In an object oriented video merging system for use in teleconferencing, at least an object from one discrete video stream is to be merged into a composite video output signal for return to a plurality of selected sources at each instant in time, and each object in each video frame is describable by a polynomial which defines a two-dimensional shape. Video processing units processing video data from a plurality of video sources on a frame-by-frame basis, and a backplane having at least a data bus, and a common video bus into which an object from one discrete video stream is merged at any instant in time from a respective video processing unit. Each video processing unit includes an object description generator, a video priority register, and a video selector for permitting an object from the video stream being processed by the respective video processor unit to be transmitted to the common video bus only if the priority of that video stream at any instant in time permits such transmission.
