Are you ignoring compression?

I'd have to dig a bit to give you a complete answer but I do know that our analog cable company squeezes more than 100 analog channels down their coax and uses heavy compression to do it. DTV signals are already compressed and while they can be compressed a little (which the companies do) its nowhere like analog.

Our TV allows > 100 channels on analog CATV.

I suspect that the bandwidth is less than 600MHz throught the network and there are unusable parts (joins and distribution boxes trim the available spectrum).

I see you're right about cable HD - they use 16-VSB rather than the 8-VSB used for OTA and thus can get 2xHD in one band on digital cable. I hadn't realized this.

Well the choice of fiber seems redundant for this purpose doesn't it.

Thanks - I learned something!
