ABSTRACT:
A multi-media scheduling system for scheduling multi-media applications which include media having priorities based on time restrictions. The multi-media scheduling system includes a managing unit for managing requests of each of the media of the multi-media applications, a sorter for rearranging the requests managed by the managing unit in a sequence starting from a request having a strongest time restriction, and a preemptive scheduler for scheduling the rearranged requests in the managing unit by reducing priority of at least one request which has a predetermined priority information lower than a predetermined value if the time restriction of the media prevents desired scheduling, where the predetermined priority information is selected from at least a group of information consisting of a quality which indicates a tolerance of a delay from a request time of each request and an importance which indicates an importance of each request.
