The invention relates to a delay testing method of IP video communication system, which uses one computer with detector to operate one clock picture, as testing reference; uses one camera with analogue output to shoot said clock picture; uses the output of camera as the input signal of tested system; the video receiver of tested system receives and decodes and plays the clock picture on one detector; uses one visible light camera to shoot the input and output pictures; therefore, based on the clock difference, the end-to-end delay of system can be obtained. The invention is simple, effective and accurate with low cost. |
