Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to efficiently test the interworking performance of multimedia devices without redefining component coordinates when the user interface changes, and they fail to easily identify the interworking state between multiple devices.
Innovation Solution
An apparatus and method utilizing a database log tracking device and a processor to monitor logs, detect predetermined events, and compare event execution information with reference information to determine the operation states of interconnected multimedia devices, without relying on coordinate definitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If coordinate definitions of UI components are redefined when UI changes, then testing accuracy is maintained, but testing efficiency deteriorates due to repeated manual redefinition work
Solution Approach 1:
The patent uses image recognition to automatically capture and copy UI component information from screenshots, replacing manual coordinate definition. The system captures UI screenshots, automatically identifies component positions and attributes through image processing, and stores this information for test execution, eliminating the need to manually redefine coordinates when UI changes occur.
2Loss of information
If manual monitoring of interworking states is performed, then detailed state analysis is possible, but time consumption increases significantly
Solution Approach 1:
The patent replaces manual monitoring with automated log analysis systems. The system automatically captures logs from multiple devices, parses event information using predefined patterns, correlates events across devices, and generates interworking state reports without human intervention, significantly reducing time consumption while maintaining accurate state identification.
3Measurement precision
If comprehensive log analysis is performed across multiple devices, then interworking state detection accuracy improves, but system complexity increases
Solution Approach 1:
The patent segments the log analysis process into distinct modules: log collection from individual devices, event pattern matching, event correlation across devices, and state determination. Each module handles a specific aspect of the analysis, making the overall complex system manageable through functional decomposition and allowing independent optimization of each segment.

AI summary
An apparatus for testing a multimedia device includes a database log tracking device that transmits a log of a first terminal and a processor that monitors the log to detect a predetermined event, obtains event execution information at a timing when the event occurs from the first terminal and a second terminal interworking with the first terminal in response to that the event is detected, and compares the event execution information with predetermined reference information to determine operation states of the first and second terminals.
