[Qoncept Inc.] Video Review System 'REFLEX' Officially Introduced at the 79th All Japan General Badminton Championships and S/J League 2025 TOP4 Tournament, Realizing a Rapid Challenge System

Qoncept Inc. (Headquarters: Miyamasuzaka Building 301, 2-19-15 Shibuya, Shibuya-ku, Tokyo 150-0002; CEO: Kenichi Hayashi; hereinafter 'Qoncept') is pleased to announce that its sports video review system 'REFLEX', developed in-house, was introduced as the official challenge system at the '79th All Japan General Badminton Championships' held at Keio Arena TOKYO on December 30, 2025, and the 'Badminton S/J League 2025 TOP4 Tournament' held at Yokohama BUNTAI from February 28 to March 1, 2026.

At these tournaments, 'REFLEX' was used for IN/OUT shuttlecock reviews (challenges) requested by players. Compared to conventional systems, it significantly reduced the time required for a ruling, achieving rapid reviews in under 10 seconds*, thereby contributing to smooth tournament operations without interrupting the excitement of the match.

■ Background and Results of the Introduction

While 'challenges' (video reviews) in badminton matches are crucial elements that can determine victory or defeat, there was an issue where the waiting time for a ruling disrupted the rhythm of the game. 'REFLEX', introduced this time, is a system characterized by a simple equipment configuration centered around an iPad Pro and an intuitive touch interface.

At the tournaments, umpires used 'REFLEX' to instantly check the relevant scene, make a judgment, and immediately broadcast the review footage (clip) to the large vision screens at the venue. With its unique operability, the review process, which traditionally took time, was drastically shortened to an astonishing speed of 'under 10 seconds'. This provided an accurate and fair match environment without keeping players, spectators, or viewers waiting.

■ Main Features of the Video Review System 'REFLEX'

1. Intuitive Touch GUI and Map-type Camera Selector
Leveraging the iPad Pro's touch panel, intuitive operations similar to a smartphone, such as pinch-to-zoom and swipe-to-scroll, are possible. Furthermore, it features a 'Map View' function (*patent pending) that displays a preview on the screen according to the actual camera placement, allowing instant selection of the optimal angle required for a ruling without hesitation.

2. Immediate Discovery of Ruling Frames and External Video Output of Ruling Scenes
With a smooth seek function, frames required for a ruling, such as the moment of landing, can be instantly identified. The ruling scene is created as a video clip on the spot and can be immediately output to the venue's large vision screen or broadcast feed via HDMI. Since this external output of the review video is processed within the same iPad Pro, no additional hardware or PC is required.

3. Simple and Flexible Equipment Configuration
The necessary equipment consists only of an iPad Pro, cameras, a PoE hub, and LAN cables, making for an extremely simple setup. The cameras support PoE (Power over Ethernet) and the NDI standard, performing power supply and video transmission through a single LAN cable, which significantly reduces the burden of setup and dismantling.

■ Future Developments

Following its success at these two tournaments, it is scheduled to be introduced in many future tournaments as the official judge assist system of the Nippon Badminton Association. Qoncept will continue to leverage the power of technology to ensure fairness in sports and contribute to improving their entertainment value.
