VR Display Segmentation for Bandwidth Resolution Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality display technologies face limitations in picture resolution due to the constraints of wireless transmission bandwidth, which restricts the high-definition experience required for immersive virtual reality experiences.
Innovation Solution
A method and apparatus that acquire user pose information, transmit it to a target device, and receive static and dynamic picture data through separate channels, allowing for local storage and real-time generation of display pictures, thereby reducing the data amount transmitted over wireless channels and improving resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used for virtual reality, then user experience is improved, but picture resolution deteriorates due to bandwidth limitations
Solution Approach 1:
The picture data is segmented into static picture data and dynamic picture data. Static picture data is transmitted through a first transmission channel and stored locally, while dynamic picture data is transmitted through a second transmission channel. This segmentation allows the system to take advantage of both wired and wireless transmission capabilities, resolving the contradiction between user experience and picture resolution.
2Manufacturing precision
If wired transmission is used for virtual reality, then picture resolution is improved, but user experience deteriorates
Solution Approach 1:
The transmission system is segmented into two channels: a first transmission channel for static picture data and a second transmission channel for dynamic picture data. This allows the system to combine the high bandwidth of wired transmission for static data with the mobility benefits of wireless transmission for dynamic data, resolving the contradiction between picture resolution and user experience.
3Manufacturing precision
If high-definition picture quality is pursued, then data transmission amount increases, but wireless transmission bandwidth becomes insufficient
Solution Approach 1:
Static picture data is extracted from the overall data transmission and handled separately through a dedicated first transmission channel. This extraction reduces the amount of data that needs to be transmitted wirelessly in real-time, allowing high-definition picture quality to be achieved without overwhelming the wireless transmission bandwidth.
Solution Approach 2:
Static picture data is transmitted and stored in advance before the virtual reality session begins. This preliminary action prepares the data locally, so that during the actual session, only dynamic picture data needs to be transmitted in real-time over the wireless channel, significantly reducing the real-time data transmission amount while maintaining high-definition quality.
