AI Technical Summary

Technical Problem

In large-scale lighting systems, how to ensure accurate synchronization of video program playback of multiple nodes, especially when facing problems such as network delay, equipment clock out of synchronization and node communication disconnection, the existing technology cannot effectively solve it, resulting in a decrease in the overall display effect of the light show and affecting the audience's experience.

Method used

By performing structured encoding and node state clustering analysis on the status information of each node in the node cluster, the node with the best performance is elected as the master node, and the video basic information is obtained through the master node, and the playback frame information is calculated, and the target frame of the slave node is adjusted using network delay to achieve frame-level synchronization.

Benefits of technology

Even in the case of local network jitter or short-term communication interruption, it can ensure that the nodes operate based on unified logic, improve the visual consistency and expressiveness in scenes such as light shows, and achieve accurate picture synchronization between large-scale node clusters.

Abstract

The invention provides a node synchronous playing method and system for a distributed player, and relates to the field of video playing, and the method comprises the steps: carrying out the structural coding and node state clustering analysis of the state information of each node in a node cluster, obtaining the maximum one in a set of node performance deviation values through the calculation of the node performance deviation values, and obtaining the maximum one in the set of node performance deviation values; the corresponding node is used as a master node, and the rest are slave nodes. Then, acquiring basic information of the video through the main node, calculating playing frame information and sending a playing state; then, the target frame of the slave node is adjusted through the network delay between the slave node and the master node, and frame-level synchronization is maintained; thus, even in the face of local network jitter or transient communication interruption, it can be guaranteed that the nodes operate based on unified logic, visual coherence and expressive force in scenes such as light show and the like are improved, and accurate picture synchronization between large-scale node clusters is achieved.
