VR Surface Data Synchronization for Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality media provider systems face challenges in efficiently distributing high-quality virtual reality data to multiple users simultaneously, as they often transmit redundant and irrelevant data, leading to increased bandwidth usage and reduced immersion due to the need to send detailed data for all aspects of a 3D scene, which can be impractical.
Innovation Solution
The system customizes virtual reality data by selecting relevant surface data frame sequences based on user-specific experience parameters, generating tailored datasets that focus on detailed aspects visible to each user, reducing unnecessary data transmission and enhancing immersion.

Engineering Contradiction Analysis
1Manufacturing precision
If the system transmits detailed virtual reality data for all aspects of a 3D scene to ensure high quality and immersion, then the virtual reality experience quality is improved, but the bandwidth usage increases significantly making the system impractical
Solution Approach 1:
The system applies local quality by customizing virtual reality data transmission to match each user's specific viewing parameters (position, orientation, field of view). Instead of transmitting uniform detailed data for the entire 3D scene, the system selectively transmits detailed surface data frame sequences only for the specific local region that each user is currently viewing, while using lower quality or no data for regions not visible to that user. This resolves the contradiction by maintaining high experience quality for the relevant local area while significantly reducing overall bandwidth usage.
Solution Approach 2:
The system changes parameters by dynamically adjusting the level of data detail and transmission characteristics based on user-specific experience parameters. The system modifies parameters such as data resolution, frame rate, and spatial coverage to match each user's viewing conditions. This allows the system to transmit high-quality detailed data when needed (for the user's current view) and reduce data transmission when the same detailed data would be irrelevant to the user's perspective, thereby resolving the bandwidth quality contradiction.
2Manufacturing precision
If the system transmits detailed virtual reality data for all aspects of a 3D scene to ensure high quality and immersion, then the virtual reality experience quality is improved, but the system complexity increases
Solution Approach 1:
The system manages complexity by implementing localized data processing and transmission strategies. Instead of managing complex rendering and transmission for the entire 3D scene for all users, the system focuses computational resources on generating and transmitting detailed surface data frame sequences only for the specific local region relevant to each user's current view. This localizes the complexity to only where it is needed, reducing overall system complexity while maintaining high experience quality.
Solution Approach 2:
The system applies dynamics by making the data transmission and processing adaptable to changing user positions, orientations, and viewing conditions. The system dynamically adjusts which regions receive detailed data and at what quality levels based on real-time user state information. This dynamic adaptation simplifies system management by allowing a single unified system to handle multiple users with different needs without requiring separate complex systems for each user scenario.
3Loss of energy
If the system provides customized virtual reality data for each user to reduce bandwidth and improve efficiency, then bandwidth requirements are reduced, but the complexity of data selection and customization increases
Solution Approach 1:
The system applies preliminary action by pre-processing and organizing 3D scene data into structured surface data frame sequences that are ready for selective transmission. The system pre-divides the 3D scene into manageable regions and pre-associates these regions with user experience parameters, so that when a user connects, the system can quickly select appropriate data without performing complex real-time analysis. This preliminary organization reduces the complexity of real-time data selection while enabling customized low-bandwidth transmission.
Solution Approach 2:
The system achieves universality by creating a single multi-functional data management system that handles multiple users with different viewing parameters through a unified approach. The same system infrastructure and data structures serve all users by dynamically adapting to their individual needs, rather than requiring separate specialized systems for each user type. This universal system manages data selection and customization complexity centrally, distributing simplified data to each user while reducing overall bandwidth requirements.

AI summary
An exemplary virtual reality system includes a management device, a synchronization device, and a gatekeeper device communicatively coupled to the management device and the synchronization device by way of a network. The gatekeeper device is configured to receive, at a particular time, a frame of a surface data frame sequence that the gatekeeper device is responsible for processing. The gatekeeper device is also configured to transmit, to the synchronization device, the particular time at which the gatekeeper device received the frame, and to receive, from the synchronization device, a timeframe during which the gatekeeper device is to transmit the frame. The gatekeeper device is further configured to transmit, to the management device during the timeframe received from the synchronization device, the frame of the surface data frame sequence. Corresponding systems and methods are also disclosed.
