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.
