摘要

Rate control (RC) techniques play an important role for interactive video coding applications, especially in video streaming applications with bandwidth constraints. In this paper we propose a new BU-level rate control algorithm with ROI support and the associated architecture for H.264 and AVS by exploiting a new predictor model to predict the MAD value and target bits for hardware realization. The proposed algorithm breaks up the sequential processing dependence in the original H.264/AVS RC algorithm and reduces up to 80.6% of internal buffer size for D1 video encoding, while maintaining good video quality.
