digital TV signals. The digital cable and the digital broadcast channels
use slightly different standards.
See http://en.wikipedia.org/wiki/Digital_Video_Broadcasting
Of note, there are broadly DVB-S (for satellite), DVB-C (for cable) and
DVB-H (for "terrestrial").
I have a dual-analog/digital unit (I forget the model), however if you
read the documentation on it, it only supports DVB-H. In Bloomington,
this means it is only useful if I want to pick up PBS or Christian
stations. (We only use the analog side of it.)
To be able to pick up digital cable signals, you need something capable
of handling DVB-C signals. Specifically, you need something with
CableCARD support. You'll also need to sign up for a CableCARD from your
cable company.

I didn't know that you could get any remotely usable signals without a
CableCARD, so I'm impressed.
Cheers,
