Samsung patents video test system that checks for display errors

This patent describes a method for testing video equipment by sending a specific test video through a system. The device compares the pixel values at different stages of processing to expected values to find errors in the source, processor, or display.

Why it mattersIt helps manufacturers ensure that video signals are processed correctly before reaching the screen, which is a standard quality control step in hardware production.

In the filing’s own words

A sink device comprises processing circuitry configured to, receive a test video from a source device, perform a standardization operation on the test video to generate a standardized video, scale the standardized video to generate a scaled video, perform an image quality processing operation on the scaled video to generate a sampling video, output the sampling video to a display, the display configured to display the sampling video as a final sampling video, and detect at least one error generated in any one of the source device, the processing circuitry, or the display based on pixel values of the test video, the standardized video, the scaled video, the sampling video, and the final sampling video and desired pixel values corresponding to the type pattern included in each of the plurality of frames.

What exactly they claim (claim 1)

1. A sink device comprising: processing circuitry configured to, receive a test video from a source device, the test video including a plurality of frames and each frame of the plurality of frames including a type pattern of a plurality of type patterns, each type pattern of the plurality of type patterns corresponding to a frame number of a respective frame of the plurality of frames, and each type pattern of the plurality of type patterns being different, perform a standardization operation on the test video to generate a standardized video, scale the standardized video to generate a scaled video, perform an image quality processing operation on the scaled video to generate a sampling video, output the sampling video to a display, the display configured to display the sampling video as a final sampling video, and detect at least one error generated in any one of the source device, the processing circuitry, or the display comparing pixel values in each of the standardized video, the scaled video, the sampling video, and the final sampling video to desired pixel values corresponding to the type pattern included in each of the plurality of frames of the test video.
