Abstract
The emergence of high-resolution video formats such as 4K/8K and sophisticated mobile devices has caused a large increase in video traffic. For the efficient transmission and storage of large amounts of video data, a highly efficient video coding algorithm is desired. However, current video coding algorithms, as typified by H.264/AVC, are now mature, making it difficult to expect large future improvements. In response to the increased need for such an algorithm or please specify raised expectahons of what? ISO/IEC and ITU-T have developed a novel video coding standard called High-Efficiency Video Coding (HEVC). In this paper, we overview the process of standardization, the technological features of HEVC, and the improvement of coding performance. In our overview of the technological features, which is the main part of this paper, we describe the problems of the conventional method (H.264/AVC), the algorithm adopted in HEVC to solve each problem, and the mechanism that solves each problem.
