<p>Frame tearing in an arbitrarily large number of incoming motion video signals incorporated into a single composite display is prevented using as few as three frame buffers. Independently and concurrently for each incoming motion video signal, one of the frame buffers is reserved for writing captured pixel data, another is identified as storing the most recently completely captured frame, and one is identified as currently being read in forming a frame of the outgoing composite display. Frames of the outgoing composite display are collected from the multiple frame buffers accordingly to designations of the motion video signals of the read frame buffer for each.</p> |
