It doesn’t matter so much if the studio isn’t HD yet. Having everything in one place without having to change channel would be a bonus. Obviously infrastructure would need to be in place for this, but where are the HD muxes encoded? ISTR it’s done in London for all regions. If that’s the case would there be any need for new equipment in the region at all if the regional output remains SD?
The HD channels are encoded at a couple of locations.
Yes to provide HD regions would require new encode chains for each of them (so 4 for each, 2 in each site I assume) plus reconfiguring the HD mux. I would assume that the MUX would need a change to its distribution too as there are more BBC regions than there are ITV HD regions
