    摘要： A method and device for separating a rebroadcast video and an on-site displaying video, for use in the field of LED display screens. The method comprises: transmitting a rebroadcast video and an on-site displaying video of an LED display screen to a video processor by two paths; overlaying the two paths of videos by means of the video processor and transmitting the overlaid video to an LED display control system; the LED display control system controls the proportions of the two paths of videos and uses a high-speed camera to synchronously capture the rebroadcast video according to the proportions of the videos; the LED display control system receives the rebroadcast video synchronously captured by the high-speed camera; the LED display control system converts the rebroadcast video to a video needing to be rebroadcast to different countries by means of image processing. On one hand, the separation of a rebroadcast video and an on-site displaying video on LED display screens around a gymnasium is implemented, thereby meeting different requirements of different countries; on the other hand, the present invention is compatible with the traditional LED video displaying technology, so that one screen can be used for multiple purposes.
