Synchronization validation mechanism in multimedia document presentation - Systems, Man, and Cybernetics, 2000 IEEE International Conference on

Synchronization is the major processing task during multimedia presentation, which defines the time relation between multimedia objects. There are many synchronization specification methods, and each has different advantages and disadvantages. Those methods work well for simple and specific synchronization case, but when consider to large complex multimedia presentation, there lack effective method to deal with complex time relation. In this paper, a synchronization point based specification method (SPM) is proposed, and based on it, static and dynamic validation mechanism for synchronization relation is given. In SPM, synchronization relation is defined in synchronization points (SP). Multimedia presentation control is based on SP’s status during presentation. According to the order of SPs, SPM gives the static and dynamic validation algorithm, which can avoid conflict relation between SPs. SPM give a way to define non determined synchronization relation between multimedia objects, and proposes static and dynamic validation mechanisms for complex synchronization control. This synchronization point based mechanism can extend the capability of synchronization definition and controlling in multimedia system.
