Joint Video Coding of MPEG-2 Video Programs Transmitted Over a Constant Bit Rate Channel Based on Rate-Distortion Estimation

摘要

In this paper we propose a joint video coding scheme for ensuring that picture quality of all the programs are nearly the same. To obtain this objective, we propose a joint video coding scheme using the rate-distortion estimation results. Experimental results show that our coding scheme gives higher and more stable picture quality than an independent coding scheme that encodes each program independently.
