A Novel ρ-q/Distortion Model for H.264 Rate Control Algorithm

摘要：

Rate control aims to maximize reconstructed video quality while adapting coding bit rate to the fluctuating network bandwidth. This paper proposes an easy rate control algorithm for H.264 video coding based on a novel ρ-q/Distortion model, whose data line shows quite a pleasing goodness-of-fit. Experimental results have demonstrated that, compared with rate control mechanism suggested in H.264 reference software, the proposed model provides a better reconstructed visual quality with a coding gain up to 0.37dB as well as much smaller bit rate control error with a maximum reduced bit rate up to 2.04kbps.
