发明名称 System und Verfahren zur Synchronisierung von Medienstrom-Spiellisten in Echtzeit
摘要 A multimedia server system includes a disk array subsystem including a plurality of multimedia files, e.g., movies, a media file system manager for managing the storage of the plurality of multimedia files within the disk array subsystem, and a playlist which includes a list of titles of specific multimedia files to be played at designated times. The multimedia server system advantageously includes synchronization parameters associated with each of titles specified by the playlist. The synchronization parameters are programmed to specify the manner in which particular files should be truncated in order to compensate for admission delays. An admission delay synchronization unit receives the synchronization parameters and truncates the multimedia files as specified by the synchronization parameters. In one implementation, a first synchronization parameter is used to specify that the current file should be truncated at the time for the play of the next file. A second synchronization parameter specifies that up to a given amount of time should be sacrificed at the beginning of the next file to account for the admission delay of the current file. In this manner, the beginning of the next file is truncated. Still a third synchronization parameter is provided to specify an amount of time up to which the current file will be truncated at it's end to account for it's admission delay. As a result, the truncated file can be played in a shorter amount of time than the scheduled duration, and the "excess time" created is available to absorb any admission delay. <IMAGE>
