Claim:
A host device interfacing with a Point of Deployment (POD), the host device comprising: an Internet Protocol (IP) physical interface unit configured to receive an IP packet carrying first Moving Picture Experts Group (MPEG) Transport Stream (TS) packets through an IP network; a decapsulator configured to extract and route the first MPEG TS packets to a multiplexer; a broadband interface unit configured to receive a cable broadcast signal carrying second MPEG TS packets through a cable; a demodulator configured to demodulate the cable broadcast signal based on a Quadrature Amplitude Modulation (QAM) method; the multiplexer configured to generate CableCARD MPEG Packets (CMPs) by appending a packet header to the first and second MPEG TS packets, multiplex the CMPs and output the multiplexed CMPs to the POD; a descrambler configured to decrypt CMPs encrypted by the POD and process the decrypted CMPs to be suitable for a demultiplexer; and the demultiplexer configured to separate the processed CMPs and route the separated CMPs.
