Ali announced the first full self-developed 4K real-time hardware encoder XGH265

On November 13th, Ali announced the hard core behind the support of the Cat, the super high-definition live broadcast - the first full self-developed 4K real-time hardware encoder XGH265. Relying on this cloud hardware encoder, under the same video quality, 40% bandwidth is saved by the mainstream chip encoder, the traffic is less, the picture quality is clearer, let 4K, 8K video live broadcast really into reality. ▲ Figure: Ali first models, high-performance real-time hardware encoders XGH265 With the arrival of the 5G era, VR / AR, holographic video, cloud game, etc., the new application, such as video, has emerged. These applications need to consume a lot of traffic and bandwidth be the largest bottleneck. The key to reducing the video bandwidth is the video compression technology, its core-video codec, both to meet the high throughput requirements of video processing, but also to achieve extreme compression efficiency. The industry usually is to increase the number of CPU cores. Ali is achieved by self-studying the first ultra HD cloud on real-time hardware encoder XGH265, and achieves higher quality video live in lower resource costs. The XGH265 is developed by the Alife Tumbe XG Laboratory Video Hardware Team, supports 4K real-time H265 encoding and has 4K real-time high quality video pre-processing capabilities. In architectural design, XGH265 uses software and hardware synergistic innovation programs, which will be reduced, and the control logic is realized on firmware, and a new hardware and hardware synergistic algorithm is designed. At the same time, through video pre-analysis, adaptive search strategy decision-making technologies, XGH265 completed significant breakthroughs in hardware micro-frame structures. Based on these innovations, the XGH265 saves 40% code rate than the mainstream chip while ensuring ultra HD real-time processing, and retains a richer detail and clearer picture. ▲ Figure: Movie scene ▲ Figure: Cartoon scene It is understood that the XG Laboratory Union, Alibaba Cloud ECS and video cloud team completed the XGH265 in the first half of this year's comprehensive deployment on Alibaba Haotian Faas platform, jointly supporting Qingdao International Beer Festival, Youku "This is a street dance! "And double 11 cats late 4K live, etc. It is reported that XGH265 will fully underestimate Youku's HD high-definition live broadcast business, and open up new tracks in Ali Cloud's full hardware 4K transcodes. Previously, the XG laboratory depth participated in the development of a new generation of international video coding standards (VVC / H.266), saving nearly 50% of transmission flows under the same image quality, and became the main promoter of the industry. The XG laboratory will also launch a variety of commercial levels of hardware and software VVC codecs, bringing 4K / 8K high-definition live broadcast to thousands of households.
