What is HEVC? HEVC Introduction

What is HEVC? It is the abbreviation of High Efficiency Video Coding, which is a new video compression standard that will improve the compression efficiency of video. Compared with the existing video compression standard H.264/AVC, it can more than double the compression efficiency, and can support ultra-high-definition video with 4K resolution and even 8K resolution.

In short, video compression is essential for us to enjoy audio-visual entertainment behind a technology. Take the TV example. In the past, due to the underdeveloped compression technology, the video could not be compressed to a small enough. Therefore, under a certain bandwidth, people can only watch several channels. Nowadays, with the continuous development of compression technology, the compression ratio of video has already made a leap. Now we are able to watch TV shows on hundreds of channels, thanks in large part to the advances scientists have made in video compression technology.

On January 26, 2013, HEVC officially became the internationally certified video coding standard. At the same time, this also indicates that the video compression technology has taken a new step. The HEVC compression scheme can greatly improve the compression efficiency of 1080P video content, which means that a large amount of network bandwidth can be saved while maintaining the quality of video content. For consumers, we can enjoy higher quality 4K video, 3D Blu-ray, HD TV content on the Internet.

Microsoft Research Asia self-built homes at the beginning, continue to make breakthroughs in video compression technology. Back in 2000, Li Shipeng, a researcher at Microsoft China Research Institute, and his research team submitted the "Error Detection and Fault Tolerance" program to the 54th International Conference on MPEG, and officially obtained it as an MPEG International. Part of the standard. This is the first proposal that the Chinese delegation has entered the international standard in history.

In the HEVC video standard, the research team of Microsoft Research Asia contributed a total of 33 technical proposals after a long period of research and technology accumulation, and led the screen content coding. ).

HEVC standard-setting process, has been actively involved in numerous industry companies, many of whom are industry leading companies. Today, major world-class chip vendors (such as Intel, Qualcomm, and MediaTek) are actively developing and upgrading HEVC real-time encoders. We believe that this technology will lead everyone into a new era of 4K video in the near future to revolutionize our audio-visual entertainment experience.
