Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing technologies face challenges in efficiently managing resource constraints such as memory, processing speed, and encoding/decoding rates, which can negatively impact performance and coding efficiency, and adding resources may be costly and impractical.
Innovation Solution
Implementing a computing system that detects constrained resource contexts and employs a predefined bitstream to temporarily reduce resource requirements by performing a conversion step, thereby alleviating resource constraints during video processing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video processing is performed with standard resource allocation, then processing quality is maintained, but resource consumption (memory, processing speed, encoding/decoding rates) increases
Solution Approach 1:
The patent applies dynamics by making the bitstream configuration adaptable to real-time resource conditions. The system dynamically selects between different bitstream configurations (first configuration for unconstrained resources, second configuration for constrained resources) based on detected resource availability, allowing the video processing system to optimize its performance characteristics according to current operational constraints without sacrificing processing quality when resources are available.
Solution Approach 2:
The patent implements parameter changes by modifying bitstream parameters based on resource context. When constrained resource contexts are detected, the system changes parameters such as encoding/decoding rates and memory allocation in the bitstream configuration, transforming the processing approach to match available resources while maintaining acceptable video processing performance.
2Reliability
If additional resources (memory, processing power) are added to improve video processing performance, then processing quality improves, but cost increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple bitstream configurations that are prepared in advance for different resource scenarios. The system detects the current resource context and selects from pre-prepared configurations, avoiding the need for real-time resource allocation decisions and reducing the need for additional hardware resources to handle varying performance requirements.
Solution Approach 2:
The patent implements universality by creating a single video processing system that can operate effectively across multiple resource conditions. The bitstream configuration mechanism allows the same hardware to universally handle both constrained and unconstrained resource scenarios by switching between different processing configurations, eliminating the need for separate hardware systems for different performance levels.
3Ease of manufacture
If resource constraints are strictly enforced to reduce costs, then hardware requirements are reduced, but video processing efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts its operation based on detected resource constraints. When constrained resource contexts are detected, the bitstream configuration changes to optimize for the available resources, maintaining acceptable processing efficiency without requiring additional hardware. This dynamic adaptation allows the system to achieve good efficiency on cost-effective hardware configurations.
Solution Approach 2:
The patent changes processing parameters in the bitstream configuration to match resource constraints. By adjusting encoding/decoding rates, memory allocation, and other parameters based on available resources, the system maintains video processing efficiency even with limited hardware, avoiding the efficiency deterioration that would result from fixed, constraint-based configurations.
