Abstract (en)

[origin: WO9602876A1] A system for preprocessing and delivering multimedia presentations to customers (601) such that delays due to interactive response time is virtually eliminated include a preprocessor (200), mass storage (300), a delivery processor (400), a distribution network (500), and a plurality of presentation processors (600). The preprocessor (200) receives as inputs an original multimedia presentation and parameters characterizing other system components, which parameters include the round trip latency between the delivery processor (400) and presentation processor (600), and generates a preprocessed multimedia presentation including a delivery schedule in the form of a labelled, directed graph. In generating the delivery schedule, the preprocessor (200) ensures that each object of the presentation and its associated presentation command arrive at the presentation processor (600) no later than its presentation time.
