Claim:
A method to identify video decoding errors in an output stream of motion video produced by a video device, the method comprising: receiving the output stream of motion video from the video device, wherein the output stream comprises a plurality of output frames each produced by the video device in response to a predetermined input, and wherein each frame of the plurality of output frames comprises a frame identifier and at least one object presented on a consistent background, wherein an expected location of the at least one object varies from frame to frame; for each of the plurality of output frames, associating the output frame with a frame template based upon the frame identifier, wherein the frame template defines an expected location of the at least one object within the output frame, and verifying that all of the pixels of the output frame located outside of the expected location of the at least one object conform to the consistent background so that all of the pixels of the at least one object lie within the expected location defined by the frame template.
