Design and Implementation of 4K-UHD Multichannel Video Synchronization Based on MMT Protocol

Abstract

In this paper, we propose a practical synchronization mechanism to achieve synchronized playback of the arrived 4K video bitstreams at different terminal devices based on MMT (MPEG Media Transport) protocol. In addition to the synchronized playback, we achieve the video playback with minimum service latency by estimating the accurate total end-to-end delay between the server and receiver. The conventional synchronization method between multiple clients generally calculates the time difference through communication between each client. Communication between multiple clients increases complexity and consumes network bandwidth. We do not rely on the communication between multiple clients but exploits the timestamp information supported by the MMT protocol.
