Method for automatically testing video display/monitors using embedded data structure information

摘要

Method and system for testing any type of video display, video monitor or other device that produces a video signal, and that is capable of providing information about the video and optionally audio specifications and/or capabilities of the output signal to an external device when coupled thereto. The external device obtains the information about the specifications and/or capabilities and based thereon, assembles one or more pre-defined tests from a test database/repository containing tests to enable testing of compliance of the video signal producing device to those specifications and/or capabilities. This compliance testing may entail generating video or audio content at a source generator, providing it to the video signal producing device, and determining the accuracy of the output of the video signal producing device to the input content. A determination of the results of this test may be provided to an operator of the testing apparatus.

主权项

1. A method for preparing for testing a video signal producing device, comprising:
interrogating the video signal producing device to cause an Extended Display Identification Data (EDID) data structure of the video signal producing device to be directed from the video signal producing device to a processor in response to the interrogation; selecting, at the processor based on the EDID data structure received from the video signal producing device, at least one test to perform on the video signal producing device, from among a plurality of different tests, each of the plurality of tests being associated with a specific content of EDID data structure such that when the received EDID data structure is parsed, one or more of the different tests is selected based on the parsed EDID data structure; retrieving the selected at least one test from a test database/repository that stores the plurality of different tests; directing the selected at least one test to a source generator coupled to the video signal producing device; and then generating and outputting from the source generator based on the selected at least one test, a signal to the video signal producing device to enable output of the video signal producing device in response to the signal received from the source generator to be used to assess compliance with at least one specification or capability of the video signal producing device, whereby when the selected at least one test is performed on the video signal producing device, compliance of the video signal producing device with the at least one specification or capability of the video signal producing device is assessed and different EDID data structure received from the video signal producing device results in different selection of the at least one test.
