More from Bendov paper.
"As outlined in this paper, television broadcasting would derive significant benefits from the transition to software-defined DTTV and from the assignment of contiguous blocks of channels in each market. Not the least of the benefits is avoidance of interference from other unlicensed and licensed transmitters.
It would be better to plan ahead for this transition. It is likely that the viewers of OTA TV in the US will continue to migrate to cable and other TV program distributors unless the broadcasting community shifts from reliance on "dumb" TV sets tethered to rooftop antennas and inefficient bandwidth usage. Broadcasters could grow the number of OTA viewers by embracing new technical and business models. This paper addresses aspects of a new technical model that would allow for new business opportunities.
Distributed on-channel transmission could play a critical role in the transition to software-defined DTTV. As S2Rx receivers become available, the modulation of distributed on-channel transmitters would be switched from 8-VSB to COFDM. The main transmitter, using 8-VSB modulation, will continue to serve all legacy receivers. Meanwhile, switching to COFDM modulation will significantly increase the quality of service in areas not covered by the main 8-VSB transmitter and create entirely new service for mobile DTTV users. "
First the FCC proposes interfering new uses of the spectrum and then solutions are proposed that further demarcate broadcasters.
At least there is a "COFDM" in this vision. Sounds good but wouln't it be a lot easier to just switch to or allow a better modulation? This sounds like a political and implementaion nightmare.
