[opendtv] Re: Demand for free DTV rising in Australia

Part of the problem is the chipsets for ATSC are so inbred that there is no competition for innovation in software features. There is nothing that would prevent a chipset from making a preliminary scan of the spectrum, note which channels had a signal, even if it couldn't decode the bitstream, and memorize those channels as a question mark or some such. Then the viewer would know that something was on those frequencies, and could manually adjust the antenna for best performance, allowing the chipset to then either decode the VCT and add it to the active channel list, or let the viewer erase that channel from the memory.

I've had and seen various analog TV's that would have to do a new channel scan every time the power went out. But with an analog TV the antenna likely pulls in a snowy ghosty signal even when pointed in the wrong direction for the channel.
If you do the same thing with a digital tuner the channel likely won't even be found by many tuners. That may prove annoying.
