摘要： An interactive information distribution system includes service provider equipment for generating an information stream that is coupled to an information channel and transmitted to subscriber equipment. The service provider also generates a command signal that is coupled to a command channel and transmitted to the subscriber equipment. The service provider also receives information manipulation requests from the subscriber via a back channel. A communication network supporting the information channel, command channel and back channel is coupled between the service provider equipment and the subscriber equipment. The service provider equipment contains two geographically distributed components: central server equipment and a remote video session manager. The central server equipment provides information streams to the remote video session manager in response to information manipulation commands. The remote video session manager monitors and controls distribution of the information stream's substreams to a plurality of subscriber terminals.
