Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted through the network in traditional compression systems, then remote monitoring and display functions are achieved, but network bandwidth is excessively occupied, impacting other functions and system performance
Solution Approach 1:
The patent extracts and transmits only the differential data between adjacent video frames rather than complete frames. By identifying and transmitting only the changed portions (using difference calculation and run-length encoding), the system significantly reduces the quantity of data occupying network bandwidth while maintaining remote monitoring functionality.
Solution Approach 2:
The patent applies different processing methods to different regions of video data. Static regions are represented by reference to previous frames, while only dynamic regions are fully encoded and transmitted. This local differentiation reduces overall data volume without compromising the quality of moving objects in the video stream.
2Loss of information
If complete video frames are transmitted, then video quality is maintained, but network bandwidth consumption increases excessively
Solution Approach 1:
The patent performs preliminary difference calculation and run-length encoding on video frames before transmission. By pre-processing the data to identify and compress only the essential differential information, the system reduces transmission volume while ensuring that all necessary visual information is preserved for accurate video reconstruction at the receiving end.
Solution Approach 2:
The patent creates a simplified copy of video data by transmitting only the differential portions between frames rather than complete frame copies. This selective copying approach maintains video information integrity for changed regions while eliminating redundant data transmission, significantly reducing bandwidth consumption.
3Quantity of substance
If video compression is applied, then network bandwidth usage is reduced, but processing time and complexity increase
Solution Approach 1:
The patent segments the video processing task into distinct stages: difference calculation between adjacent frames, run-length encoding of differential data, and selective transmission. This segmentation allows each processing stage to be optimized independently and enables parallel processing of multiple frames, reducing overall processing time while achieving significant bandwidth reduction.
Solution Approach 2:
The patent applies partial compression by focusing computational resources only on identifying and encoding the differential portions between frames rather than compressing entire frames. This partial action approach reduces processing complexity and time while still achieving substantial bandwidth savings by eliminating redundant frame data.

AI summary
The present application discloses method for transmitting video data, applied to chip for substrate management control. The method includes: respectively storing video compression data into first storage space and second storage space according to ping-pong operation structure; reading data of the same byte length from the first storage space and the second storage space; determining whether similarity between first data to be transmitted and second data to be transmitted is greater than or equal to preset value; if yes, setting the first data to be transmitted added with first transmission identifier as the current frame of data, and setting a second transmission identifier corresponding to the first transmission identifier as the next frame of data; and sending the current frame data and the next frame data to video data receiving end.
