Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual desktop systems, the simultaneous use of graphics processing unit (GPU) for screen encoding and other processes leads to delays, reducing user operability due to increased response time.
Innovation Solution
An image processing apparatus that dynamically selects between moving image and still image transfer processes based on the frame rate and GPU processing load, optimizing screen transfer by using either moving image transfer mode or still image and moving image transfer mode to manage GPU resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the GPU is used for both screen encoding and other image processing tasks simultaneously, then the processing capacity and versatility of the system is improved, but the response time increases and user operability deteriorates
Solution Approach 1:
The patent segments the screen transfer process into two independent transfer processes: a first transfer process for moving image data and a second transfer process for still image data. This segmentation allows the system to handle different types of image data through separate pathways, preventing resource contention and reducing response time when the GPU is engaged in other tasks.
Solution Approach 2:
The patent implements dynamic selection between the first and second transfer processes based on real-time monitoring of GPU state and frame rate. The control process dynamically switches between transfer modes depending on system conditions, allowing the system to adapt to varying GPU availability and optimize response time under different operating scenarios.
2Ease of operation
If the frame rate of screen transfer is increased to improve user operability, then the responsiveness is improved, but the network bandwidth consumption increases
Solution Approach 1:
The patent separates screen transfer into moving image data transfer and still image data transfer processes. This segmentation enables the system to transmit only necessary image data at high frame rates while excluding redundant information, thereby improving user operability through smoother display without proportionally increasing network bandwidth consumption.
Solution Approach 2:
The patent changes the transfer parameters dynamically by selecting between different transfer processes based on frame rate and GPU state. When frame rate is high, the system optimizes the transfer process to maintain quality while managing bandwidth, and adjusts parameters based on real-time system conditions to balance user operability with network efficiency.
3Quantity of substance
If the system uses still image transfer mode to reduce network bandwidth, then the network efficiency is improved, but the image quality and frame rate performance deteriorates
Solution Approach 1:
The patent segments the transfer process into separate moving image and still image transfer pathways. This allows the system to use still image transfer mode for static content to reduce bandwidth while maintaining image quality through dedicated still image processing, and switch to moving image transfer mode when motion content requires higher bandwidth, thus balancing network efficiency with image quality.
