| Abstract | Consistent video quality is important for video coding applications, which is also a popular optimization target for rate control. In this paper, a rate control scheme is proposed to reduce the fluctuation of video quality. First, we set up the optimization formulation of distortion and derive the distortion model by analyzing quadtree-based coding unit (CU) structure in high efficiency video coding (HEVC). Then the frame bit allocation algorithm is proposed by considering the interdependency. After the frame basic quantization parameter (QP) is obtained, the solution of optimization formulation finally regulates QP to maintain the consistent video quality. Experimental results show that the proposed rate control scheme can reduce the fluctuation of video quality up to 92.9% than benchmark, where the average reduction is 74.1% |
