    摘要： A broadcast receiver and a channel information processing method are disclosed. A network interface transmits and receives an Internet Protocol (IP) packet. A controller detects broadcast data included in the IP packet received by the network interface and parses the detected broadcast data to obtain virtual channel information and physical channel information. The channel information is transmitted based on service discovery & selection (SD&S). The virtual channel information is transmitted in a broadcast discovery record and the physical channel information is transmitted in a cable network information record.

    摘要： A host device interfacing with a point of deployment (POD) and a method of processing broadcast data are disclosed. Herein, an Internet Protocol (IP) physical interface unit receives an Ethernet frame including broadcast data; and a routing engine transforms the Ethernet frame to an IP packet when a destination address included in the Ethernet frame matches with an address of a pod and routs the transformed IP packet to an extended channel connected to the POD. Accordingly, it is possible to protect contents using a conditional access provided by the existing cable card and process broadcast data received on all types of transmission protocols including an IP protocol over a wired/wireless network using a channel provided for connection between the existing cable card and the host device.

    摘要： A host device, a point of deployment (POD), and a method for recognizing an operation mode are disclosed. The host device interfaces with a point of deployment (POD), and includes an interface unit and a controller. The interface unit includes CD1#, CD2#, VS1#, VS2#, VPP1, VPP2, and IPDET ports. The controller outputs a mode confirmation signal to the POD via the IPDET port, and identifies that the POD supports an Internet Protocol (IP) Card M-Mode when the mode confirmation signal has been applied to the VS1# and VS2# ports.

    摘要： A broadcast receiver and a system information processing method are disclosed. The broadcast receiver includes a receiver for receiving entitlement management message (EMM) transfer information including information for reception of an EMM over a cable, a network interface for transmitting and receiving data over Internet, and a controller for parsing the received EMM transfer information to determine whether the EMM is applied, and, when the EMM is applied, identifying a transfer method included in the EMM transfer information and controlling the EMM reception through at least one of the receiver and network interface based on the identified transfer method.

    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.

    摘要： A host device interfacing with a point of deployment (POD) and a method of processing broadcast data are disclosed. Herein, an Internet Protocol (IP) physical interface unit receives an Ethernet frame including broadcast data; and a routing engine transforms the Ethernet frame to an IP packet when a destination address included in the Ethernet frame matches with an address of a pod and routs the transformed IP packet to an extended channel connected to the POD. Accordingly, it is possible to protect contents using a conditional access provided by the existing cable card and process broadcast data received on all types of transmission protocols including an IP protocol over a wired/wireless network using a channel provided for connection between the existing cable card and the host device.
