Abstract A dynamic rate allocation method is presented which is based on the compression rate of image source coder, channel rate, channel characters and their influence on the distortion of progressive image. The best channel rate is selected according to the optimal rate allocation criterion between the source coder and channel coder, which ensures to achieve the minimal end-to-end distortion.
