  Abstract

It is required to control the picture quality among video sources when the multiple video sources are together transmitted through the channel of fixed bandwidth such as satellite and terrestrial broadcasting. This paper presents a control method to keep the uniform picture quality among the video sources. We first find a model of distortion and bitrate for the multiplexing system of multiple sources. Then we allocate the bitrate to each source for uniformly divided picture quality among the sources by using the distortion-bitrate relationship for the real-time implementation without time delay. It is shown by simulation that the proposed quality control method can keep almost uniform picture quality among the sources in comparison to the conventional control method.
