Stream Manager Layer for Platform-Independent Multimedia Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content processing technologies face challenges in platform compatibility, prioritization of content processes, and efficient resource management, leading to increased development complexity and decreased CPU resource utilization when handling multiple content processes simultaneously.
Innovation Solution
A layer providing a generalized interface for higher-order software modules to manage resource allocation and prioritize processes across different platforms, allowing for independent operation and unified resource management through a single execution context, such as a thread or process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content processes are implemented using platform-specific device drivers in the OS kernel space, then high-speed execution and desired performance are achieved, but platform compatibility decreases and development complexity increases
Solution Approach 1:
The patent introduces a stream manager as an intermediary layer between the application and platform-specific device drivers. This stream manager provides a unified interface for managing multiple content processes, while the actual platform-specific operations are handled by underlying device drivers. This allows the system to maintain high execution speed through kernel-space operations while improving platform compatibility through abstraction.
Solution Approach 2:
The patent segments the content processing system into distinct functional modules: a platform-independent stream manager that handles process creation, priority management, and resource allocation, and platform-specific device drivers that handle actual data processing. This segmentation allows each component to be optimized independently - the stream manager for portability and the device drivers for performance.
2Ease of operation
If multiple content processes are managed using platform-specific device drivers without unified management, then individual process execution is possible, but resource management efficiency decreases and CPU utilization deteriorates
Solution Approach 1:
The patent merges the management of multiple content processes into a single stream manager that handles process creation, priority assignment, and resource allocation centrally. This unified management approach improves CPU resource utilization by optimizing the execution schedule of multiple processes simultaneously, rather than allowing each process to run independently with suboptimal resource usage.
Solution Approach 2:
The stream manager dynamically adjusts process priorities and resource allocation based on real-time system conditions and process requirements. This dynamic management allows the system to optimize CPU utilization by allocating resources to high-priority processes when needed and reducing allocation to lower-priority processes when system resources are constrained.
3Reliability
If platform-specific device drivers are used for content processing, then desired performance is achieved, but development processes increase due to platform dependence
Solution Approach 1:
The stream manager is designed as a universal, platform-independent component that provides consistent interfaces and functionality across different operating systems and hardware platforms. This universality reduces development complexity by allowing the core process management logic to be written once and ported to multiple platforms, while platform-specific device drivers handle the variations in underlying system behavior.
Data Source
AI summary
A method of configuring and performing stream data processing linked to a series of process points for high portability uses a link module to connect process points, called peer modules, to configure a stream data path. A single execution context is used for scheduling to enable high-performance processing. These constituent features are provided in a layer configuration to realize high portability and ease of development.
