VR Video: Operator Opportunities in a Booming Market

Core Content Overview

VR video is a rapidly growing market with diverse applications, including entertainment, sports, education, and enterprise. Operators are well-positioned to capitalize on this growth due to their existing infrastructure, distribution capabilities, and potential to integrate VR services into their broader offerings. The industry is evolving with advancements in technology and content delivery, creating new business models and opportunities for network providers.

Main Points and Key Information

1. VR Video Use Cases

• VR video is a key use case for operators, who often run video services themselves.
• It spans various domains such as cinema, sports, social media, live streaming, and gaming.
• Volumetric VR, which allows 3D interaction and movement within a scene, is emerging as a significant enhancement.

2. What is VR Video?

• VR video creates a fully immersive virtual environment where users can look around freely.
• It includes 360° video, 180° video, and volumetric video.
• 360° video is the most common form, with the user able to look in any direction.
• Volumetric video is more immersive and allows for interaction, but requires higher bandwidth.

3. VR Video: From Creation to Delivery

• The process involves 360 video acquisition, stitching, post-production, and delivery via CDN.
• Content is transformed and encoded at the CDN to suit the delivery device.
• Viewport-dependent delivery, where only the part of the video in the user's field of view is transmitted in high quality, reduces bandwidth requirements but requires low latency and real-time user feedback.

4. Image Quality and Bandwidth Requirements

• Current VR headsets require 50 Mbps for a good user experience.
• 4K VR video requires 50 Mbps, while 8K VR video may require 120–200 Mbps.
• 12K VR video (equivalent to 4K TV) requires up to 1.4 Gbps.
• As headsets improve in resolution, network capabilities must also evolve to support higher quality video.

5. Standards for VR Video

• H.265 (HEVC) offers better compression than H.264, supporting up to 8K resolution.
• MPEG is working on OMAF (Omnidirectional Media Format) for viewport-dependent delivery.
• Other standards include spatial audio (MPEG-D) and models of interactivity (MPEG-V).
• MEC (Multi-access Edge Computing) is being developed by ETSI and VRARA to support VR applications.
• IEEE is also involved in defining standards for VR and AR interactions.

6. VR Video Industry Trends: Service Traction

• VR video has seen sustained consumer interest, despite some initial hype.
• Major platforms such as YouTube, Facebook, and Vimeo have launched VR video services.
• The Olympics, Fox Sports, and other events have driven VR adoption in sports.
• Social networks and OTT platforms have played a significant role in popularizing VR content.

7. Case Studies

• Fox Sports: Launched VR sports app in 2016, offering immersive experiences for sports events. It has expanded coverage to include multiple sports and leagues, using partnerships with companies like NextVR and Intel.
• Olympics: The 2016 and 2018 Olympics featured VR coverage, with OBS distributing live VR content to rights holders. The 2020 Tokyo Olympics will also include VR.
• YouTube: Hosts over 850,000 360 videos and introduced 180° video in 2017. Popular content includes sports, music, and gaming.
• Facebook 360: Launched in 2015, it has grown to include over 1 million 360 videos and introduced live streaming and 4K support.
• Vimeo: Added 360 video in 2017, offering a platform for professional creators.

8. Business Models for VR Video

• Established providers (Fox, YouTube, iQiYi) are using VR to enhance their offerings without changing their core business model.
• Some are experimenting with new models, such as charging for VR content or exploring advertising.
• Operators can use VR to increase ARPU by offering immersive experiences and leveraging cloud technology to create compelling user propositions.
• B2B models are also emerging, with operators providing VR services to enterprises and other businesses.

9. Challenges in VR Broadcast

• Hardware: High-end headsets require higher resolution and better performance.
• Network: Bandwidth and latency are critical for delivering quality VR video.
• Content: High-quality, immersive content is in demand but requires significant resources to produce.
• Consumer Pain Points: Issues like headset design, comfort, and user experience impact adoption and revenue potential.

Opportunities for Operators

Operators have unique opportunities to address VR video challenges and drive market growth:

• Overcoming Bottlenecks: By improving network infrastructure, optimizing content delivery, and supporting better hardware.
• Business Models: Leveraging VR to increase ARPU, offering cloud-based VR services, and exploring B2B models.
• Partnerships: Collaborating with content creators, hardware manufacturers, and other tech firms to enhance offerings and reduce costs.

Key Takeaways

• VR video is a key use case with broad market reach.
• Network requirements are increasing as resolution and interactivity improve.
• Standards are evolving to support higher quality and more interactive VR experiences.
• Operators can play a central role in the development of VR by addressing technical and business challenges.
• The market is growing, with significant traction in sports, social media, and entertainment.
