Video contents can be seen wherever we are. Though they are already compressed down to 1/10 - 1/1000 from its original size, they occupy a considerable amount of file storage, network bandwidth and computer memory and other resources. It has been reported that the visual data in Internet protocol (IP) traffic, mobile video traffic accounted for 59% of all worldwide mobile data traffic in 2017 and will be 79% by 2022. IP video traffic accounted for 75% of all worldwide IP traffic in 2017 and will be 82% by 2022. This is why development of better compression technology has been eagerly demanded all time. ITU-T/ISO/IEC jointly developed the latest video coding standard, High Efficiency Video Coding (HEVC), in 2013. They have started the next generation video coding standard, called Versatile Video Coding (VVC) in April 2018. It was just finalized in July 2020. In this keynote, we first overview the ever-advancing history of video coding technology and standardization activities in the last several decades. Then we review latest standardization activities on video coding, including VVC. Then we further extend to several examples of our new approaches, real-entity-oriented coding in particular, to further enhance visual quality, immersive sensations and natural experience as well as compression performance.
