    Is the PQ going to get worse on SD channels?

    Because the more channels they have on a mux the worse the picture gets.

    Are channel bit rates going to go even lower?

    What and how many channels are coming to Satellite?
    There are always a few that launch every year but no huge jump since SKY bought digital satellite to the mass market and then a couple of years later when ITV put a load of channels on. The introduction of HD meant 5(I think) transponders went online almost at the same time but they were brand new so made no difference to any existing service.



    There are currently 4 satellites that supply the channels that you see on the SKY EPG and they can have upto 32 transponders each (muxes in DTT terms) so that explains why there is so much capacity currently used. A new satellite is being moved to serve the UK and that will supply a lot of the new capacity we will see in the next year with ITV buying more space (for their HD and regional output) plus I assume FXHD plus many others.

    Since whole transponders can be bought by a broadcaster what others do makes not difference to their bitrate and other smaller broadcasters buy a set amount of bandwidth and again what others do isn't a factor.
    Taking ITV as an example, they only reason there bitrate/res would be reduced if they chose to do so.
