Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image recognition with correlation analysis is used to measure video quality, then measurement accuracy is improved, but computational complexity and hardware costs increase
Solution Approach 1:
The patent uses barcodes as simplified copies or representations of video frame quality indicators. Instead of analyzing entire video frames through complex image recognition, the system embeds barcodes that encode essential quality information, allowing accurate measurement through simple barcode reading operations rather than full image correlation analysis
Solution Approach 2:
The patent extracts only the necessary quality measurement information from video frames by embedding barcodes that contain encoded quality data. This extraction approach removes the need for complex full-frame analysis, isolating the essential measurement function from the redundant visual content while maintaining measurement accuracy

AI summary
A measuring system for measuring video processing quality of a device under test includes a measuring device comprising transmission means set up for transmitting a video to the device under test. The device under test is set up for receiving the video and displaying it using a display included by the device under test. The video includes at least a first barcode to be displayed for a first duration. The measuring system includes a barcode reader set up for reading the first barcode from the display of the device under test. The measuring system is set up for determining the video processing quality of the device under test based upon measuring results of the barcode reader.
