was a very good move
…frustrated by a full HD (mostly) by the effects of government in not adopting the Vaizey plan
and not keep the LF roughly in line with inflation …. Or increasing it at all .

Your proposal for PSB2 means that it is not carrying any PSB services ….
And I’m sure that BT will not be impressed moving from a fully regionalised mux
to two hand fulls of coders …..even as every one of the coders are HD capable…
…. But Arqiva may like the extra telco and transmitter conversion costs .
This dropping PSB requirements was a major factor in why Vaizey had issues….
But as he said the government can only easily mandate the PSBs to,emit HD only in all platforms

PSB 1 would close tv wise for under the Vaizey plan …..
But if you played about with things …
Its non tv services could be put on PSB3 … which would be the only regionalised mux.
And the only PSB mux….

Having looked at how HD broadcasting could be migrated even before Vaizey ….
It was a great pity that his plan was not carried out with proper funding for theBBC to do it …
Rather relying in the generosity of itv ….
There were /are a lot a variations but the need for probably only 1 PSB mux and it being regional
……plus probably the other muxes being national (pseudo PSB ) and uk wide (entire commercial )
so say about 20 HD services ….

Or as it has taken so long that the BBC policy of regional,HD on IPlayer only
Will be seen as being the right one.

The fact that the UK government did not exploit the band clearance is so silly !
