Media Synchronization Verification Using Digital Fingerprints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual verification of media content synchronization between video and audio streams is time-consuming, lacks consistency, and relies on human judgment, leading to potential errors due to factors like fatigue and mood, and requires real-time playback to accurately assess synchronization.
Innovation Solution
A method using processor-generated fingerprints and signatures for each segment of video and audio components, allowing for rapid comparison of synchronization between master and copy programs without altering the original content, enabling objective and consistent verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual verification process is used to verify synchronization between video and audio streams, then human judgment can assess synchronization quality, but the process becomes time-consuming and lacks consistency
Solution Approach 1:
The patent replaces the manual mechanical verification process (human viewing and listening) with an automated electronic system that extracts audio and video data, generates fingerprints, and compares synchronization objectively through computer processing, eliminating time-consuming human review while maintaining verification accuracy
Solution Approach 2:
The patent creates digital fingerprints (copies) of audio and video segments that can be stored and compared without requiring actual playback of the original content, allowing rapid verification through data comparison rather than time-consuming real-time review
2Adaptability or versatility
If manual verification process is used by multiple individuals, then human judgment can be applied, but consistency and objectivity are compromised due to factors like fatigue and mood
Solution Approach 1:
The patent replaces human judgment with an automated electronic system that consistently applies the same synchronization verification algorithm to all copies, eliminating variability caused by human factors such as fatigue, mood, and subjective interpretation while maintaining the ability to verify synchronization quality
Solution Approach 2:
The patent transforms the verification process from subjective human assessment to objective parameter-based comparison by generating and comparing audio and video fingerprints using specific technical parameters, ensuring consistent and repeatable verification results across different copies and operators
3Measurement precision
If real-time playback is used for verification, then accurate synchronization assessment can be made, but the process requires significant time for each copy
Solution Approach 1:
The patent creates digital fingerprints (copies) of audio and video segments that capture the essential synchronization information without requiring actual playback, allowing rapid verification through data comparison that maintains accuracy while dramatically increasing throughput
Solution Approach 2:
The patent extracts only the essential synchronization-relevant data from the full media content to create compact fingerprints, separating the verification function from the complete content playback requirement, thereby enabling fast comparison while preserving synchronization assessment accuracy

AI summary
In a system and method for verification of media content synchronization, the system may include a processor configured to perform a method including determining at least one similarity score of a copy of a master program based on a comparison of at least one signature of the copy with at least one signature of the master program.
