Patent ID: 7944916

Claim:
A method of processing broadcast data in a host device interfacing with a point of deployment (POD), the method comprising: receiving an Ethernet frame including an internet protocol (IP) packet which carries a first moving picture experts group (MPEG) transport stream (TS) packet through an IP network, and a cable broadcast signal including a second MPEG TS packet through a cable, wherein the first and second MPEG TS packet includes broadcast data coded by at least one of MPEG-2, MPEG-4 and H.264; demodulating the cable broadcast signal; routing the IP packet based on a destination IP address included in the Ethernet frame using a layer-3 routing method; extracting the first MPEG TS packet from the IP packet; generating a CableCARD MPEG Packet (CMP) by appending a packet header carrying identification information to the first and second MPEG TS packet, respectively, wherein the identification information is a local transport stream identifier (LTSID) and is based on an IP address included in the IP packet; and multiplexing the generated CMPs and sending the multiplexed CMPs to the POD.
