Abstract:
1. A broadcast receiver comprising: a Point of Deployment (POD) that transmits a first application protocol data unit (APDU) requesting an internet protocol (IP) address of the POD to a host device; and the host device that transmits a second APDU including the IP address of the POD to the POD in response to the first APDU, wherein the host device comprising: an IP physical interface unit that receives an Ethernet frame including an IP packet which carries first moving picture experts group (MPEG) transport stream (TS) packets through an IP network; a broadband interface unit that receives a cable broadcast signal which carries second MPEG TS packets through a cable network; a decapsulator that extracts the first MPEG TS packets from the IP packet; a multiplexer that generates CableCARD MPEG Packets (CMPs) by appending a packet header to the first and second MPEG TS packets, multiplex the generated CMPs and output the multiplexed CMPs to the POD; a descrambler that decrypts CMPs encrypted by the POD and process the decrypted CMPs for a demultiplexer; and the demultiplexer that separates the processed CMPs and route the separated CMPs.
