Yes, most of the broadcasters are simulcasting their main channel in HD and then using the rest of the bandwidth for side channels, often in SD.jsm wrote:Ah, that makes sense. I really dislike the American system, it's just too free-market. DVB-T looks so much better. I'd rather have 80 16:9 channels, plus radio, then 11 HD channels, with no teletext or interactivity.
These side channels are often weather or news services - NBC's stations had 'NBC Weather Plus' until recently and PBS stations have a kids and a documentary channel. Although a channel in one area which has only had CBS and NBC analogue stations has put CBS and Fox onto it's sub channels:

The terrestrial system in the US isn't really the place if you want lots of choice though, cable or the big satellite companies have the channels - just like here
