Relative Frame Rate Benchmark for Remote Desktop Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a virtual desktop infrastructure (VDI) architecture, measuring user experience in terms of display quality is challenging due to the remote execution of applications and the need for a standardized method to assess the visual quality of displays across different endpoint devices.
Innovation Solution
A method is introduced to measure display quality by comparing the screen seen by the user on a client device with the baseline screen on the server, using relative frame rate and overall image quality scores, which involve calculating frame rates and image quality scores based on timestamp videos and frame similarity analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display quality is measured in remote desktop environments, then user experience assessment is improved, but measurement complexity increases due to remote execution and diverse endpoint devices
Solution Approach 1:
The patent introduces a benchmark application as an intermediary component that runs on both server and client devices. This benchmark application serves as a mediator to capture and compare display outputs, enabling standardized measurement across diverse endpoint devices without requiring complex integration with each device's native display system.
Solution Approach 2:
The patent transforms the abstract concept of display quality into measurable parameters by capturing frame rates and image quality metrics. By converting visual quality assessment into quantifiable data (frame rate comparisons, image similarity scores), the system enables objective measurement while simplifying the complexity of subjective quality evaluation.
2Measurement precision
If frame rate comparison is used to assess display quality, then measurement objectivity is improved, but computational requirements increase
Solution Approach 1:
The patent extracts only the essential elements needed for quality comparison by using timestamp videos as a controlled test signal. Instead of analyzing all screen content, the system isolates and compares only the timestamp video output, reducing computational energy while maintaining measurement objectivity through targeted frame rate and image quality analysis.
3Measurement precision
If standardized measurement method is implemented across diverse endpoint devices, then measurement consistency is improved, but system adaptability requirements increase
Solution Approach 1:
The patent creates a universal measurement approach by designing the benchmark application to function across multiple endpoint device types (desktops, laptops, tablets, smartphones). The same benchmarking methodology and comparison logic are applied universally across all devices, ensuring measurement consistency while adapting to different form factors through a standardized interface.

AI summary
A method is provided to measure a relative frame rate of a remote desktop on a first computer and accessed by a second computer. The method includes playing a video timestamp on the remote desktop at the first computer where the video timestamp includes unique timestamps, screen capturing the remote desktop at the first computer and the second computer, determining a first frame rate at the second computer based on the screen capturing the remote desktop at the second computer, determining a second frame rate at the first computer based on the screen capturing the remote desktop at the first computer, and determining the relative frame rate as a ratio between the first and the second frame rates.
