Broadcasters will soon realize that they can deliver a minimal program in SD to satisfy the FCC requirement for MPEG2 while delivering the rest of their offering in MPEG4 whether it is HD, ED or SD. The cable companies must carry the SD channel and will pay to carry the MPEG4 content if it is good programming and whether it is HD, ED or SD. If broadcasters were really smart they will withhold the best programming altogether to increase the value of their OTA spectrum. There is no "main HDTV channel" except in the diehard imaginations of Luddites afraid of advanced tech that would allow mobile reception. Bob Miller Doug McDonald wrote: >Of course not.
