A video multiviewer system may include a video input/output (I/O) controller, a system memory, and a graphics processing unit (GPU) comprising a GPU memory. The system may further include a central processing unit (CPU) for operating the video I/O controller to transfer video data to the GPU memory via direct memory access (DMA) without being stored in the system memory, and a display for displaying multiple video windows based upon video data in the GPU memory.
