Alternate Audio Source Synchronization via Embedded Tags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often encounter unsatisfactory audio portions in audio-visual content, such as offensive language or undesirable dialog, and desire alternative audio sources for enhanced viewing experiences, particularly during events like sporting events where different commentary is preferred.
Innovation Solution
The system identifies and retrieves alternate audio sources by embedding tags within video content, allowing users to query databases like Google or Yahoo for corresponding audio streams, and synchronizes these streams to ensure synchronized playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If alternate audio sources are retrieved from separate streams (Internet, radio broadcasts), then audio content variety and user choice are improved, but synchronization difficulty and system complexity increase
Solution Approach 1:
The patent uses content identifiers and timing metadata as intermediary elements to bridge the separate video and audio streams. These intermediaries enable the system to match and synchronize alternate audio sources from different sources (Internet, radio broadcasts) with the video content without requiring direct integration of the separate streams, thus managing complexity while maintaining versatility
2Adaptability or versatility
If video content and audio content are received as separate streams, then audio content flexibility and alternate source availability are improved, but synchronization precision deteriorates
Solution Approach 1:
The patent applies preliminary action by embedding content identifiers and timing metadata into the video content beforehand. This pre-prepared information allows the system to quickly and accurately synchronize alternate audio streams without requiring complex real-time analysis, thus maintaining synchronization precision while accepting stream separation for flexibility
3Adaptability or versatility
If multiple alternate audio sources are made available, then user satisfaction and content adaptability are improved, but information loss and retrieval difficulty increase
Solution Approach 1:
The patent uses content identifiers as a feedback mechanism that allows the system to verify and match alternate audio sources with the correct video content. This feedback loop ensures that even when multiple audio sources are available, the system can accurately identify and retrieve the appropriate audio stream, preventing information loss through systematic matching and verification

AI summary
Audio and video signals are synchronized for pleasing presentation of content. As content is streamed to a device, an audio portion may lag or lead a video portion. Spoken words, for example, are out of synch with the lip movements. Video content is thus synchronized to audio content to ensure streaming content is pleasing.
