mike123abc said:Of course Rainbow-1 cannot do it alone, this causes a problem at Dish. Some of the larger DMAs (Like NY and LA) would have too many channels for a spot unless they get to do 3 channels/TP. Also adjacent spots (especially in the NE) would be TP starved if they are all used up on NY/LA. Of course if a bunch of space frees up on 61.5 by them moving all the internationals to 121 and all the SD LILs off to E10, then perhaps they could use E3 CONUS for the major stations and put the rest on the spots (like they do now for NY/LA, have the majors on CONUS and the rest on spots).
Don't forget about the added capability from MPEG-4 which I believe would allow up to about 9 HD channels per TP. I also believe that the new SHREVA rules will drive the need to have HD major network locals for a large city from each time zone on CONUS TPs i.e., N.Y., Chicago, Denver and L.A.
By the way, I am working on a rough estimate of the power capabilities of Rainbow-1 based on ancillary data. This should give a ballpark estimate of how many TPs could be used at once. I will post it in a new thread in the Dish Forum since I believe it is more appropriate there.
