Stability Analysis of Distributed Multimedia Playout Synchronization Using Buffer Level Control

This paper analyzes the multimedia synchronization model from the viewpoint of cybernetics to get the relation of system parameters. The stability of a typical buffer-oriented playout synchronization system is analyzed based on Routh criterion. The sufficient and necessary conditions of stability are obtained. The restriction relationship between two important system parameters: synchronization adaption phase L and smoothing factor a is also given.
