Abstract

In this paper, we propose a bit-rate control algorithm for H.264/AVC using the rate and distortion model estimated by the histogram of DCT coefficients. Since the proposed algorithm induces the rate and distortion model from the current macroblock instead of the previous coded frame or macroblock, it can effectively prevent the fluctuation of the output bits especially when scene change occurs, while keeping the quality in same level.
