Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent terminals, such as cellular phones, cannot effectively run high-quality virtual reality applications due to performance limitations related to volume and power consumption.
Innovation Solution
A video conversion method and apparatus that acquire a video stream from a high-performance terminal device, perform format conversion, and output it to the intelligent terminal for display, allowing the intelligent terminal to handle only the display without running the application, thus utilizing a high-performance device as the video source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual reality applications are run directly on intelligent terminals like cellular phones, then the device portability and accessibility are improved, but the processing performance and quality of VR experience deteriorate due to limited computational power and power consumption constraints
Solution Approach 1:
The system divides the VR processing tasks into two segments: the intelligent terminal handles display and user interaction, while a separate high-performance terminal (PC or game console) handles the computationally intensive VR application execution and video stream generation. This segmentation allows each component to operate within its performance capabilities.
Solution Approach 2:
A video conversion apparatus acts as an intermediary between the high-performance terminal and the intelligent terminal. It receives the video stream from the high-performance terminal, performs format conversion to match the intelligent terminal's display capabilities, and outputs the converted stream. This intermediary resolves the incompatibility between the high-performance video source and the mobile display device.
2Reliability
If high-performance terminal devices are used to run VR applications, then the processing performance and visual quality are improved, but the device portability and cost increase
Solution Approach 1:
The system separates the heavy computational workload from the portable display device. The high-performance terminal (PC or game console) remains stationary and handles all intensive processing, while the intelligent terminal maintains its portability and serves only as a lightweight display and input device.
Solution Approach 2:
Instead of running the full VR application on the mobile device, the system creates a video stream copy of the VR rendering from the high-performance terminal and transmits it to the intelligent terminal. This allows the mobile device to display VR content without needing to perform the computationally intensive rendering itself.
3Adaptability or versatility
If format conversion is performed on video streams, then the compatibility with different display devices is improved, but the processing time and computational overhead increase
Solution Approach 1:
The video conversion apparatus is pre-configured with knowledge of the intelligent terminal's display parameters (resolution, refresh rate, color format). The format conversion is performed continuously in real-time as video frames are received, with the conversion parameters already optimized for the target device, minimizing processing delays.
