摘要： A system for generating and sending a Logical Node identification signal as part of a data stream is disclosed. The system also includes subscriber stations capable of receiving and extracting Logical Node identification information from a data stream. The subscriber stations create new messages including the Logical Node identification signal and send the message to the transmission network system control such that switching of data streams to appropriate channel over the information transmission network is done consistent with the network topology.

摘要： A method and apparatus for streaming content to an access network in an interactive information distribution system (100). The method initially encapsulates the content in accordance to an Internet Protocol (IP). In one embodiment, the content is configured as a plurality of a MPEG-2 packets contained in a payload of a Realtime Transport Protocol (RTP) packet (352 - 356) that is contained in an IP packet (300). The content is then transcoded into a format supported by the access network, and streamed over a distribution network to a remote server (201) or to a subscriber terminal that is coupled to the access network (104). The apparatus is embodied as at least one stream caching server (102) for streaming said content as an Internet Protocol (IP) packet to at least one access network via a stream distribution network in response to a request for content, where the content is encapsulated within the IP packet. A packet processor (144) is coupled to the at least one stream server for processing the encapsulated content within the IP packets into at least one packet in a format native to the at least one access network.

摘要： A method and apparatus for preprocessing and postprocessing content in an interactive information distribution system. Content is retrieved from a storage medium (152) and encapsulated in accordance to an Internet Protocol (IP) format. The encapsulated content is then uploaded for storage (146) in a stream caching server (102) and for future streaming of content to different types of access networks.
