said by recneps:A single transmitter could provide 20 channels of 1mbps each.
As you're only operating one transmitter, you can also just crank up the power and serve a very large area.
Some of the ATSC stations in Toronto are only a couple kilowatts of power (compared to the megawatt analog stations that they had)
So imagine a full megawatt ATSC transmitter's range..
Because there would be some overhead I doubt that 20 Mpeg-4 subchannels would be practical but a half dozen broadcasters with a subchannel or two each would probably work out. Also MPH is very well designed for distributed transmission (multiple low power transmitters) and could probably cover an area better than with a single large transmitter. MPH should also have fewer receptions problems than regular ATSC.
