What It Takes to Move 8K in Real Time | WebRTC Meets Hardware Reality
Voices of Video with Yasuhiro Itakura and Takumi Minamoto from MISAO Network, hosted by Naoki Chigai from J21
8K video isn't just "more pixels." It's a different class of problem.
In this episode of Voices of Video, walks us through what it actually takes to move 8K over the open internet - from multi-link SDI ingest to real-time compression, and why traditional approaches fall apart at this scale.
The conversation dives into the intersection of WebRTC and hardware-accelerated infrastructure, where ultra-low latency delivery meets the realities of massive data volumes, unstable networks, and strict timing constraints. This is where the NETINT VPU becomes critical - offloading video processing from general-purpose compute and enabling consistent, real-time performance at 8K scale.
The result? A system capable of 8K60 transmission with ~300ms glass-to-glass latency - delivered directly to standard web browsers.
Not a lab experiment. A working architecture - built by partners like MISAO Network.
Yasuhiro Itakura - CEO at Misao Network
Yasuhiro Itakura is CEO of Misao Network, where he leads the design and deployment of advanced communication and video infrastructure. With a background spanning telecommunications, IoT systems, and field-based network engineering, his work focuses on building reliable, real-time systems in challenging environments. He has contributed to projects involving wireless mesh networks, sensing systems, and high-resolution video delivery. At Misao, Itakura drives the integration of WebRTC, hardware-accelerated processing, and scalable architectures to bridge the gap between experimental technologies and production-ready deployments.
Takumi Minamoto - CTO at Misao Network
Takumi Minamoto is a WebRTC engineer based in Japan, focused on building real-time video systems that operate reliably at scale. With a background in telecommunications and software engineering at SoftBank and Telecom Professional Service, he brings deep experience in low-latency streaming, network optimization, and system integration. Takumi’s work sits at the intersection of WebRTC and production infrastructure, where performance constraints, network variability, and real-time requirements must all be balanced to deliver stable, high-quality video experiences.
