TVU One Powers Seamless Live Coverage of Asian Beach Games Torch Relay Across Land, Sea, and Air
14 units deployed to deliver uninterrupted multi-camera broadcast across 10.5 km of beach, urban, and maritime terrain in Sanya, China
View Related ProductsSANYA, China — March 30, 2026 — The flame-lighting ceremony for the 6th Asian Beach Games took place at Tianya Haijiao in Sanya at 7:30 a.m., with the torch lit at the historic Southern Flame Lighting Platform — the same site used during the 1990 Beijing Asian Games. After 36 years, the sacred flame once again rose from this landmark, launching a 10.5-kilometer relay across the sandy shores, city streets, and open waters of Sanya Bay.
As the first major international multi-sport event hosted in Hainan since the official launch of its free trade port operations, the Asian Beach Games has attracted significant global attention. Sansha TV was tasked with providing full live coverage of the flame-lighting and torch relay, and turned to TVU Networks’ TVU One mobile transmitters to power the entire outdoor broadcast.
The Challenge: Multi-Camera, Long-Distance, Cross-Terrain Live Broadcast
The torch relay route was designed to showcase the best of Sanya. It began at the flame-lighting site at Tianya Haijiao and continued with a 4.2 km beach run along Sanya Bay, followed by a 3.8 km route through city streets, and culminated with a 2.5 km maritime leg from Phoenix Island Marina to the Sanya International Yacht Center. The relay combined beach running, urban relay, and open-water transport — a production challenge that demanded reliable, real-time signal capture and transmission across radically different environments.
Sansha TV’s production team needed to cover a wide range of camera positions: the full flame-lighting ceremony, the starting-line departure, beach tracking shots along Coconut Dream Corridor, urban street segments, the maritime relay from Phoenix Island to the yacht center, the closing flame-collection ceremony, drone aerial panoramas, and high-rise fixed overview cameras. These positions were spread across a vast area with frequent scene changes and long distances between them — far beyond the reach of traditional wired or satellite broadcast setups.
The Solution: 14 TVU One Units Keep Every Angle Connected
Sansha TV deployed 14 TVU One mobile transmitters to cover all key camera positions. Worn as backpacks, the units allowed camera operators to run alongside torchbearers on the beach, navigate through city streets, and ride aboard yachts on the open sea — all without the constraints of cables or concerns about signal loss.
Multi-camera coordination: With multiple TVU One units operating simultaneously, each assigned to a specific angle — flame lighting, torchbearer tracking, drone aerial, and rooftop overview — the control room director could switch seamlessly between feeds, offering viewers a comprehensive perspective of the relay.
Cross-terrain signal stability: The relay passed through beaches, highways, and open water, each with unpredictable network conditions. TVU One’s ISX inverse multiplexing technology aggregates multiple carrier 5G/4G connections simultaneously, dynamically managing data flow to maintain stable transmission even during rapid scene transitions.
Continuous mobile tracking with zero dropouts: Over a relay route spanning several kilometers, camera operators needed to move continuously while shooting and transmitting. TVU One’s lightweight form factor and robust transmission capability made “run, shoot, and transmit” a practical reality with no need to stop or swap equipment mid-route.
Why TVU One?
Live broadcasting a torch relay for a major outdoor sporting event represents one of the most demanding challenges in mobile production. It requires equipment that delivers extreme mobility, multi-camera coordination, stability in complex network environments, and extended battery life — all at once.
TVU One was built for exactly this scenario. Powered by TVU’s patented ISX inverse multiplexing technology, it can aggregate up to 12 network connections — including 5G, 4G, Wi-Fi, and wired Ethernet — into a single high-bandwidth transmission pipeline. Even in signal-congested coastal areas or crowded urban zones, TVU One ensures smooth, high-quality video delivery. Combined with HEVC smart VBR encoding and bidirectional FEC error correction, TVU One achieves high-resolution, low-latency audio and video transmission with end-to-end latency as low as 0.3 seconds.
From the solemn flame-lighting ceremony to torchbearers sprinting along turquoise shores, from sweeping drone views of Sanya Bay to dynamic footage of yachts cutting through the waves — 14 TVU One units ensured Sansha TV captured every moment of the relay without interruption.
The March 30 torch relay served as the curtain-raiser for the 6th Asian Beach Games, set to officially open on April 22. Behind the scenes, TVU One provided the technological backbone for the event’s first-mile broadcast, delivering reliable, real-time coverage as Sanya presented its vision of coastal sports excellence to all of Asia.
