I guess therel has to be mux kit for each region producing PSB 3, so it's just a case of getting a feed of BBC 1 HD with upscaled local news inserted to that kit.
Would that require the regional studios to have a sustaining HD feed or could the regional opt switch (or mixer GPIs like the old system for digital) trigger a router at the coding and mux centre to switch the BBC one HD input to upscaled (regional) BBC One SD?
Or is the main issue BBC politics and that it couldn't be done on satellite yet?
There's nothing difficult technically, just buy more codecs, upgrade distribution and contribution to and from the English regions to HD circuits, buy some upscallers for the ERs that are still SD, and provide all the associated monitoring and 'glue' at the CCM centres. It's just a case of money, THAT's the primary problem !
Yes - and it is very difficult to justify spending money to upgrade BBC One HD to broadcast SD upscaled content (only Plymouth, Salford and London originate in HD)...
Viewers shouldn't have to change the channel in order to see regional programming. It should be just available on the HD channel, even if it isn't in HD.
