How Gnzo Delivered Multi-Angle Live Streaming at Scale with Wowza

Live streaming major events requires precision, reliability, and powerful infrastructure—especially when delivering innovative, multi-angle experiences to audiences worldwide. Tokyo-based Gnzo, known for their interactive streaming platform fvLIVE, needed a robust solution to stream the the largest marathon event in Japan. Here’s how Wowza Streaming Engine helped Gnzo meet this challenge. 

   

The Challenge: Multi-Angle Streaming for a Global Audience 

Gnzo’s platform, fvLIVE, empowers viewers to select their viewing angle from various live camera feeds, enhancing viewer engagement and control. For the large marathon event in 2020, Gnzo faced significant technical hurdles:

• Aggregating multiple RTMP feeds from mobile broadcast units and helicopters. 
• Synchronizing video streams precisely in real time. 
• Ensuring high-quality, low-latency streaming across devices. 
• Delivering adaptive bitrate (ABR) streams to handle large-scale viewer concurrency. 

Gnzo’s Innovative Solution Using Wowza 

Gnzo implemented Wowza Streaming Engine as the core of their hybrid cloud infrastructure hosted within AWS. Key components included: 

• Centralized RTMP ingestion: Wowza aggregated multiple live inputs from vehicles, motorcycles, and helicopters into a centralized cloud gateway. 
• Real-time synchronization: Timecode detection synchronized all video streams, enabling seamless switching between camera angles. 
• Adaptive bitrate encoding: RTMP inputs were transcoded efficiently into HLS adaptive bitrate streams, delivering optimal playback quality regardless of viewer device or network conditions. 
• High availability architecture: Wowza Streaming Engine was deployed across two AWS availability zones, ensuring redundancy, scalability, and uninterrupted streaming. 

Results: Reliable, Synchronized Multi-Angle Live Streaming 

Gnzo successfully delivered a groundbreaking viewing experience for the marathon event: 

• Streamed live synchronized multi-angle video from over six mobile and aerial feeds. 
• Provided thousands of viewers seamless, high-quality viewing through a Japanese CDN and OTT platform. 
• Enabled real-time switching between various live camera angles, significantly boosting viewer engagement. 

Yasuhiko Takano, Lead Streaming Engineer at Gnzo, highlighted the impact, stating: 

“Wowza’s flexibility and stream handling capabilities were critical to our success in delivering synchronized, multi-angle video for large-scale events like Japan’s largest-class city marathons.”
