Dan - What I can't understand is why these things that are supposed to be causing hangups with hdtv can't be worked around my declaring them variables. Why not do a tv that can understand both progressive scan and interlacing? Why not make aspect ratio part of the frame headers? I guess I just don't understand why a tv signal can't be modeled after the tcp/ip stack. It would make more sense, and provide expandability for the future. -justinb

>>>There's also the political thing about how all the TV affiliates want to take the big HDTV channel they were given, put a low-def digital signal on a piece of it and use/sell the rest for their own benefit.<<< This I know is true. The gov gave them (not sold them) the bandwidth to do local station hidef, and now that they have it they want to steal it away from hidef and sell it to internet providers, newsfeeds, and all that. Not only should it be taken away from them, they should be punished in some other way, in my opinion. As far as the electronics go, I understand we bludgeoned the Euros and Asians into this standard, which is related to DVD standards on resolution and the like. If this doesn't go ahead the whole TV->DVD->computer transparent graphics production pathway, and all the opportunities for software and interactive TV that promises, is pretty much dead for American companies. I actually saw working TV hardware for this at a NAB/SMPTE conference in '95, BTW, from Kodak, an American company that would like to break into TV production hardware, in which Sony has a near monopoly. The interlace thing is a way to save transmission bandwidth. In hardware, since the graphics processors are so fast now, it's just a hassle. And it creates numerous problems in quality and in making software workable. Totally sucks, and is one of the main reasons for changing the system. Interlace is the reason it's so hard to do small text on TV, otherwise the resolution now would be enough. Anyway, enough bandwidth has been reserved to do full-scan, no interlace (given that the transmission is digital and can be compressed.) What I meant was, where is the FCC on this? Where are the computer manufacturers? The last I knew we delayed the Japanese hidef system and did this system to fend them off from making nearly all TV sets in the future as they have recently in the past. So we produce this technically superior system as a reason why they have to wait. But it seems to me that they are just going to move in on this situation because of the delay. This can't all be happening without any reason at all, can it? Can the local stations really have enough clout to make everybody else involved in the US turn retarded? Chaz
