I'm still new to this, so tell me if I have this wrong. But the way I understand it is, with the new technology, broadcasters will have the option of transmitting a single HDTV show or give the viewer multiple viewing options in standard resolution (SDTV). For example, our CBS affiliate here broadcast the NCAA tournament in SDTV, giving the viewer the option to choose between multiple games to watch on the same channel. (article is here.) Which makes me wonder, what is the incentive for broadcasters to go with HDTV programming rather than multicast? Yeah, you get a "prettier picture" with the HD, but you can sell more advertising with the multicast. Will there really be a day when all I see on my TV is 1080 resolution?
