Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video frames are segmented into blocks and processed by different output nodes, then the processing capacity and adaptability are improved, but image synchronization and display coherence deteriorate
Solution Approach 1:
The patent segments video frames into multiple video blocks and processes them through different output nodes simultaneously, dividing the processing task to improve system capacity and adaptability while maintaining overall image coherence through synchronized control
Solution Approach 2:
The frame synchronization control module receives feedback from multiple output nodes about their processing status and dynamically adjusts synchronization signals to ensure that segmented video blocks are reassembled in the correct temporal sequence, resolving the synchronization issue caused by parallel processing
2Productivity
If different processing methods are used for local and network video streams, then the processing efficiency is improved, but maintaining image synchronization becomes more difficult
Solution Approach 1:
The frame synchronization control module serves as a universal control mechanism that manages both local and network video streams regardless of their different processing methods, coordinating multiple output nodes through a unified synchronization protocol to maintain image coherence across diverse processing paths

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.
