Back on Track: Kiloview Brings End-to-End 4K NDI to the 72nd Macau Grand Prix

The atmosphere was electric at the historic Guia Circuit as the 72nd Macau Grand Prix roared back to life in November 2025. It followed a successful 71st edition, when Kiloview transformed the event’s traditional baseband AV system into a flexible IP workflow centered around NDI. With multi-protocol support and seamless integration, the system established a scalable and future-ready production foundation. Building on that achievement, organizers partnered with Kiloview again to further elevate the AV capabilities within the existing NDI architecture. For the 72nd edition featured four days of elite racing, they aimed even higher for the same 6.2-kilo street circuit—superior image quality, broader coverage, and greater system stability to meet the demands of an increasingly intense competition. Raising the Stakes: New Challenges for the 72nd Macau Grand Prix The 72nd Macau Grand Prix came with bigger expectations and tougher challenges. Beyond on-track excitement, the AV upgrade targeted wider action capture, crisp 4K visuals, and uninterrupted streams for on-site and global viewers.

• Doubled NDI PTZ Camera Deployment: Based on 60 signal sources, NDI PTZ cameras were scaled to 8 for twice the previous deployment, delivering broader coverage that eliminates blind spots and captures every high-speed angle.
• Full End-to-End 4K Workflow Requirement: Previously limited to HD and partial 4K feeds, all feeds now required true 4K native resolution to provide sharper details and an immersive experience that brings fans closer to the action than ever before.
• Streaming Disruptions Under Trackside Conditions: While the NDI-based IP architecture improved system flexibility, signal interruptions before encoding, such as HDMI/SDI instability, power fluctuations, or source reboots, could still disrupt RTMP sessions used for cloud streaming and cause visible interruptions for remote viewers.

These challenges went beyond simply adding cameras or bandwidth. The solution had to scale efficiently, and stay resilient within the same system even when sources dropped unexpectedly. Scaling Forward: How Kiloview Built on Proven NDI Foundations for Expansion Extending the proven success of the previous year, Kiloview focused on scaling and strengthening the existing NDI infrastructure through targeted upgrades, without adding unnecessary complexity or disrupting on-site workflows. Seamless Expansion for Increased Camera Coverage To accommodate the increased signal volume, Kiloview leveraged the previously deployed NDI CORE MAX matrix system to scale PTZ camera deployment without additional hardware. With high-density NDI input and output capacity andflexible routing capabilities, the system seamlessly absorbed the expanded sources while maintaining efficient multi-destination distribution for broadcast, refereeing, and production teams. Maximizing Existing N60 Power with 4K Workflow Continued to serve as the core processing node within the 4K workflow, Kiloview’s All-in-one Bidirectional Converter N60 is fully integrated with NDI 6.2 SDK. Its NDI High Bandwidth streams were enhanced to support 4:2:2 10-bit color depth, delivering broadcast-grade image fidelity with richer detail and precise color reproduction for every moment on the track. Fail-Safe Streaming with RTMP Auto-Recovery Building upon N60’s broad protocol compatibility, Kiloview optimized the its RTMP session management mechanism, introducing enhanced streaming resilience at the encoder level. During temporary HDMI or SDI signal interruptions:

• The N60 now maintains an active RTMP streaming session with the cloud server, with no downtime shown to viewers.
• As soon as the video source returns, the stream resumes instantly over the existing connection with virtually no delay.

Success on Every Lap: Seamless Coverage and Unmatched Viewing Experience The 72nd Macau Grand Prix concluded with seamless AV performance, delivering uninterrupted, high-quality coverage across the entire circuit. Both on-site and remote audiences experienced the race in unprecedented clarity and reliability.   By enhancing the existing infrastructure, Kiloview showcased the scalability of NDI-based solutions and the future-ready design of the AV system, delivering an elevated viewing experience today and setting a strong foundation for Macau Grand Prix broadcasts in the years ahead.
