  • Publication number: 20160357493
    Abstract: A method and a device for synchronizing the display of video frames from a video stream of a video insertion of a video image source, which is simultaneously presented on two or more displays of a display wall. The synchronous, tearing free display is realized by means of a video frame queue for the video frames, a mediation function which is commonly used by the network graphics processors involved in the display of the video insertion and which, during a mediation period that extends over a plurality of vertical retraces of the display wall, determines which video frame is displayed by the displays and establishes a balance between the vertical display frequency and the video stream frequency, and synchronization messages which are sent before the start of a mediation period by a master network graphics processor of a display to the slave network graphics processors of the other displays.
