At the venue, the number of staffs involved in the shooting was reduced as much as possible. One fixed-point 8K camera projecting the entire stage from the audience seat, and one 4K camera on the stage for shooting the conductor were installed. Two cameras were remotely controlled from the editorial booth.
Video shot from the front by 8K camera was segmented in HD using a Tamazone Workstation. Beautiful video image can be segmented in real time without deteriorating the image when zooming. We sent out total of 4 perspectives by switching over the following 5 perspectives: (i) a bird-eye view of the stage, (ii) 3 segmented images, and (iii) HD camera on the conductor. This is a system that can be operated by one staff member at minimum, and without the need of a cameraman at audience seat.

The distribution technology “Lumiere” by Nekojarashi Inc. was used for the video distribution. A four-screen composite of HD images was distributed in the form of 4K, and viewers were able to access from their own devices, such as PCs, tablets, and smartphones, and to select their preferred viewpoints. We believe that the needs of viewers to freely select images in line with own preferences, rather than a fixed view, will continue to rise.
The “Live Extreme” of Korg Inc. was used with audio data. With its uncompressed audio coding technology, we could distribute complex music tones of multi-instrumented composition in a quality close to the original sound.

We have received comments from those who watched the distribution:

• “I felt fresh to clearly see the performer’s expression without a blur, which we don’t usually see from the audience seat.”
• “Enjoyed watching the video I selected for the desired time, and there was no stress of delay when switching the screen.”

Astrodesign will continue actively to provide technical support for a rich art experience by utilizing 8K technologies.

The SINET6 opening ceremony was held on May 30, 2022, the first day of the NII Academic Information Infrastructure Open Forum 2022.

SINET6 is an academic information network constructed and operated by the NII. SINET6 is an upgraded version of SINET5, with a nationwide 400Gbps ultra-high-speed network, support for mobile networks such as 5G, and enhanced international connectivity, etc. It will not only support increasing communication volume, the broad development of IoT-related research, and expanding international collaborative research, but will also serve as the foundation for the data-driven society of the future. It will also serve as a foundation for the data-driven society of the future.

The ceremony included speeches by the concerned parties, an opening ceremony, as well as lectures and an appreciation ceremony related to SINET6.

Before and after the SINET6 opening ceremony, 8K video transmission was performed, connecting the Ginoza DC (data center) in Okinawa to the Academic Center in Tokyo, which houses the NII, via the SINET6 circuit network. Live 8K video from the Ginoza DC and 8K content reproduced from the Ginoza DC were transmitted to the Hitotsubashi Auditorium, the venue for the opening ceremony, and projected onto a 400-inch screen installed in the auditorium using an 8K projector.

In addition to the view of the Okinawan ocean from the Ginoza DC, ceremony participants were able to view 8K 3D images played back from an 8K recorder brought into the Ginoza DC and displayed in the Hitotsubashi Auditorium. The projector was also used for video presentation and display of materials during the ceremony.

At Ginoza DC, the CCU was installed at a location extended approximately 200m from the outdoor camera head AB-4830 using optical transmission equipment OT-5902/OR-5903.

A video switcher was used to switch between the camera’s live output and 8K content played back on the 8K SSD recorder HR-7518-A.

The output from the video switcher was converted to an ST 2110 compliant signal using the IG-5114 8K IP gateway for IP transmission, and the video received at the Hitotsubashi Auditorium side was displayed on the INSIGHT Laser 37000 8K projector.

In early October 2021, at an official game between the Chunichi Dragons and the Hiroshima Toyo Carp held at the Vantelin Dome Nagoya, we conducted a demonstration of our marketing and security platform “ASCA” with Casley Holdings,Inc. and Abit Co. Ltd.

Astrodesign’s 8K camcorder was used to capture 8K video of the entire field from a bird’s eye view behind the back net.
The captured images were checked on an indoor 8K monitor and transmitted at high speed and low latency via ABIT’s local 5G network.
In addition, data analysis was performed using CASLEY’s high-speed technology and AI.
Recognition accuracy that could not be captured with a conventional HD/4K video or transmission over 4GLTE was achieved.

・Real-time data distribution to mobile devices
・Ordering of goods from the audience using object recognition technology
・Detection of seat density and hazardous conditions
・Estimation of back screen viewing time

We confirmed that various solutions can be realized starting from video images such as the above.

It is a new service business model by Astrodesign, Casley Holdings,Inc., and AIC-VISION Corporation, utilizing advanced technologies such as 8K video equipment + 5G + AI analysis platform, etc. The project has been selected by the Tokyo Metropolitan Small and Medium Enterprise Promotion Agency as a “Business Support Project for Innovative Services in 2048,” and aims to become a highly competitive business in the future as a service that combines innovative equipment and business models that have never been seen before. In the future, we intend to automate the system and expand the service to the entertainment field and commercial facilities, in addition to sports.
