Developed "Long-Distance Video Monitoring Technology"

Sharp has developed "Long-Distance Video Monitoring Technology" that uses AI to analyze and record video transmitted from distances of 5 to 10 km. This technology was developed as part of the "Research and Development of Ultra-Coverage Beyond 5G Wireless Communication and Video Coding Standardization Technology through Japan-US-Australia International Collaboration" (Note 1), commissioned by the National Institute of Information and Communications Technology (NICT), in collaboration with the Laboratory of Prof. Hiroshi Harada, Kyoto University (hereinafter, Kyoto University), the Laboratory of Prof. Yutaka Watanabe, Waseda University (hereinafter, Waseda University), and Asahi Broadcasting Oita Co., Ltd. (hereinafter, Asahi Broadcasting Oita).

Video analysis during a demonstration experiment targeting grazing cattle (classifying differences in cattle behavior by frame color (Green: Standing, Yellow: Grazing), and displaying changes in the environment at the top of the screen by comparing the current video (left) with the video from just before (right) (40 seconds prior in this experiment)).

This technology consists of Kyoto University's "Long-Distance Video Transmission Technology," which can transmit 4K video over long distances using a wireless transmission method employing ultra-high frequency (VHF band), and Sharp's "Dynamic Video Monitoring Technology," which performs real-time recognition of object behavior without prior learning. Compared to conventional technologies, this significantly reduces the preparation time required for AI video analysis. In the future, it is expected to be used in a wide range of applications, such as monitoring from remote locations like disaster sites and evacuation centers, and danger detection.

To confirm the usefulness of this technology, Sharp conducted demonstration experiments both domestically and internationally from March of last year to January of this year. In Japan, we demonstrated its applicability in various fields by grasping the behavior of animals kept in zoos and aquariums, and transmitting video from moving ships. Overseas, in collaboration with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia, we demonstrated its potential for deployment in various fields through a demonstration experiment monitoring grazing cattle from a remote location.

Currently, Sharp is promoting proposals at international standardization meetings for wireless communication and video compression to have the wireless communication and video compression technologies used in the developed "Long-Distance Video Monitoring Technology" adopted as international standards for the next-generation communication standard "Beyond 5G" and the next-generation video compression standard "Beyond VVC." We will continue to promote DX support through long-distance wireless communication and AI technology so that it can be applied not only to animals and ships demonstrated this time, but also to a wide range of fields such as transportation infrastructure and disaster countermeasures.

1. Achieved 4K video transmission over long distances (5-10 km) using "Long-Distance Video Transmission Technology" utilizing ultra-high frequency (VHF band).

2. The AI technology "Dynamic Video Monitoring Technology" identifies objects without prior learning and records changes in situations and behavior. Applicable to various video analyses with shorter preparation times.

3. Usefulness confirmed through domestic and international demonstration experiments.
