Integration Application of 8K Ultra HD Video and DMS Audio Broadcast System

Abstract

In recent years, people’s demand for audio and video playback quality has gradually increased. High definition video and high reduction audio are two important index. The 8K ultra-high-definition television broadcasting system was developed by Beijing HeXinChenGuang Information Technology Co., Ltd. It can broadcast ultra-high-definition uncompressed video signals with a bandwidth of 8GB/s and a resolution of 7680×4320. The Dynamic Matrix Sound (DMS) is a new multi-channel pickup system based on the principle of sound field optimization and the Huygens principle. DMS is developed by the Key Laboratory of Media Audio Education of the Communication University of China. This paper proposes a communication method that integrates the above two systems. It mainly describes an application layer protocol based on User Datagram Protocol (UDP). It focuses on the message distribution and message transmission mechanism of the protocol. The operating conditions can achieve synchronous playback of 8K ultra-high-definition video and DMS audio. The integration application of 8K ultra HD video and DMS audio broadcast system is realized.
