| titleOfInvention | A high-precision video transmission delay test system |
| abstract | The utility model discloses a high-precision video transmission delay testing system, which comprises two high-precision timers, which are timer A and timer B respectively, a camera, an image transmission transmitter, an image transmission receiver, a display and a Camera; wherein, the camera is aligned with the timer A and connected with the image transmission transmitter, the image transmission receiver is connected with the display, and the display is used to display the image of the timer A captured by the camera transmitted by the image transmission transmitter, and the shooting area of the camera Override timer B and display at the same time. The utility model is equipped with timers respectively at the image transmission transmitting end and the image transmission receiving end of video transmission, and simultaneously collects the timer and the local timer displayed after transmission through the camera at the image transmission receiving end, and directly calculates the time difference between the two, The accurate measurement of the delay parameters can be completed. The time delay measurement accuracy of the system can reach the order of ms, and the measurement can be performed online when the video transmission system works at a long distance. |
