Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image output methods in BMCs discard cache frames without considering image data features, leading to abrupt interface changes and poor user experience during network congestion.
Innovation Solution
An image output method that acquires the continuous change feature of a display interface, generates control information based on thresholds, and adjusts image data output and compression quality to manage network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cache frames are directly discarded without considering image data features during network congestion, then the processing procedure is simple and network congestion is relieved, but abrupt visual interface changes occur and user experience deteriorates
Solution Approach 1:
The patent applies local quality by differentiating image frame processing based on their characteristics. Frames are categorized into static, dynamic, and key frames, and each type is handled differently during congestion - static frames can be discarded more aggressively while key frames are preserved to maintain visual continuity and user experience
Solution Approach 2:
The patent changes the parameter of frame selection by introducing frame importance weights and types. Instead of uniformly discarding frames, the system adjusts which frames to transmit based on their temporal and visual importance, using parameters like frame type (key, static, dynamic) and congestion level to dynamically control output
2Quantity of substance
If cache frames are discarded during severe network congestion, then network bandwidth is reduced and congestion is relieved, but interface change information is lost and visual continuity is broken
Solution Approach 1:
The patent implements feedback by continuously monitoring network congestion status and adjusting frame transmission decisions in real-time. The system receives feedback about congestion levels from the network output end and dynamically adjusts which frames to discard or transmit, creating a closed-loop control system that balances bandwidth usage with information preservation
Solution Approach 2:
The patent applies preliminary action by pre-classifying and marking frames with importance indicators before transmission. Frames are labeled as key frames, static frames, or dynamic frames in advance, allowing the system to quickly make discard decisions during congestion without losing critical interface change information
3Reliability
If image compression quality is increased to maintain visual quality during congestion, then user experience is maintained, but more network bandwidth is consumed and congestion worsens
Solution Approach 1:
The patent applies partial action by selectively maintaining high quality only for important frames (key frames and dynamic frames showing interface changes) while using lower quality or discarding static frames. This partial quality maintenance approach preserves visual continuity where needed while reducing overall bandwidth consumption
