Now weve got tdp sports on four different TPs, but whats the use of this?
It's just because these feeds are mainly for the terrestrial transmitters in Spain (the TDT SAT system is a nice extra possibility!). The system they use allows them to re-assemble the ~20Mbps DVB-T mux from the PID containing the relevant regional version of La 1 HD + RNE/RNE Radio 5, and the common PID containing La 2 HD/24h HD/TDP HD, without any re-encoding. It's easier to have everything required in each region on one frequency together. A couple of the regions (Madrid, Catalonia, Canary Islands) have a full mux instead of the two parts, for Catalonia and the Canaries at least this is because there is sometimes regional programming on La 2 and even 24h, so a common version isn't suitable for them.
Only checked the MPE muxes here but everything nicely in 1080i resolution now, much better than before!
