As Howard Hughes said (or at least purportedly in Scorsese's "Aviator"), this may be “The wave of the future. Wave of the future. The wave of ..."
With reallocation and crunching of the spectrum such cramming of additional streams into the 6 MHz spectrum may be what's around the corner and perhaps inevitable. At least it might mollify Julius Genachowski's (he of the FCC) concern about what he labels "empty boxcars".
Not far from my location, KXII has been doing statmuxing with CBS on 12-1 at 1080i, MyN on 12-2 at 480i and Fox on 12-3 at 720p. Being a big football fan, I watch KXII a lot in the fall since their feeds are occasionally different than the local D/FW stations. Even with the high motion of football simultaneous on 12-1 and 12-3, it looks very good. Like Wheeling-Steubenville, Sherman-Denison is essentially a two station market, spanning two states. Those two stations hereabouts provide the Big 4 networks and the 2 netlets of MyN and CW.
Drifting a bit from the core topic. I've often wondered why WTOV and WTRF never settled on a common site (a la Parma) to provide service to both cities when DTV was in the planning stages. Given the terrain challenges of the Ohio Valley, a single site would have at least made aiming less of a chore. I'd guess that Windsor Heights would have provided service to both cities. But I'm sure the economic realities were such that using the longtime, existing structures played heavily into any decision. And, unless I'm mistaken, OTA just isn't very big in that area.
