Hi.
I'm currently using a Nova-T card for terrestrial DVB, but would like to add a DVB-C card and connect to cable.
Am I right in assuming that channels on cable are organised much like on terrestrial, with 3 or 4 transponder frequencies carrying 3 or 4 channels each? I wonder, because as the cable is provided by a single supplier, I wasn't sure how the channels are mapped.
Secondly, are channels that require CAM decrypting all generally on the same transponder? Or are these pay-channels interspersed with the free- to-air ones across the frequencies?
Thanks

there are frequencies, that can carry an amount of services. depending on bandwith that can be carried. there is nothing, that depends on how much provider do insert data.

why is that important? normally FTA and Crypted can be seperated or mixed on transponders. also a matter of bandwith, how much of those can be carried
Thanks

Yeh, that works like a charm.

In the UK at least, you'll find about 20 'transponders', each of which carries about 10 TV channels in QAM64.

Yes, there's at least a 'BBC' and an 'ITV/C4/5' which are all FTA. Pretty much everything else is crypted except the TV shopping channels and the radio stations.
Cheers, Gavin.
