    Can we expect to get a higher bitrate on Freeview when the switch over takes place?

    I'd be happy with a stable picture in the first place. At this point in time for me, digital tv tranmitted in ALL its forms has been a huge disappointment; so much so I have all but stopped watching. :thumbsdow I do believe there are big changes soon in my area (northwest) including an increase in transmitter power but ill just have to wait and see. I do not expect any improvement in quality just more dross channels.

    No quite the reverse, removing a Mux for HD will reduce bandwidth so bit rates will have to be reduced, hopefully more advanced encoders will help. A change for Mux 1 to 8K mode will allow more channels to be shoehorned onto this mux at dso

    Rather dodgy headline writing there for the sake of exaggeration - the new Mux 1 will have 33% less capacity than the current Mux 1 and B pair, but it won't be carrying as many channels.

    Certainly a reduction, but not 33%.

    No, the 8k mode will do nothing, but make the signal better for SFN's and more robust to impulse noise only. It will not allow higher bit-rates - Period.

    The much higher power at DSO will both enable the 64-QAM mode (adding 6 Mbit/sec) and make the signal much more robust.

    But in this case the advise is wrong, very, very WRONG.

    With the new MPEG-2 encoders and stat-muxing that the BBC is/will be using plus moving one BBC channel to MUX2/PSB-2, you may end up with better picture quality.
    The total SD bit-rate are 120 Mbps on 6 muxes pre-DSO. The SD bit-rate will be 120 Mbps on 5 muxes post-DSO.

    On top of this comes the 36 Mpbs for the PSB-3 HD mux post-DSO.
