ABSTRACT:
A host device interfacing with a point of deployment (POD) and a method of processing a broadcasting data are disclosed. An IP physical interface unit receives a frame including an internet protocol (IP) packet carrying broadcast data through a network modem. 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 an IP MPEG packet by appending a Packet Header carrying identification information to the IP packet, multiplexes the IP MPEG packet and forwards the multiplexed IP packet to the POD.
