Method, cable modem and a device for providing video to a customer premises equipment

A method for providing video to a customer premises equipment, the method comprising:

• receiving radio frequency signals at a radio frequency interface of a cable modem located at a customer premise, wherein the cable modem receives communications from a cable modem termination system (CMTS) and a quadrature amplitude modulation (QAM) device;
• receiving by a data tuner out of multiple tuners of the cable modem, radio frequency signals that convey data;
• detecting, by a monitor of the cable modem, a request to receive a certain video channel that is being broadcast, wherein the request is sent to the cable modem from an internet protocol set top box, wherein the request comprises an Internet group management protocol (IGMP) join request, the IGMP join request comprising a video equipment channel identifier associated with the certain video channel, and wherein the request is for delivery of the certain video channel from the CMTS;
• based upon mapping data that is received at the cable modem from the CMTS and that comprises a mapping between radio frequencies and video equipment channel identifiers and an identification of the video equipment channel identifier associated with the certain video channel within the mapping data, determining that the certain video channel is being provided to the cable modem;
• based on the determination that the certain video channel is being provided to the cable modem, tuning a certain tuner out of multiple tuners of the cable modem, in response to the mapping between radio frequencies and video equipment channel identifiers, to receive the certain video channel in a data over cable service interface specification (DOCSIS) format, wherein the certain tuner is tuned to a radio frequency associated with the video equipment channel identifier associated with the certain video channel according to the mapping data, wherein the certain video channel is retrieved by the cable modem from the QAM device, the QAM device receiving content associated with the certain video channel from a switched digital video source, and wherein the certain video channel is delivered to the cable modem as certain video channel information that is encapsulated with data layer encapsulation information;
• preventing the request for the certain video channel from being transmitted to the CMTS;
• removing data layer encapsulation information that encapsulates the certain video channel information at the cable modem to produce an internet protocol video signal at the cable modem;
• and
• transmitting the certain video channel information from the cable modem, the certain video channel information comprising the internet protocol video signal produced by the removal of the data layer encapsulation information, and the certain video channel information being transmitted to the internet protocol set top box.
