| Summary: | 碩士 === 國立中山大學 === 電機工程學系研究所 === 104 === With applications of video coding have come to play important roles in today’s world, it is necessary to improve the coding efficiency. Therefore, we based on game theory to develop two methods for HEVC: the I-frame assignment method and the frame level bit allocation in rate control. In the proposed I-frame assignment method, the encoded sequence will be divided into several subsequences. Each subsequence is regarded as a game. All GOP in a subsequence is further divided into several set of GOP. Each set of GOP is regarded as a player and compete for the number of I-frame. The optimal I-frame assignment will be determined based on the generalized Nash bargaining solution (NBS). In the proposed frame level bit allocation method, each frame is considered as a player and competes for the GOP level target bits. In addition, the dependency relationship between the frames located in difference TLs is employed to the development of equation. The optimal solution of bit allocation is solved based on NBS. Experimental results show that the proposed methods improve the coding efficiency for HEVC.
