Multimedia playout synchronization using buffer level control

Abstract

This paper presents a new approach to the intrastream synchronization problem. The proposed technique is based on controlling the receiver buffer. The basic idea is to find realistic models for the control loop components and to apply automatic control methods to choose an appropriate control algorithm and to derive stability criteria and transient behavior of the whole system. The theoretical results are shown to have good accordance to real, measured system behavior. The synchronization method has been implemented and first experiences could be gathered with a video phone application.
