Abstract
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.
