摘要Rate control plays an important role in video coding, and most of the existing rate control schemes are based on the assumption that the video contents are uniform. However, for non-uniform video applications, such as screen content videos and movies, previous rate control schemes may cause severe quality degradation, since the bit allocation strategy is improper and the rate-quantization (R-Q) model parameters may extremely inaccurate. In this paper, firstly an adaptive bit allocation algorithm is proposed for the newest video coding standard high efficiency video coding (HEVC), next a key frame detection method is presented, and finally an accurate intra R-Q model, a model parameter adjusting strategy and a bit feedback strategy are developed for the scene change frame. Experimental results show that the proposed rate control method could achieve more accurate bitrates and better rate-distortion (R-D) performance than previous rate control methods.
