AI summary

A video stream synchronization method, apparatus, and platform, and a computer-readable storage medium. The video stream synchronization method comprises the following: an input node transmits at least two video blocks generated by segmenting a video frame and a message packet to output nodes corresponding to at least two video blocks, respectively, and sends the message packet to a frame synchronization control module in response to a completed transmission of the at least two video blocks and the message packet; the frame synchronization control module processes an initial frame synchronization signal according to a first video identification and a first frame number identification in the message packet to generate a target frame synchronization signal, and sends the target frame synchronization signal to the output nodes corresponding to the at least two video blocks respectively; each of the output nodes parses the target frame synchronization signal to determine a second video identification and a second frame number identification, and sends a video block corresponding to the first frame number identification to a display device when the first video identification is the same as the second video identification, and the first frame number identification is the same as the second frame number identification.
