Measurement display device and measurement system for end-to-end video transmission delay

The invention discloses a measurement display device and a measurement system for an end-to-end video transmission delay. The device comprises a high-speed time stamp generator and at least two display controllers, wherein each display controller is connected with a display unit; the display units are in arrayed distribution to form a display array; the high-speed time stamp generator is used for acquiring synchronous time from a GPS (Global Positioning System) time service clock at a predetermined time interval to generate a time stamp and sending the time stamps generated in different periods of time to the display controllers in sequence; the display controllers are used for acquiring the time stamps which are sent from the high-speed time stamp generator so as to drive the display array; the display array is used for displaying the time stamps generated in different periods of time on each display unit in sequence respectively. According to the device and the system, the measurement accuracy of a time delay is improved, and the requirements on the time delay measurement accuracy of a video processing system which is highly sensitive to the time delay are met; meanwhile, measurement system equipment is simple, and the cost is greatly reduced.
