Compensation Buffer in Multimedia Synchronization Systems

In multimedia systems end to end delay jitter often leads to the discontinuity of information playback. Therefore a mechanism that maintains the jitter and the skew variations bounded within suitable values must be adopted in order to preserve the intra media and inter media temporal relationships. In this paper, a mapping relationship from P -QoS to buffer, which is used to compensate for delay variations, is given based on delay jitter statistics, and its theoretical analysis is also shown. So the designation rule of buffer size of multimedia synchronization system can be determined. The experimental results show that the compensation buffer size determined by this method can completely satisfy P -QoS.
