Video Processing Device HDMI AVI InfoFrame Flag Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video signal transmission technologies fail to effectively notify the reception side about performed halftone processes and do not adequately transmit additional information, leading to potential image quality deterioration due to redundant image processing across devices.
Innovation Solution
Incorporating flags within the HDMI standard's AVI InfoFrame to indicate the execution and level of image processes, allowing devices to selectively perform necessary image enhancements and prevent redundant processing, thereby maintaining high-definition image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image processes are performed at multiple devices, then image enhancement capabilities are improved, but image quality deteriorates due to redundant processing
Solution Approach 1:
The transmitting device performs image processes in advance and embeds processing status information (flags) in the video signal before transmission. This preliminary action allows the display device to recognize already-performed processes and avoid redundant processing, thereby maintaining image quality while preserving enhancement capabilities.
Solution Approach 2:
The system implements feedback by embedding processing status information (flags indicating halftone process, noise reduction, etc.) into the transmitted video signal. The display device receives this feedback and uses it to determine whether to perform additional image processes, creating a closed-loop control system that prevents quality deterioration from redundant processing.
2Productivity
If processing status information is transmitted, then redundant processing is prevented, but data transmission complexity increases
Solution Approach 1:
The processing status information (multiple flags for different image processes) is merged into a single data structure within the video signal transmission stream. This combining approach allows comprehensive processing status communication without requiring separate transmission channels, thereby maintaining processing efficiency while minimizing transmission complexity.
Solution Approach 2:
The video signal itself serves as an intermediary carrier that transports both image data and processing status information (flags) simultaneously. This intermediary approach allows efficient communication of processing states without requiring additional dedicated communication channels, thus improving productivity without significantly increasing system complexity.
