While we're at it: The TDA10023 also supports MCNS in addition to DVB-C.
After a quick gaze at [1] I understand that MCNS is somehow connected or
equal to DOCSIS, which uses shorter TS packets (122 bytes).
DOCSIS uses the normal MPEG-2 TS. If you want to, you can mix DVB-C and
DOCSIS into the same TS. In practice this never happens, as it is a
costly usage of CMTS resources, and no CMTS supports it.
If you want a peek at the DOCSIS standards, hop over to
http://www.cablemodem.com/ where you will find all relevant specs. For
this you want the RF spec.
Cheers,
Rudy
