Abstract
A new adaptive video rate control scheme that makes the perceived picture quality of the reconstructed video as uniform as possible for time-varying bandwidth channels is presented. The proposed scheme dynamically skips the frames or adjusts the quantization parameters in a frame-basis according to the frame coding mode (FCM). It exploits the human visual perception that human eyes are less sensitive to quantization noise in a rapid-motion video and to frame-skipping in a slow-motion video. Simulation results demonstrate that the proposed adaptive rate control scheme can provide a better-perceived picture quality than the existing method (TMN-8).
