Audio-Video Device Test System Script Update via Sensing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current test methods for audio-video devices struggle to simulate real-user operations effectively, as automation tests are limited to predefined scripts and cannot reproduce abnormal events accurately, while manual tests are non-repeatable and slow down product development.
Innovation Solution
A test system comprising an output control circuit, sensing circuit, and processor that generates test sequences, outputs control signals, detects sensible conditions, and updates test scripts by recording and reproducing abnormal events to expand test coverage automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automation tests are performed according to pre-defined test scripts, then testing speed is improved, but the ability to simulate real user operations and detect abnormal events deteriorates
Solution Approach 1:
The system captures actual user operations through the sensing circuit and feeds them back to update the test script. When abnormal events are detected during automated testing, the system records the corresponding test signals and sensible conditions, then uses this feedback to automatically expand and refine the test script, making it progressively more aligned with real user behavior patterns.
Solution Approach 2:
The test system automatically generates and updates its own test scripts without requiring manual intervention. The processor autonomously captures abnormal events, records relevant test signals, compares them with existing test instructions, and expands the test script to include new test cases, enabling the system to self-improve its testing capabilities over time.
2Reliability
If manual tests are performed with additional test steps, then the ability to simulate real user operations is improved, but repeatability and testing efficiency deteriorate
Solution Approach 1:
The system uses the sensing circuit to capture and copy actual user operations and abnormal events. These captured operations are stored as test signals in the storage medium, creating a reusable library of real user behaviors that can be automatically replayed and tested across multiple devices without manual intervention, ensuring both authenticity and repeatability.
Solution Approach 2:
The processor automatically processes captured user operations, converts them into standardized test instructions, and integrates them into the test script without requiring tester involvement. This automation eliminates the non-repeatable nature of manual testing while preserving the ability to simulate real user operations.
3Adaptability or versatility
If test scripts are manually updated with additional test steps, then test coverage is improved, but the time required for script maintenance and issue reproduction increases
Solution Approach 1:
The system performs automatic test script expansion by capturing abnormal events during testing, recording the associated test signals and sensible conditions, comparing them with existing test instructions, and automatically generating new test cases. This eliminates manual script maintenance and accelerates the incorporation of new test scenarios.
Solution Approach 2:
The test script is continuously updated and expanded throughout the testing process rather than being manually modified in discrete steps. The system maintains an ongoing cycle of testing, capturing abnormal events, and automatically expanding the test script, ensuring test coverage continuously improves without interrupting the testing workflow.

AI summary
A test system for audio-video device comprises an output control circuit, a sensing circuit, a storage medium and a processor. The sensing circuit detects the sensible conditions of the AVDUT (Audio-Video Device Under Test). The storage medium stores a test script and a verification data set related to the AVDUT, wherein the test script comprises a plurality of test instructions, and each of the test instructions comprises a plurality of test signals. The processor is configured to generate a test sequence related to the test instructions, and outputs a plurality of control signals to the AVDUT through the output control circuit according to the test sequence, and the processor determines whether an abnormal event occurs in the AVDUT according to said sensible conditions, when the abnormal event occurs, the processor determines whether to update the test script according to a comparison result.
