PURPOSE: A QoS(Quality of Service) management method for multimedia synchronization is provided to secure the minimum QoS by changing weight values with respect to multimedia objects. CONSTITUTION: Weight values are provided to multimedia objects. State maintenance parameters(21a-23c) about the multimedia objects are defined, and default values are provided to the state maintenance parameters(21a-23c). It is judged whether a process of a certain object is stopped by backtracking. If the process of the certain object is stopped by the backtracking, a state maintenance parameter value about the object is decreased. It is judged whether the state maintenance parameter value of the object is 0. If the state maintenance parameter value of the object is 0, an ignition value of a corresponding transition function of the object is increased twice. The state maintenance parameter and the weight value of the object are compulsorily increased. The object waits for a next transition until the object is perfectly transmitted.
