The DTT mux does not have Teletext subtitles in it as was required for analogue ..... but the DSAT does for Sky boxes ... hence the use of a DSAT feed .
Of course! That makes complete sense now!
The regions are fed ST 2022-6 SDI over IP both to and from the regional opt switch and then coded and muxed and then given to Arqiva at ASI who I think use ST2022-2 IP to the transmitter
Ah - when did the 9Mbs MPEG2 BBC One network distribution become deprecated - was that when coding moved from local DSat and DTT CBR encoders to backhaul for coding and mux, or was it when the Energis/C&W/Vodafone connectivity was replaced by BT? (The 2022-6/-2 stuff makes me think the latter?)
