화질 개선을 위한 새로운 비트율 제어 알고리즘
A New Rate Control Algorithm for improving picture quality
초록
Test Model15, which is used widely for the MPEG-2 bit rate control, has several problems such as non-unform picture quality, scene change and buffer underflow. Therefore, various algorithms have been developed to solve these problems. In this paper, we study various algorithms for the MPEG-2 bit rate control and compare their performances using software simulations. We also propose a new bit rate control strategy based on coded types of macroblocks within a picture.
