  • Seamless multimedia branching
    Patent number: 6343298
    Abstract: Described above are methods of authoring multimedia titles and of storing and delivering multimedia content that implements guaranteed seamless branching on digital media with high seek latency and a fixed upper bound on this latency. Continuous media content is arranged as individual clips on a storage medium. Seamless branches between clips are identified by an author. A method is disclosed to identify individual clips as carrier clips or non-carrier clips to guarantee specified seamless behavior while optimizing bridge memory usage and availability of seamless jumps. Bridge data of a particular target media clip is interleaved or otherwise associated on the storage medium with a carrier clip that is upstream of the target media clip, and delivered along with the upstream media clip. As bridge data are delivered, they are stored in bridge memory, to be used to implement a subsequent seamless branch.
