Oct 15, 2025 – CUPERTINO, CA — TVU Networks delivered a complex multi-site broadcast solution connecting eight locations across two Chinese provinces for the simultaneous groundbreaking ceremonies of the Shanghai–Hangzhou High-Speed Railway (Zhejiang section) and the Wenzhou–Fuzhou High-Speed Railway. The event, held in Hangzhou and Fuzhou, marked a significant milestone in China’s coastal infrastructure development.
Technical Complexity at Scale
The broadcast presented substantial technical challenges. Eight venues spanning Zhejiang and Fujian provinces—including primary sites in Hangzhou and Fuzhou, plus additional locations in Wenzhou, Ningde, and Jiaxing—required simultaneous connectivity with broadcast-quality video and sub-second latency over public networks. Organizers needed perfect synchronization to ensure officials at different locations could jointly initiate the ceremonies in apparent unison, despite being separated by hundreds of kilometers.
TVU deployed an integrated solution centered on more than 30 TVU One mobile transmitters for signal acquisition, 20 TVU servers for onsite decoding, and TVU Grid for routing and distribution. Complete redundancy through dual configurations ensured zero-failure reliability throughout the event..
Proven Performance Under Pressure
At each site, TVU One transmitters leveraged the company’s patented IS+ multi-network aggregation technology, bonding multiple 5G connections into a unified high-bandwidth channel. This approach delivered stable, high-quality transmission even under variable public network conditions.
Live feeds routed through TVU Grid enabled point-to-multipoint distribution with frame-accurate synchronization across all eight locations. Local servers decoded incoming signals for live mixing and on-site projection, while directors used centralized monitoring interfaces to coordinate camera angles and ensure ceremony actions remained precisely aligned.
During the ceremonies, the system performed without interruption. Video quality remained consistently high across all sites, and timing control was exact enough to create the impression of a unified celebration—government leaders in different cities simultaneously breaking ground as if sharing the same stage.
Building on Field-Tested Expertise
The deployment builds on TVU’s track record in large-scale, high-stakes events. The company has previously supported the “Thinking India Today” global broadcast connecting 21 locations, the Hangzhou–Wenzhou HSR opening ceremony, China–Kazakhstan cross-border collaboration projects, and international live connections in Ningbo. This experience base informed the technical planning and execution for the dual-province railway groundbreaking.
TVU’s IP-based video networking technology continues to serve national infrastructure projects, international summits, and multi-site broadcasts where reliability and precision are non-negotiable. The successful execution of the Shanghai–Hangzhou and Wenzhou–Fuzhou ceremonies reinforces the platform’s capability to handle complex, geographically distributed productions at scale.
