Patent

CA 2281440

A method and system for playback of live and pre-recorded multimedia data in real-time over a large scale communication network, such as the world-wide web. The invention allows a user connected to a specialized network to play back a multimedia broadcast. The invention includes a process that allows multimedia content to be created and scheduled as a playlist. The playlist data is compressed and transmitted to a host system as part of a capture protocol. The captured playlist data may then be "broadcast" to users. A user may choose a channel selection from a playlist, and cause the selected item to be downloaded and played back by means of a playback tool. The host system includes a highly efficient distribution system that allows a large number of users accessing the host through Terminal Information Handlers to rapidly access one or more channels of multimedia data. The system architecture provides a "fan out" mechanism that includes a master broadcast process that accepts a multi-stream data flow and then distributes the mufti-stream data flow to essentially every Terminal Information Handler accessible to the host. The load of providing data streams is thus spread among a large number of Terminal Information Handlers, reducing access latency and providing support for hundreds of thousands of users over a large scale communication network.
