[QUOTE="spiney, post: 179814, member: 192438"] er, I'm really confused now, but anyway everybody knows I'm a tedius windbag by now, so "super-pedant mode on": VSB was tried and tested, using known adaptive filter techniques, whereas COFDM was new, and ridiculous (and unfounded) claims were made for it! Plus, the recievers were originally much more expensive, thanks to the extra processing stages and chipsets needed. On Digital finally failed - at least in part - because COFDM isn't as good for tv as originally claimed (it's great for wi fi routers, but that's different!). Something said quite publicly by the disgruntled ex chairman, but largely ignored in news reports. As it's turned out, VSB is actually slightly better, although there isn't that much in it! ( [URL="http://en.wikipedia.org/wiki/8VSB"]http://en.wikipedia.org/wiki/8VSB[/URL] ; googling "atsc cofdm" will get many articles with various viewpoints!) With mpeg, i think 12 channels for price of one is probably a slight exaggeration! [/QUOTE]
