<p>A multi media presentation is divided into sequential segments, each segment having a time lenght, the transmission of the segments of teh multimedia presetnation is then scheduled according to a specified delay time that does not depend on the time lenghts of the segments, and the segments are then transmitted over a broadcast network according to the schedule for each segment so computed. perferably, a trnasmission bandwidth of multiple times that of the multimedia presentation is allocated for transmission of the segments and each segment is then transmitted repeatedly based on the computed schedule. In cases of conflict, later segements are schedueld earlier and thsu transmitted more frequently than desired. Once transmitted, the segments may be received and stored in temporary storage, and then played back as soon as the delay time has elapsed.</p> |
