  • Video multiviewer systems
    Patent number: 10728466
    Abstract: A video multiviewer system is provided for use in the simultaneous viewing, at a viewing location, of video streams from multiple video sources, and comprises video prescaler means for deriving from each of multiple video input streams a respective set of one or more scaled video streams, the or at least some of the scaled video streams being of a different scale from that of the video input stream, the system further comprising a video stream combiner programmed or arranged to combine selected scaled video streams to enable the selected scaled video streams to be displayed at the viewing location, wherein the combiner and prescaler means are programmed or arranged to be linked together, in use, by means of a packet switched network via which said selected scaled video streams are relayed to the video stream combiner.
