Group Video Communication Network Device for Mixed VR and Non-VR Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current group video communication methods are restrictive, allowing only interactions between virtual users and limiting flexibility due to the lack of compatibility with both VR and non-VR devices, creating communication barriers between users with different types of devices.
Innovation Solution
A method and apparatus that determine the user type based on device information, processing video data accordingly to match the display mode, allowing users with different devices to participate in a group video session by converting virtual characters and environments to match the display capabilities of each user, enabling seamless interaction between VR and non-VR users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If group video session is designed for virtual users only, then the immersive VR experience is improved, but the adaptability to different device types deteriorates
Solution Approach 1:
The system applies different display processing methods to different user types. Virtual users receive processed video data optimized for VR immersive experience, while common users receive video data suitable for traditional display devices. This local differentiation maintains the immersive experience for VR users while enabling compatibility with non-VR devices.
Solution Approach 2:
The group video communication system is designed to serve multiple device types universally. The server can identify user device types and automatically adjust video processing parameters to ensure both virtual and common users can participate in the same session, making the system multi-functional across different platforms.
2Illumination intensity
If video data is processed for VR display mode, then the visual experience for virtual users is improved, but the compatibility with non-VR devices deteriorates
Solution Approach 1:
The system processes video data differently based on the target display mode. For VR users, the video is processed with parameters optimized for immersive display (e.g., stereoscopic vision, field of view adjustments). For common users, the same video data is processed with parameters suitable for traditional screens. This local quality adjustment ensures optimal visual experience for each user type without compromising overall compatibility.
3Adaptability or versatility
If the system supports both VR and non-VR users, then the flexibility of group video session is improved, but the system complexity increases
Solution Approach 1:
The server performs preliminary identification of user device types before video data processing begins. Based on this preliminary information, the system pre-configures the appropriate video processing parameters and display modes. This advance preparation simplifies the real-time processing by avoiding the need for complex dynamic adaptation during the video stream, thus managing system complexity while maintaining flexibility.
4Ease of operation
If virtual characters are converted to match display capabilities, then the communication barrier between device types is reduced, but the processing time increases
Solution Approach 1:
The system performs device type identification and video processing parameter configuration in advance, before the actual video transmission begins. This preliminary action reduces the processing time during live video communication by establishing the processing pipeline beforehand. The server pre-determines the appropriate conversion parameters based on user device types, minimizing real-time computational overhead while ensuring seamless communication between different device types.
Data Source
AI summary
A group video communication method and a network device are provided. A user type of each user in a group video session is determined according to device information of the user. The user type includes: common user indicating that the user uses a two-dimensional display mode when participating in the group video session, and virtual user indicating that the user uses a virtual reality (VR) display mode when participating in the group video session. Video data of the group video session is processed according to a video display mode indicated by the user type to obtain target video data of the user. The target video data is sent to a user equipment of the user during the group video session, so that the user equipment presents the target video data of the group video session in the video display mode indicated by the user type of the user.
