The system includes packet buffers, a multiplexer, a packet substitution controller, a direct memory access (DMA) engine and a link list buffer controller. A method is also provided for substituting data packets-containing information of the same or different type-into a video data stream at variable rates using a selection mechanism driven by link list buffer control.
