It is not quite clear to me what you have in mind - do you want to send exclusively IP television over the cable system, or do you want to fit IP into an existing system ?
Current cable systems have separate parts of the spectrum reserved for analogue or digital television channels and the inbound and outbound IP. DOCSIS is a standard for sending data over a HFC system - see http://www.cablemodem.com/ There is lots of hardware for this from different vendors. If you want a new technology system, I would recommend multicast IP MPEG-2 over EPON - maybe in conjunction with MPLS - see http://www.iec.org/online/tutorials/epon/topic04.html If you are interested in setting up these multicasts or for content to put inside of this walled garden, please let me know :) I do not think that this is really germane to NANOG.
