Really? On what experience do you assert these facts? If anybody anywhere in the U.S. does two HD channels in one 8-VSB mux, I have yet to hear of it. HD or not. The configurations you mention do not include (until this fall) any situations where both nets are HD. That might be why they "can" do it. I'm just starting with analyzing transport streams, but KPBS-DT San Diego uses 68% of it's capacity to do one HD channel, and 20% of for a SDTV channel. NO SPORTS (PBS). With, 8.6% null packets. NO way could they do two HDTVs in that channel. Of course, it's not too difficult to down res a HDTV contribution stream to a SDTV emission stream.

This is the "mini-utility" idea, in which individual DTT stations put together their own mix of prgramming. I like it. > So the question is: What happens when both sub-channels want to go HD? Depends. If the HD programming is not sports, it should work well enough with two HD streams. If one is a sports program, the other will have to be SD, most likely.
