I dare say some transmission savings could potentially be made on Freeview by coverting PSB1 to DVB-T2, with nation only variations. Then moving all their channels except BBC1 from PSB3 to PSB1. This would then enable them to cease SD transmissions and in 2026 potentially not renew PSB3.

There may also be some transmission savings to be had by removing radio channels from Satellite/Cable/Freeview, and promoting the Sounds app instead on those platforms.

Presumably if lower it'll also ensure CBBC and BBC Four linear channels, with the equivalent of FAST channels replacing them.

I think the BBC have already said they intend to give up one mux (in 2026 I think) which would presumably see all channels switch to HD only - but you never know with Freeview.

Ideally that move would see ITV/C4 take the four BBC HD slots on the current HD mux, but even more ideal would be that their combined mux is upgraded too so they can offer all their main channels in HD.   It would be a decade later than it should have happened but better late than never.
