Image Processing Apparatus Error Recovery via Display Data Rewriting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses with HDMI terminals face issues in automatically adapting to communication path failures, leading to reduced user convenience due to inability to automatically switch to alternative stream formats when errors occur.
Innovation Solution
An image processing apparatus with a connector, error detector, player, memory, transmitter, and rewriting module that stores and transmits displaying data formats, and upon detecting errors, deletes higher-priority data to automatically switch to lower-priority formats, ensuring continuous stream reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image processing apparatus uses fixed device specs to determine reproducible formats, then the device structure remains simple and stable, but the system cannot automatically adapt to communication path failures, reducing reliability and user convenience
Solution Approach 1:
The system pre-stores multiple displaying data formats (e.g., different resolutions, color depths, frequencies) in memory before actual use. When a communication error occurs, the rewriting module can immediately switch to a pre-stored alternative format without requiring complex real-time analysis or user intervention, thus maintaining reliability while keeping the adaptation mechanism relatively simple.
Solution Approach 2:
The system changes display parameters (resolving level, color depth, frequency) by selecting from pre-stored displaying data with different specifications. The rewriting module modifies which format parameters are active based on error detection results, enabling adaptation to communication path failures through parameter switching rather than structural complexity.
2Adaptability or versatility
If the apparatus stores and transmits multiple displaying data formats, then adaptability to communication errors improves, but the memory usage and data transmission load increase
Solution Approach 1:
The displaying data is segmented into multiple discrete format options (e.g., 1080p, 720p, 480p with different color depths and frequencies), each stored as a separate record. This segmentation allows the system to store only essential format variations rather than all possible combinations, reducing memory usage while maintaining adaptability through selective format switching.
3Ease of operation
If the rewriting module deletes higher-priority displaying data upon error detection, then automatic format switching is enabled, but potential loss of optimal display quality occurs
Solution Approach 1:
The system prepares multiple displaying data formats with different quality levels in advance, creating a buffer or cushion of alternative options. When errors occur, the rewriting module can switch to lower-priority formats that serve as pre-prepared cushions against communication failures, enabling automatic recovery while preserving optimal quality when conditions permit.

AI summary
According to one embodiment, an image processing apparatus includes, an error detector configured to make an error check of the stream received, a player configured to reproduce the stream, a memory configured to store a plurality of pieces of displaying data indicating formats of the streams that can be processed by the image processing apparatus, a transmitter configured to transmit the pieces of displaying data stored in the memory to the external device in response to a request from the external device, and a rewriting module configured to delete one piece of displaying data stored in the memory when an error is detected by the error detector.
