Abstract:
A method and apparatus that tests video quality includes a superimposing of at least one code to a video that is to be transmitted by a communication device to another communication device. The at least one code is transmitted such that the superimposed at least one code is extractable and readable from the decoded video by the device that receives the transmitted video. The extracted at least one code may then be read to determine the quality level of the transmitted video. The determination of quality for the received video may be based upon one or more tests performed using at least one code extracted from the received video.
