A Multimedia Synchronization Protocol For High Speed Networks

Abstract

In this paper, we propose an MASP(Multimedia Association Synchronization Rotocol) to transmit multimedia data with a temporal relationship on general networks not guranteeing a constant delay time. As existing synchronization schemes have been proposed for future network not to be implemented or for specific environments to their applications, they are difficult to be implemented in general network such as packet networks or Internet which is composed of heterogeneous networks. Our protocol adopts a model which has group connections called associations between two hosts. The transmitter part schedules transmission times considering the delay time of each transmission path for packet to arrive on time. The receiver part playouts the packet with intermedia synchronization function, if necessary. T h e protocol frequently measures delay on the transmission path for exact scheduling, and provides a playout capability in environments where no global clock is maintained.
