A synchronized playback method with dynamic buffering time awareness for media streaming

We propose a synchronized playback method for the real-time synchronization of the playback position of streaming media to multiple clients from a streaming server. The playback-related information that is used in this synchronized playback method comprises the current time and the playback position, and the server transmits the playback position and the current time to the client. The client can determine the playback position of the server based on the playback position and the current time and can synchronize playback using this information. In this paper, we describe the configuration of the experimental environment for synchronized media playback and present the synchronization algorithms used in this method for both the server and the client. Then, we present a method for measuring the synchronization accuracy and the results of such measurements. The average synchronization accuracy is 26 msec. According to the Haas effect, the experimentally measured sync accuracy is sufficiently high that the corresponding sound error is not detectable by the human ear.
