Riedel Communications provided a fully integrated communications and commentary system for the 15th National Games of China, supporting 56 competition venues and four International Broadcast Centers (IBCs) across Guangdong, Hong Kong, and Macao. Over the 30-day event, the system operated without interruption, enabling coordination for 56 broadcasting teams and 39 UHD productions.
Yuquan Lin, technical director of the National Games RHB, said: “The 15th National Games marks the first time Hong Kong and Macao 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 November 9 to 21, 2026, 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 a ‘one main and three branch’ IBC layout, with Guangzhou serving as the main signal hub linking three regional sub-centres in Shenzhen, Hong Kong, and Macao. 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. These panels enabled direct, low-latency communication between production teams and rights-holding broadcasters. At the venue level, 56 NSA-002A adapters converted traditional four-wire signals into IP streams with latency under 10ms, ensuring real-time connectivity even during peak traffic periods.
Riedel also provided 13 CCP-1116 commentary panels for the opening and closing ceremonies and 13 major competitions. Each booth integrated pre-amplification and intercom functionality, allowing commentators to interact directly with production teams while maintaining clear audio for broadcast audiences.
