We were talking DVB-T COFDM. Have no interest in having the highest
power, want the best reception and SFN/repeater capability for mobile
reception at high bit rates. DTMB would be the best today I believe
and close to what DVB-T2 will be.

Would have no interest in anything 8-VSB/A-VSB. Reception problems,
high power usage for receivers, mobile A-VSB is a data hog, little
support or interest from CE companies or current broadcasters, no
breadth of receive devices etc. Incredibly if trying to use 8-VSB you
would be a pioneer.

Rather be tied to the Chinese standard which will be used in the
biggest OTA market in the world and where most TV stuff will be made
in the future anyway. And where every CE manufacturer in the world is
scrambling to make receive devices for as I type.
