Who/what is driving digital broadcasting, worldwide, yet?
If you wander the wilds of VietNam at night, the glow of television outlines the windows of isolated 'houses' where even the most impressive Yagi antenna might pull in one or two channels - if thee wind is blowing the right way.
In the cities the maximum OTA (Over The Air) channels might be 15, Cable is good for up to 150 or so.
In Laos and Kampuchea (Cambodia) the situation is similar. As for radio broadcasting we have FM and short-wave (for the mountains in the northwest). The rabid religious broadcasters, in the Phillipines, us 500KW transmitters on Medium Wave AM - they don't seem to realise we have no AM sets in China or Indochina!
YET the governments of these countries has been persuaded, by ASIAN, to go digital. So poor people who might make $700/annum as farmers are going to have to upgrade. It can't be spectrum, VietNam has border to border to coast cell coverage, with masses of unoccupied spectrum.
I agree with other posters, DAB is a retrograde step for quality, so who other than Chinese and Korean manufacturers are to gain?
