This paper describes a coding control scheme for MPEG-2 which maintains the perceived video quality constant, and is suitable for real-time and low latency encoding. We have chosen a proportional integral derivative (PID) scheme for the controller, and we adopt the same approach in designing the particular PID feedback function. The main reason for using a PID feedback function is the good tradeoff that it offers between computational complexity, ease of design, and performance. We have chosen to use a new video quality metric called moving picture quality metric (MPQM). This metric models the human visual system and matches subjective evaluations correctly, outperforming existing quality metrics for video. Simulations results are shown for typical video sequences. A comparison with CBR encoding also is presented.
