摘要：A data distribution system and a protocol for interactive information servicesover a network and in particular for video-on-demand applications. A shared buffer and asplit-and-merge protocol are implemented to allow multiple users to share the samevideo stream multicasted over a network with true VOD services including the ability to
access any available video at any time, and to perform any VCR-like functions and randomaccess. Video requests for a video program are served in batches. A user interaction isfirst handled by splitting off the interactive user from a shared video stream in a batch,and by subsequently assigning the user a new dedicated video stream. The interactiveuser is subsequently merged back to one of the batching video streams shared bymultiple users upon resuming normal play mode.
