Digital Satellite Broadcast Program Distribution Over Multicast IP Broadband Networks

摘要

Systems and methods for distributing digital satellite broadcast programs over multicast Internet Protocol (IP) networks are provided. A satellite receiver gateway receives a signal from a digital satellite broadcast and generates service information multicast packets that are transmitted over a multicast IP network. A device receives the service information multicast packets and generates a channel list or electronic program guide for a user. When a user selects a service from the channel list or electronic program guide the device sends a service request for the service towards the satellite receiver gateway. Either the satellite receiver gateway or a switch within the multicast IP network can then transmit the service in multicast IP packets to the requesting device.
