As subchannels to an existing network affiliate's main channel, yes absolutely! The main network signal pays the bills, and the subchannel revenue is gravy. But for a stand-alone new station constructed from the ground up expecting to live off of a 5 SD channel multiplex, I seriously doubt it. For 4 such stations to make a go of it (in order to reach the Freeview number of offerings), almost impossible. > And as cable systems have shown, supporting more channels is > possible even when many of these additional channels are not > in very high demand. Those additional channels are supported by a dual revenue stream: ad sales and subscription. Your local cable company pays the cable channel per subscriber, you know. > If the attempt being made by USDTV and others is to convert > OTA TV into a subsription service, I will almost guarantee > that it will fail.

Freeview is all SD, and in 8 MHz channels, so the number of services per "channel" is much greater than here.. The John Golitsis' and Doug McDonalds of the world are demanding HD 24/7, which limits the number of bits available for USDTV and a Freeview like service to coexist in the same market. USDTV is destined to fail, simply because in addition to having to purchase the transmission capacity, they have to subsidize the STBs being sold at Wal-Mart as well. When they go down in flames in 2 years, then maybe a Freeview like service will rise out of their ashes.
