Audio Diagnostics System for Real-Time Content Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media devices often output audio content that does not match the intended audio content associated with video content, leading to suboptimal audio experience.
Innovation Solution
An audio diagnostics system equipped with a microphone and processor that detects output audio, compares it with the intended audio characteristics, and performs remedial actions to ensure alignment, such as changing audio input channels to match user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the media device outputs audio content without verification, then the device complexity is reduced, but the audio content accuracy deteriorates
Solution Approach 1:
The system uses a microphone to capture output audio, processes it through audio fingerprinting to generate an audio signature, and compares this signature with the expected audio signature from metadata. This feedback loop enables automatic detection and correction of audio content mismatches without increasing physical device complexity.
Solution Approach 2:
The patent replaces physical verification mechanisms with digital audio fingerprinting and signature comparison. Instead of using complex hardware to verify audio content, the system uses signal processing algorithms to generate and compare audio signatures, reducing mechanical complexity while improving accuracy.
2Manufacturing precision
If the system performs audio verification and correction, then the audio content accuracy is improved, but the processing time increases
Solution Approach 1:
The system performs audio fingerprinting and signature generation in real-time as audio plays back, rather than waiting for complete playback. The microphone captures audio continuously, and the processor generates signatures on-the-fly, allowing early detection and correction without requiring full audio processing.
Solution Approach 2:
The system compares audio signatures at multiple points during playback and can trigger correction after detecting a single mismatch. This partial verification approach is sufficient to ensure accuracy without requiring exhaustive checking of the entire audio content.
3Manufacturing precision
If no audio verification is performed, then the processing power is reduced, but the audio content accuracy deteriorates
Solution Approach 1:
The system extracts only the essential audio signature features from the complete audio signal for comparison purposes. By processing only the fingerprinted audio characteristics rather than the entire audio content, the system reduces processing power requirements while maintaining verification accuracy.

AI summary
Media content systems and methods are operable to detect sound using one or more microphones during presentation of a media content event. The audio content output is changed by a remedial action that is performed if the audio content detected by the microphones does not correspond to the intended audio content of the presented media content event.
