A video processing system can include a buffer, a packetizer block that is coupled to the buffer, and a buffer controller that is coupled to the buffer and the packetizer block. The buffer is capable of receiving and storing a video signal as video data. The packetizer block is capable of packetizing video data read from the buffer and sending packetized data to a node external to the video processing system. The buffer controller is capable of controlling an amount of video data included within each packet generated by the packetizer block.
