Osaka, Japan, September 8, 2025 – Panasonic Entertainment & Communication Co., Ltd. announced today that its IT/IP platform KAIROS played a pivotal role in the successful live broadcast of Beethoven’s 9th with a cast of 10,000, a major event held in April to celebrate the opening of Expo 2025 Osaka, Kansai, Japan. The production, one of the world’s largest IP-based remote broadcasts to date, leveraged an all-photonics architecture powered by the Innovative Optical and Wireless Network (IOWN), which is operated by Japanese telecom giant NTT. The exceptional operational reliability and flexible system architecture of KAIROS contributed greatly to the project’s success.
Instead of using conventional outside-broadcast vans, the production adopted a fully remote workflow. Live signals from 21 cameras and 64 audio channels were transmitted in real time over approximately 40 kilometers—from the Expo venue along the Osaka waterfront to the main sub-control room at the headquarters of Mainichi Broadcasting System, Inc. (MBS) in downtown Osaka. IOWN technology was used for transmission, NTT West, Inc. provided technical support and KAIROS was chosen for its seamless compatibility with IOWN. The exceptional operability and stability of KAIROS played a key role in the success of this unprecedented large-scale remote production. The event’s technical success highlights the potential of KAIROS for advanced video production and sets a significant technological precedent for future expos and international events.
Panasonic is committed to supporting creators who deliver powerful, emotional experiences through video by offering next-generation production solutions centered on KAIROS.
