Virtual Visual Content Distribution via Edge Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for distributing virtual visual content in VR/AR technologies either result in user interaction delays due to remote processing or lead to overheating and reduced service life of user equipment due to high computational demands.
Innovation Solution
A method that sends different portions of virtual visual content to various devices based on change frequency, with static content processed in the cloud and dynamic content processed at edge devices closer to the user, reducing network burden and improving distribution efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If virtual visual content is distributed to remote computationally powerful devices for processing, then processing capability is improved, but user interaction delay increases
Solution Approach 1:
The patent segments virtual visual content into different portions based on change rates, with static portions processed remotely and dynamic portions processed locally at edge devices closer to users, thereby balancing processing capability with reduced interaction delay
Solution Approach 2:
The patent introduces edge devices as intermediary components between remote cloud servers and user equipment. These edge devices cache and process content portions, acting as mediators that reduce the distance for data transmission and minimize user interaction delay while maintaining processing power
2Loss of time
If processing is distributed to user equipment to reduce delays, then user interaction delay is reduced, but user equipment overheats and service life shortens
Solution Approach 1:
The patent divides processing tasks by segmenting content into static and dynamic portions, assigning static portions to remote devices and dynamic portions to edge devices, thereby preventing user equipment from bearing excessive processing loads that cause overheating
Solution Approach 2:
The patent extracts computationally intensive processing tasks from user equipment and relocates them to edge devices with sufficient processing power. This extraction removes the harmful processing load from user equipment while maintaining low latency through edge device proximity
3Reliability
If virtual visual content is distributed to all edge devices, then content availability is improved, but network burden increases
Solution Approach 1:
The patent applies local quality by distributing different content portions to different edge devices based on their characteristics and user proximity. Static content portions are distributed to multiple edge devices for high availability, while dynamic portions are selectively distributed, optimizing network resource allocation
Solution Approach 2:
The patent uses partial action by distributing only necessary content portions to edge devices rather than complete content sets. Edge devices receive specific content portions based on predicted user needs and device capabilities, reducing unnecessary network traffic while maintaining content availability

AI summary
Embodiments of the present disclosure provide a method for distributing virtual visual content, including: sending a first content portion in virtual visual content to be interacted in user equipment to a plurality of edge devices; selecting at least one edge device from the plurality of edge devices; and sending a second content portion in the virtual visual content to the selected at least one edge device, the second content portion having a higher change rate than the first content portion in the interaction. According to the embodiments of the present disclosure, a portion of virtual visual content can be distributed to selected edge devices in advance, and there is no need to distribute the virtual visual content to all edge devices, thereby saving network burden, reducing bandwidth requirements, and improving distribution efficiency.
