Background of Providing the Video Review System

In sports competitions, video review systems that allow for the confirmation of crucial game moments via video are utilized as a means to improve decision accuracy and ensure fairness in competition.

However, their implementation requires the establishment of filming systems and video review environments tailored to the specific sport, venue conditions, and operational needs on the day of the tournament.

Against this backdrop, the Company will provide a video review system for the "2025-26 LEAGUE H Playoffs" by leveraging SPIIDEO. By utilizing the flexible, cloud-based deployment features of SPIIDEO, and efficiently constructing and operating a video review environment that adapts to the conditions of each tournament, we will realize a system capable of quickly reviewing necessary scenes during matches.

This initiative marks the first collaboration between the Company and LEAGUE H.
