Using graphics processing unit ("GPU")-generated data in-situ to characterize the ability of a cable to carry digitized video

Disclosed are an apparatus, a computer device, a system, computer readable media and a method for using graphics processing unit ("GPU")-generated data to characterize, in-situ, the ability of a cable to reliably carry digitized video, among other things. In one embodiment, a computing device includes a processor coupled via a system bus to a graphics engine and a video cable-testing apparatus. This apparatus has an input port configured to couple to the digitized video cable to receive pixel data generated by the graphics engine. It also has a signal integrity evaluator ("SIE") configured to identify the digitized video cable as the source an amount of data corruption, the amount of data corruption being a function of the pixel data. The signal integrity evaluator includes a classifier to classify the amount of data corruption into classes that each represents various degrees of degradation of the computer-generated video images.
