The Mux operated by BBC FTV ltd is PSB 3 which was a Commercial mux operated by on/itv Digital
PSB 2 is operated by D3&4 which like PSB1 for the BBC was gifted in 1998

So how about a deal done with D3&4/and its owners and c5 to give up PSB3 in its entirity
use the BBC PSB3 equipment for PSB1 (in HD only but with Radio), D3&4 get Arqiva to install new moduators,
BT to just press the button to reconfigure the D3&4 coders (which are fed HD at the moment) to work AVC AAC T2 PSB HD rest SD
and Combined PSBs pay off Arqiva for 9 years of unused mux ........
PSB3 has no resale value ... who would want to emit on the most expensive platform in the UK
Remember it took a well funded PSB three requests before they bought space on it!
but the CMA may say something wrt COM4 and like Motorola on ESN - COM 5 and COM 6
..... but we are out of the EU so they cannot intervene on state aid grounds
The Vaizey plan just 10+ years late!

All a bit tongue in cheek - but it highlights the issues....

But if you keep PSB1 and PSB3 with current content do you have only UK/National BBC SD
it saves a vast lot of replacement coders - !!!! like 100 .. a great price for being regional
(Existing are old and hardware not Software like PSB2 and 3)
and does the deal with BT allows itv to do likewise ... when they reagionalise their feeds to PSB3

Post 2035 one may hope that Mobile Telcos will have had 6 year after 3GPP issues the spec
- so that 5G media broadcast can be enabled ....
But the commercails and idealy use of common carrier.. Make this very complex ...
But by then the ESN may opetering so there will be at least one Telco with UK wide coverage
but how many channels to be emitted???
....... which is the "Being digital ready (first??)" question....
