Abstract
In this paper, a novel R-\(\lambda \) rate control algorithm is proposed. Firstly, different from the conventional R-\(\lambda \) rate control for the predefined bit ratio of the frame level rate control, an adaptive bit allocation ratio, which is mainly determined by mean bi-directional frame difference, is proposed for more reasonable frame level bit allocation. Then, according to the rate distortion optimization (RDO) process, a special relationship between frame \(\lambda \) and the mean coding tree unit (CTU) \(\lambda \) can be built. Finally, a CTU \(\lambda \) clipping method is proposed to get the optimal RDO of every CTU in a frame. The experimental results show that the coding quality of the proposed algorithm is increased by 0.35 dB at Random Access (RA) configuration and by 0.66 dB at Low Delay (LD) configuration.
