Riedel Communications provided a fully integrated communications and commentary solution for the recently concluded 15th National Games of China, supporting 56 competition venues and four International Broadcast Centres (IBCs) across Guangdong, Hong Kong, and Macau.
Over the 30-day event, the system operated without interruption, enabling coordination for 56 broadcasting teams and 39 ultra-high-definition productions.
Lin Yuquan, Technical Director of the National Games RHB, said, “The 15th National Games marks the first time Hong Kong and Macau have participated as host regions. This presented unique challenges in coordinating communications across multiple locations.
“Riedel’s solution addressed these complexities with a system that ensured seamless connectivity between four IBCs and 56 venues. From deployment to integration, the technology enabled efficient collaboration among teams from all three regions. The reliability and performance of Riedel’s infrastructure set a strong technical benchmark for large-scale, cross-regional events."
Held from 9-21 November 2025, the Games brought together elite athletes from provinces, municipalities and special administrative regions to compete in 34 sports, including athletics, swimming, basketball, cycling, and gymnastics. The event also featured mass participation activities in 23 sports, making it a showcase of sporting excellence and community engagement.
The National Games introduced an innovative "one main and three branch" IBCs layout, with Guangzhou serving as the main signal hub linking three regional sub-centres in Shenzhen, Hong Kong, and Macau.
To meet the demands of this distributed architecture, Riedel deployed its Artist intercom platform as the backbone of the network. An Artist-1024 matrix at the Guangzhou IBC supported over 200 channels, including AES67/ST2110-30 IP transmission and MADI signal integration, while an Artist-128 handled dedicated commentary channels. Both matrices were linked via cascaded fibre connections, creating a redundant configuration for uninterrupted performance.
Across all IBCs, Riedel installed 28 RSP-2318 SmartPanels featuring AES67/ST2110-30 compatibility and PTPv2 clocking for precise synchronisation. Riedel also provided 13 CCP-1116 commentary panels for the opening and closing ceremonies and 13 major competitions.
Guillaume Mauffrey, Director of Sales, Asia, Riedel Communications, said, “The scale and complexity of this year’s National Games required a robust, flexible solution capable of bridging multiple regions.
“Our team worked closely with technical partners to design and implement a system that delivered reliable, real-time communication across all venues and broadcast centres. This deployment underscores Riedel’s expertise in managing large-scale, multi-node events and our commitment to advancing IP-based workflows for live production environments.”
