OFF-LINE DEVICE TESTING USING VIDEO AND AUDIO CODE CONTROL

摘要

An apparatus for testing a device (DUT) includes a peripheral controller configured to communicate with an application embedded in the DUT. The application is configured to run self-diagnostic tests. An audio interface is arranged to transmit audio codes between the apparatus and the DUT on the basis of the tests, wherein the peripheral controller is coupled to the audio interface, being configured to encode and decode the audio codes. A method of testing a DUT includes running a DUT embedded application configured to run self-diagnostic tests. Running the application comprises transmitting encoded audio command signals via an audio interface from a testing apparatus to a microphone configured with the DUT to initiate self diagnostic tests, receiving audio response signals from the DUT generated on the basis of the tests via an audio interface configured with the testing apparatus, and decoding the received audio response signals by a peripheral controller.
