  • Patent number: 7900237
    Abstract: A digital cable TV receiver includes a POD module and a host device. The host device includes a controller and a HDMI port linked to a first peripheral device. When the controller receives a diagnostic request for HDMI status from the POD module, it generates a HDMI status report and transmits the DVI status report to the POD module. The HDMI status report includes HDMI status information associated with the first peripheral device. If the host device further includes a DVI port linked to a second peripheral device and receives a diagnostic request for HDMI/DVI status from the PDO module, it generates a HDMI/DVI status report and transmits the HDMI/DVI status report to the POD module. The HDMI/DVI status report includes HDMI status information associated with the first peripheral device and DVI status information associated with the second peripheral device.

  • Patent number: 7860109
    Abstract: A host device interfacing with a point of deployment (POD) and a method of processing a broadcasting data are disclosed. A broadband interface unit received a MPEG transport packet through a cable. A demodulator demodulates the received MPEG transport packet. An IP physical interface unit for received a frame including an internet protocol (IP) packet through a network. A routing engine transforms the frame to an IP packet and routs the IP packet based on a destination information included in the frame. And a multiplexer generates IP MPEG packet and CableCARD MPEG packet by appending a Packet Header carrying identification information and packet identification information to each of the IP packet and the demodulated MPEG transport packet, multiplexes the IP MPEG packet and the CableCARD MPEG packet and sends the multiplexed IP MPEG packet and CableCARD MPEG packet to the POD.

  • Patent number: 7839886
    Abstract: 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 checks an operation mode of the POD. The interface unit includes CD1#, CD2#, VS1#, VS2#, VPP1, VPP2, and ISIO16# ports. The controller detects Card Information Structure (CIS) information from the POD if each of the VS1# and VS2# ports is set to ‘Logic Low’, and determines whether the POD supports an Internet Protocol (IP) Card S-Mode on the basis of the detected CIS information.

  • Publication number: 20100260182
    Abstract: 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.
