Key Information

1. VR Experience Levels and Network Requirements

2. VR/AR Technology Architecture

The VR/AR technology architecture is composed of five core fields:

• Near-eye display
• Rendering processing
• Perception and interaction
• Network transmission
• Content creation

These are further divided into three hierarchical layers, with the first layer being the core technologies and the second and third layers being more detailed technical components.

3. Key Technologies and Trends

• Near-eye Display:

  • High Angular Resolution and Wide FOV: These are essential for enhancing immersive experience and reducing the screen-door effect.
  • Dizziness Control: A major challenge, with solutions such as reducing latency, improving coordination between sensory inputs, and addressing vergence accommodation conflict (VAC).
  • Leading Screen Technologies: AMOLED, LCOS, and OLEDoS are key technologies in near-eye displays. AMOLED is widely used in VR devices due to its fast response time, low weight, and reduced blue ray radiation. LCOS and OLEDoS are favored for AR due to their high resolution and light efficiency.

• Perception and Interaction:

  • Tracking and Positioning: Core to VR/AR, especially for immersive experiences.
  • Environment Understanding: Based on machine vision, a key trend for AR.
  • Multi-channel Interaction: Enhances user engagement in VR.

• Network Transmission:

  • High Bandwidth and Low Latency: Critical for real-time VR experiences.
  • Access Network Trends: New Wi-Fi, 5G, and large-capacity PON are being developed to support VR.
  • Bearer Network Trends: Simple architecture, smart pipes, multicast on demand, and network isolation are important for efficient VR service delivery.
  • Low-Latency Data Centers: Necessary for cloud-based VR computing.
  • Optimization Techniques: Projection, coding, and transmission technologies are key to improving VR network performance.

• Rendering Processing:

  • Enhanced Algorithms: Deep learning-based rendering improves image quality and reduces rendering time.

4. Industry Ecosystem and Development Trends

• The VR/AR industry ecosystem is dominated by components/equipment, tools/platforms, and content/applications.
• Perception and Interaction, and Content Creation are the next development focuses.
• IPR Competition is a growing trend, with China and the US leading in patent applications.
• The VR/AR+ Era is emerging, where VR/AR technologies are integrated into various industries such as manufacturing, medicine, games, and media.

5. Strategic Recommendations for Telecom Operators

• Core Link in the VR/AR Industry Chain: Telecom operators play a vital role in ensuring the quality and popularization of VR/AR services.
• Driving Service Evolution: Operators are encouraged to evolve VR services from virtual cinemas to live VR and cloud-based VR.
• Development Recommendations:
  • Invest in high-quality content creation and perception interaction technologies.
  • Support network infrastructure that meets the high bandwidth and low latency requirements of VR.
  • Promote industry collaboration and IPR protection.
  • Develop cloud-based VR solutions and low-latency data centers.
