Abstract: The authors propose a technique for formally specifying and modeling the temporal composition of multimedia data. The proposed model is based on timed Petri nets and the logic of temporal intervals. A strategy based on the inter media timing relationships established by the proposed modeling tool is presented for constructing a database schema to facilitate data storage and retrieval of data elements. An algorithm which allows the retrieval of media elements from the database in a manner which preserves the temporal requirements of the initial specification is proposed.
Keywords: multimedia object model (for) synchronization (and) database; timed net; temporal composition; logic (of) temporal interval; data storage (and) retrieval.
