Abstract

HD video and high reproduction audio are two important playback indicators. The 8K ultra-high-definition video player developed by our team has reached a practical level. The multi-channel sound system (DMS) is a new multi-channel sound-recovery system based on the sound field optimization principle and Huygens principle developed by CUC. Through experiments and theoretical analysis, this paper studies the operation mechanism of ultra-high definition shared living room audio and video playback system, summarizes the common techniques of audio and video synchronization at home and abroad, and provides a feasible synchronous implementation method, which makes the audio and video synchronization error range. To meet the requirement of relevant national standards, the ultra-high-definition video and audio broadcast system shared living room is realized.

Keywords
