Revolutionizing Broadcast – The Construction of a Professional 4K OB Van for RTHK
Radio Television Hong Kong (RTHK) embarked on a transformative project to construct a state-of-the-art 4K Outside Broadcasting (OB) Van, aiming to enhance its mobile broadcasting capabilities and deliver high-quality content seamlessly. RTHK partnered with BTL & Aerospace NLM Electric Vehicle Technology Co., Ltd., a leading OB Van manufacturer in Beijing, to bring this vision to fruition. This collaboration combined local broadcasting needs with international engineering standards, ensuring every detail met high expectations.
The OB Van features three specialized areas:
- Audio Room: Designed for optimal acoustics and ergonomic layouts for real-time sound mixing.
- Main Control Room: Equipped with 4K video switchers and advanced monitoring systems.
- Server Room: Houses high-performance servers with redundant systems for reliable broadcasting.
The project began with the shipment of a chassis from Europe, followed by meticulous construction in Beijing and rigorous quality checks before final assembly in Hong Kong. The OB Van’s compartments are engineered for sound and weather resistance, meeting Noise Criteria (NC) Level 55 to minimize acoustic interference, while extensive rain testing ensured durability against Hong Kong’s unpredictable weather. Safety was paramount, with all electrical systems certified by a Registered Professional Engineer (RPE), guaranteeing adherence to the highest engineering standards.
Conclusion
Now operational, RTHK’s 4K OB Van stands as a testament to innovation and collaboration. It sets a new benchmark in mobile broadcasting, highlighting RTHK’s commitment to delivering world-class content and leading the industry forward.
