摘要
为满足高清及超高清视频兴起后,人们的生活社会需求,2020年发布的多功能视频编码(Versatile Video Coding,VVC)在高效率视频编码(High Efficiency Video Coding,HEVC)的基础上进行了改进。VVC实现了在相同图像质量的条件下提升视频压缩率的目标。本文针对HEVC以及VVC中的帧内预测部分进行研究比较,并进行视频帧内编码对比测试。最后,通过测试得到以下结论:VVC较HEVC有22.21%的码率节省,可进一步提升视频压缩性能。
In order to meet people’s living and social needs after the rise of HD and UHD video,The versatile video coding(VVC)released in 2020 is highly efficient in video coding(high efficiency video coding,hevc).VVC achieves the goal of improving video compression rate under the condition of the same image quality.This paper studies and compares the intra prediction part of hevc and VVC,and makes a comparative test of video intra coding.Finally,through the test,the following conclusions are obtained:VVC has 22.21%bit rate savings compared with hevc,which can be further improved Step to improve video compression performance.
