And it's interesting that those rates are comparable to what's
being done in NTSC while also transmitting analog television.
You're talking about Dotcast, I take it.
The bit rate is 4.5 Mb/s in the 6 MHz channel, while also transmitting
NTSC, yes.
BUT
For Dotacast to work, they claim a need for a 40 dB of C/N. I can tell
you that I don't see that sort of C/N for any DTT channels I receive.
Sure, given enough power, you can increase the payload on any channel.
