“…The related research issues include data retrieval [15], delivery of media objects over a network [3,4,8,9,12,29,30], and temporal reasoning and media synchronization [1,25,27,33,36,37]. Also, multimedia authoring and presentation schedule creation have been studied by many researchers [2,6,16,17,19,20,21,24,26,34,38]. Similarly, derivation of retrieval schedules for distributed multimedia presentation has also been studied in many works, such as [17,19,28,29,30,31,35].…”
