ABSTRACT:
A system and method for delivering cost-reduced, low latency, wider variety video-on-demand for digitized motion pictures. Leader files stored in disk array are accessible quickly for viewing in response to the user's selection, thereby providing low latency time from the initial request to the viewing of the leader. The remainder of the digitized movie files are stored in a robotic tape library archive system having greater access time than disk array storage but at significantly reduced storage cost. During the viewing of the leader from the rapidly accessible disk array, the remainder of a selection is accessed at a slower rate on tape and transferred to disk for viewing seamlessly at conclusion of the leader. The hybrid rapidly accessible disk storage of leader and cost effective bulk storage on tape of the remainder of selections provides both low latency and significant storage cost reduction, thereby increasing the number of video selections which may be offered.
