Host Media Processing for Guest OS Color Space Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The performance discrepancy between host and guest operating systems in media processing due to differences in color space formats results in inefficient media data conversion, with the guest system's less performant media processing components lacking access to hardware-accelerated functionality.
Innovation Solution
A host operating system provides access to its more performant media processing component via an API, allowing the guest system to request and utilize hardware-accelerated color space conversion, using shared memory and a virtualized instance of the host component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guest operating system uses its own media processing component, then it maintains system independence and compatibility, but media processing performance deteriorates due to lack of hardware acceleration
Solution Approach 1:
The patent introduces a media processing component on the host operating system that acts as an intermediary between the guest operating system and the hardware-accelerated media processing capabilities. The host component receives requests from the guest system, processes the media data using hardware acceleration, and returns results to the guest system, thereby enabling high-performance media processing while maintaining guest system independence
Solution Approach 2:
The patent creates a virtualized copy of the host operating system's media processing component that is accessible to the guest operating system. This copy allows the guest system to utilize the host's hardware-accelerated media processing capabilities without requiring duplicate hardware or compromising its own system architecture
2Productivity
If the host operating system duplicates its media processing component for the guest system, then the guest system gains access to hardware-accelerated functionality, but resource overhead and system complexity increase
Solution Approach 1:
The patent merges the media processing functionality by allowing the host operating system's media processing component to serve both the host and guest operating systems. Instead of creating separate duplicate components, the host component handles media processing requests from both systems, reducing resource overhead and simplifying the overall system architecture
Solution Approach 2:
The host operating system's media processing component is designed to be universal, capable of handling media processing requests from both the host system and guest systems. This multi-functional approach eliminates the need for separate components and reduces overall system complexity while maintaining high performance
3Use of energy by moving object
If the guest operating system lacks a media processing component, then system resource consumption is reduced, but media processing functionality becomes unavailable
Solution Approach 1:
The host operating system provides self-service by offering its media processing component capabilities to the guest operating system. The guest system can request and utilize the host's media processing resources when needed, allowing the guest system to maintain a lightweight configuration while still accessing advanced media processing functionality on demand
Data Source
AI summary
The techniques disclosed herein enable a guest operating system (OS) to access and use a color space conversion component on a host OS. The guest OS provides, via an application programming interface, a request for the host OS to generate media data in a color space format that is used by the guest OS. To generate the media data, the host OS uses a color space conversion component on the host OS, which is more performant than a corresponding color space conversion component on the guest OS because the color space conversion component on the host OS has access to hardware-accelerated functionality. Accordingly, the color space conversion component on the host OS converts media data into the color space format that is used by the guest OS, and stores the media data in memory that is accessible to the guest OS.
