Broadcasting receiver and method of interfacing resource information between a host device and a pod, sending host device resource information and obtaining host device resource information

摘要

A broadcasting receiver and method of interfacing resource information between a host device and a POD, sending host device resource information and obtaining host device resource information are disclosed. A POD sends a resource information requesting message. And a host device receives the resource information requesting message and responds with a resource information message including a resource identifier defined in a resource information table which includes information indicating whether the host device supports A-mode. Using a “conditional access” feature provided by a conventional cable security card, content received through any type of transport protocol (including an IP protocol) including a wired/wireless network can be protected and A-mode resource information can be systematically defined together with other-mode IP communication resource and the resource information of different modes can be integrated and transmitted to the host device.

主权项

1. A host device interfacing with a Point of Deployment (POD), the host device comprising:
a controller configured to: receive an open session request from the POD, transmit an open session response to the POD, transmit a first profile_inq( ) application protocol data unit (APDU) to the POD after the session is opened, receive a first profile_reply( ) APDU containing a list of resource identifiers from the POD, transmit a profile_changed( ) APDU to the POD, receive a second profile_inq( ) APDU from the POD, and transmit a second profile_reply( ) APDU containing a list of supported resources to the POD; 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 broadband interface unit configured to receive a cable broadcast signal carrying second MPEG TS packets through a cable; a multiplexer configured to generate Cab1eCARD MPEG Packet (CMP) by appending a packet header to the first MPEG TS packets from the IP packet and the second MPEG TS packets from the cable broadcast signal as a single packet, multiplex the generated 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.
