This application discloses a distributed audio and video synchronization method based on multi-field
coupling, relating to the field of distributed audio and video synchronization technology. It obtains the time progress field,
rhythm field, and semantic field through multi-source node state data broadcast by neighboring nodes, and obtains the time progress error,
rhythm error, and semantic error based on these fields. The optimal playback speed is determined based on the time progress error,
rhythm error, and semantic error, and the synchronization mode is determined based on the semantic error. Finally, an audio and video synchronization control strategy is generated based on the optimal playback speed and synchronization mode. This strategy is executed, and the process enters the next synchronization cycle until the convergence condition is met, completing synchronization. Through multi-field
coupling, synchronization from
time alignment to perceptual consistency is achieved, balancing playback continuity, rhythm consistency, and
semantic consistency, thus improving the audio and video synchronization effect and user experience in a distributed environment.
