NTT Docomo has developed a 5G-ready platform capable of streaming 8K stereoscopic virtual reality, opening up significant new possibilities for immersive media.
While many consumers are still adopting 4K, the industry is already pushing toward 8K—an advancement that not only increases resolution but also enhances immersion for VR and large-format displays.
Docomo’s solution can stream high-resolution panoramic VR content from virtually any location over a 5G connection.
The system combines an 8K stereoscopic camera with 360-degree capture, a Yamaha-developed spherical 3D microphone that records 64 separate audio channels, multiple processing servers, and a 5G base station to handle transmission.
To manage the substantial processing and bandwidth requirements, the carrier employs a specialized 8K video encoder that outputs 60 frames per second, a frame rate chosen to reduce motion sickness and provide smoother VR experiences.
Multiple workstations process the camera’s nine 4K video feeds into two 360-degree 8K stereoscopic streams in real time. A separate server mixes the microphone’s 64 channels down into 36 channels of spatial audio. These video and audio streams are then compressed for efficient delivery over 5G networks.
The entire configuration is designed to enable live, high-fidelity VR broadcasts that retain both visual detail and accurate spatial sound.
Adoption of VR has been slower than early enthusiasts expected, but emerging technologies like 5G are addressing long-standing limitations.
Historically, VR’s adoption has been constrained by two main factors. First, hardware costs and high system requirements often meant a powerful PC was needed. Second, many VR setups were cumbersome and tethered users to a fixed location, limiting mobility and convenience.
Standalone headsets such as the Oculus Quest have begun to tackle the hardware and affordability barrier, while 5G connectivity promises to remove the tethering problem by delivering high bandwidth and low latency over cellular networks.
5G’s increased throughput, improved reliability, and reduced latency unlock new use cases for live, interactive applications—particularly live event streaming in immersive formats.
For example, millions of players tuned in to a live in-game concert by Marshmello in Fortnite, demonstrating the appetite for large-scale virtual events. Although that concert was not presented in VR, it highlighted audience interest in immersive live experiences and suggested a path forward for VR concerts, esports events, and other live attractions.
Systems like Docomo’s 8K stereoscopic streaming platform represent a step toward making such live VR spectacles feasible, by combining ultra-high-resolution capture, spatial audio, real-time processing, and 5G delivery.
