The opening ceremony of the16th Tianjin Gamescame to a successful close.

Behind the spectacular live broadcast, the complex RF environment of a large-scale stadium presented a demanding real-world test for wireless video transmission. In a venue filled with wireless devices and constantly changing shooting positions, maintaining a stable transmission link was critical to capturing every key moment of the ceremony.

Large Venues: A Tough Test for Wireless Transmission

Large sports venues are notoriously challenging environments for wireless transmission. High-density Wi-Fi networks, LED screens, lighting control systems, intercoms, and dozens of wireless camera systems can operate simultaneously, creating a highly congested RF environment.

At the same time, steel structures, stands, and other obstacles can cause signal reflection, blockage, and multipath interference, increasing the risk of video stuttering, packet loss, or even transmission dropouts.

In this kind of complex environment, the interference resistance and transmission stability of a wireless video system can directly impact the reliability of the live production workflow.

Thunder PRO-Duo Delivers Stable Transmission for Two Camera Positions

For the opening ceremony, the production setup included two types of camera positions: arail-mounted cameraand aroaming camera.

The rail-mounted camera moved back and forth along a predefined track to capture dynamic wide-angle shots of the stage. The roaming camera presented an even greater transmission challenge, continuously moving throughout the venue to follow the action. Constant changes in distance, obstacles, and signal conditions placed high demands on non-line-of-sight transmission and dynamic interference resistance.

Thunder PRO-Duo simultaneously handled wireless video transmission for both camera positions. With strong signal penetration and non-line-of-sight transmission capabilities, it maintained a reliable wireless link even amid steel structures, physical obstructions, and a highly congested RF environment.

Key capabilities include:

• Up to 1,000 m transmission range, supporting flexible camera deployment across large venues;
• Two wireless video streams over a single RF channel, enabling up to two systems to be deployed in the same environment while reducing spectrum competition between camera positions;
• H.265 encoding with support for up to 1080p60, delivering high-definition video with ultra-low latency for real-time live production;
• Simultaneous HDMI and SDI outputs, together withTally and RS232/422/485 serial data transmission, supporting PTZ camera control and seamless integration into professional live production workflows.

Proven in the Field: Stable Transmission in a High-Interference Environment

Throughout the ceremony, the rail-mounted camera captured sweeping views of the stage, while the roaming camera continuously moved through the venue to follow the action.

From wide shots of the entire stage to detailed close-ups, video feeds were transmitted smoothly and in real time to the production control room, withno frame loss or transmission interruptions throughout the event.

Every critical moment of the opening ceremony was captured and delivered reliably to the live production system.

For large-scale sports and live events, transmission stability is the baseline. In a highly congested RF environment, Thunder PRO-Duo delivers strong interference resistance and reliable wireless video transmission, helping production teams keep their live workflow running without interruption.

We will continue to advance wireless video transmission technology and bring reliable wireless imaging solutions to more sporting events, live productions, and large-scale activities around the world.
