Byte beating initiates a video compressed technology proposal

In July last year, the next generation of video codec standard H.266 / VVC announced. Simply, H.266 further optimizes compression, and can save about 50% of data traffic. However, as the H.265 / HEVC standard has been signed by Apple iOS 11, the video codec is still H.264 / AVC occupies mainstream, H.266 / VCC also requires considerable time promotion and adoption. . According to media reports, JFET official website shows that byte beating AVG (advanced video team) initiated a video compressed technology proposal in February this year, which can save at least 13% of storage and bandwidth while optimizing compression quality . Briefly, the core of proposal is a deep learning technology to build a filter (DAM) of video compression distortion. The test results show that the DAM solution of byte beating can be significantly improved for video coding performance compared to H.266 / VVC, and the brightness signal Y can achieve 10.28% performance gain, two chroma signal u and v The performance gain also reached 28.22% and 27.97%, respectively. That is, while the video quality is optimized, at least 13% of the data volume (a high-definition video (1080P resolution of 180 minutes) (1080p resolution), about 3GB of data volume, application new It only needs 2.6GB after technology. It is reported that AVG's research results will also be put into applications through the upgrade of BVC encoders, including shake, watermelon video, today's headlines, etc. APP video content processing, and cloud computing, cloud games and other infrastructure areas.
