Video Playback System Resource Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video players face issues with smooth playback due to independent modules that do not interact, leading to resource allocation imbalances and pauses when resolution, code rate, or coding manner changes.
Innovation Solution
A video information play system comprising a video file separator, information processing unit, system resource monitoring module, decoding parameter setting unit, and adaptation unit that processes and configures parameters to optimize resource usage and ensure smooth playback by adjusting decoding and video play parameters based on hardware and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If modules in a play system are independent and only transmission of video stream data occurs, then device complexity is reduced and ease of manufacture is improved, but resource allocation becomes unbalanced and playback smoothness deteriorates
Solution Approach 1:
The patent merges independent modules into an integrated play system where the video file separator, information processing unit, decoding parameter setting unit, and adaptation unit work together as a coordinated whole. This allows resource allocation optimization and parameter adjustment across modules, ensuring smooth playback while maintaining manageable system complexity through functional integration.
Solution Approach 2:
The adaptation unit implements feedback mechanisms by monitoring video information parameters and dynamically adjusting decoding parameters and information processing unit configurations. This closed-loop control ensures that resource allocation is optimized in real-time based on actual playback requirements, preventing pauses and maintaining playback smoothness.
2Manufacturing precision
If resolution, code rate, and coding manner requirements increase, then video quality is improved, but system resource consumption increases and playback smoothness may deteriorate
Solution Approach 1:
The system dynamically adjusts decoding parameters and information processing unit configurations based on video information parameters such as resolution, code rate, and coding manner. The adaptation unit modifies system resource allocation in real-time to match the actual video quality requirements, ensuring high video quality when needed while optimizing resource consumption to prevent playback interruptions.
3Productivity
If all resources are allocated to a play module that most frequently makes requests, then that module's performance is improved, but other play modules experience pauses and overall system reliability deteriorates
Solution Approach 1:
The adaptation unit changes resource allocation parameters dynamically based on the specific requirements of different play modules and video information parameters. Instead of permanently allocating all resources to the most frequent requester, the system adjusts decoding parameters, buffer sizes, and processing priorities to balance resource distribution, ensuring all modules can operate smoothly without pauses.
