Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback systems face challenges in maintaining optimal video quality due to varying available resources, leading to potential stalling and hiccups, as they struggle to adapt to changing conditions without compromising quality or requiring excessive user intervention.
Innovation Solution
A method that automatically switches between predefined frame rate profiles based on detected video quality and resource availability, allowing for dynamic adjustment of video processing algorithms to ensure optimal quality without visible artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If frame rate conversion algorithms are used to adapt frame rate, then video playback can be maintained under varying resource conditions, but the algorithm requires significant processing resources that may not be available in real-time processing
Solution Approach 1:
The patent changes the parameter of frame rate dynamically based on available resources. Multiple frame rate profiles are defined, and the system switches between them depending on resource availability and quality requirements, allowing adaptation without consistently consuming high processing resources
Solution Approach 2:
The system makes the frame rate dynamic rather than fixed. It continuously monitors resource availability and quality metrics, adjusting the frame rate profile in real-time to match current system conditions, enabling the system to be both adaptable and resource-efficient
2Reliability
If processing quality is reduced to prevent stalling and hiccups, then video playback stability improves, but video quality becomes suboptimal
Solution Approach 1:
The system dynamically adjusts processing quality through frame rate profile switching. Instead of using fixed low quality settings, it monitors actual system conditions and quality metrics, raising or lowering the frame rate profile to achieve the highest possible quality while maintaining stability when resources are limited
Solution Approach 2:
The system implements feedback by detecting quality metrics and using this information to adjust frame rate profile selection. This closed-loop approach ensures that quality is optimized based on actual system performance rather than predetermined conservative settings
3Device complexity
If a fixed frame rate profile is used, then processing is simpler and more predictable, but the system cannot adapt to varying resource availability over time
Solution Approach 1:
The patent segments the frame rate into multiple discrete profiles rather than using a single fixed value or continuous adjustment. This segmentation maintains relative simplicity while enabling adaptation, as the system only needs to switch between predefined profiles rather than calculate optimal rates dynamically
Solution Approach 2:
The system uses parameter changes by switching between predefined frame rate profiles. This approach maintains simplicity through predefined options while achieving adaptability through profile switching based on resource conditions, avoiding the complexity of real-time optimization algorithms
