摘要：A realtime video quality measurement instrument may be configured for bothdouble-ended and single-ended operation. For double-ended operation reference andtest video signals are stored in respective buffers and spatial/temporally aligned. Desired
quality measurements are performed on the aligned frames of the test and referencevideo signals according to stored setup instructions. For single-ended operation thereference video signal and a signature for the reference video signal are pre-storedtogether with the desired quality measurements for the frames of the reference videosignal. Then the test video signal is received, signatures determined, and the test andreference video signals aligned using the signatures. The desired quality measurementsare then performed on the aligned frames of the test and reference video signals.
