Last July, the next generation video codec standard h.266/vvc was released. In short, h.266 further optimizes the compression, which can save about 50% of the data traffic.
However, just as the h.265/hevc standard was only supported by Apple’s IOS 11 four years after it was signed, today’s video codec is still dominated by h.264/avc, and h.266/vcc still needs considerable time to be promoted and adopted.
According to media reports, the jvet website of the joint video expert group shows that byte beating AVG (advanced video team) launched a video compression technology proposal in February this year, which can optimize the compression quality and save at least 13% of the storage and bandwidth.
In short, the core of the proposal is deep learning technology to build a filter (dam) to reduce video compression distortion.
The experimental results show that, compared with the latest h.266/vvc standard, the byte hopping dam solution can significantly improve the performance of video coding. The luminance signal Y can achieve a performance gain of 10.28%, and the performance gains of two chroma signals u and V are 28.22% and 27.97% respectively.
In other words, while the video quality is optimized, the data volume can be reduced by at least 13% (a 180 minute h.266/vvc standard high-definition video (1080p resolution), which requires about 3gb of data volume, and only 2.6GB after the application of new technology).
Tiktok’s AVG research results will also be upgraded through the BVC encoding, including video processing of App, video processing, cloud computing, cloud games and other infrastructure.
