Audio Video Signal Processor Background File Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio/video systems do not effectively notify users if an inappropriate or damaged file is assigned to an immediate output switch, leading to issues with file reproduction.
Innovation Solution
An audio/video signal processor that displays a judgment result on a user interface, reproducing assigned files in the background without sound or image to check for normalcy, and periodically re-checking files for integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If file assignment is performed without verification, then assignment operation is simple and fast, but file normality cannot be confirmed leading to reproduction failures
Solution Approach 1:
The system performs preliminary verification of assigned files by reproducing them in the background before actual use. This advance checking ensures file normality is confirmed prior to reproduction operations, preventing playback failures without requiring complex user-side verification procedures
Solution Approach 2:
The system automatically verifies file normality through background reproduction operations without requiring user intervention. The processor autonomously checks assigned files and manages verification status, eliminating the need for complex manual verification processes while ensuring reliability
2Reliability
If background reproduction is performed for verification, then file normality can be confirmed, but system resources are consumed
Solution Approach 1:
The system performs partial verification by reproducing files in the background with sound output disabled. This approach verifies file normality sufficient for reliability purposes while avoiding the excessive resource consumption of full-quality playback, achieving the right balance between verification accuracy and energy efficiency

AI summary
An apparatus is provided in which a user can easily check that an appropriate audio file is assigned. A system includes a PC connected to a communication line, and an audio interface apparatus that has an immediate output switch that outputs, to the PC, a reproduction start instruction signal of an audio file which is assigned in advance in response to a user operation. The PC judges, when an audio file or a video file is assigned by a user operation and in the background, whether or not the assignment is normal, and displays a judgment result in association with a virtual switch displayed on the display corresponding to the immediate output switch. The judgment is also repeatedly executed in the background at a predetermined timing after the assignment, and when the assignment is not normal, this is displayed.
