He has been engaged in the research and development of multimedia communication and broadcasting technologies. He has developed ultrahigh-definition video coding technologies that enable the representation detailed patterns of the 4K video realistic sensation at twice the conventional data compression ratio.
He has also expended significant effort in standardization work for the popularization of video coding technologies. He contributed to the development of the latest international video coding standard, High-Efficiency Video Coding (HEVC), in ISO/IEC and ITU-T by proposing the specifications of the ultrahigh-definition video coding technologies and coordinating their standardization activities with experts from around the world in his capacity as chairperson of several ad hoc groups. The HEVC standard is deployed in consumer electronics such as 4K TV receivers and smart phones owing to its high compression performance and interoperability. In the near future, it will be used in a wide range of applications such as internet-based visual services, as represented by smart TVs, for example.
Moreover, in 2014, he developed the HEVC-compliant 4K distribution encoding unit that compresses 4K video data to approximately 1/200 of the original size in real time. The encoding unit has been implemented in, for example, 4K broadcasting and 4K public viewing facilities, and therefore, is contributing greatly to launching next-generation broadcasting services all over the world.
For these achievements, he has received the 62nd Electrical Science and Engineering Technology Award from the Promotion Foundation for Electrical Science and Engineering, the 2014 International Standardization Incentive Prize of the Industrial Science and Technology Policy and Environment Bureau, and the Chief Award of the Industrial Standardization Business Award bestowed by the Ministry of Economy, Trade and Industry.
For his outstanding contributions, as described earlier, to visual information processing and communication fields, he well deserves the SUEMATSU-Yasuharu Award.
