Efficient Rate Control Method for Logo Insertion Video Coding in HEVC
In order to improve the network transmission stability of logo inserted video, an efficient rate control method for HEVC logo insertion is proposed in this paper. Based on the acceleration algorithm, the proposed mehtod optimizes bit allocation process in region and CTU level. First, each logo inserted video frame is separated into different regions to stop pixel error propagation. Then bits for different regions are allocated according to their coding characteristics. At last, target bit of CTUs are adjusted according to the video content information. Experimental results show that the proposed rate control method can achieve 4.46% BD-Rate saving on average with only 2.26% speed loss compared with the acceleration algorithm.
