Audio Video Content Search Using Transcripts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional search methods for video and audio content are limited, as they primarily rely on program data and metadata, which may not adequately represent the actual content, failing to provide users with specific information they seek.
Innovation Solution
A system that analyzes video and audio content to identify spoken words, generates transcripts, and performs text searches to find matching keywords, providing time indicators for the location of matched words within the content, allowing users to play and highlight relevant sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional search methods rely on program data and metadata, then the search system is simple to operate, but the search accuracy and representativeness of actual content deteriorates
Solution Approach 1:
The patent introduces transcripts as an intermediary layer between the original audio/video content and the search system. These transcripts convert spoken content into searchable text, enabling accurate keyword-based searches without requiring users to analyze raw media files directly. This mediator approach maintains search simplicity while dramatically improving accuracy.
Solution Approach 2:
The patent replaces manual content analysis with automated speech-to-text conversion and computerized text searching. Instead of users manually reviewing video/audio content to find information, the system automatically generates transcripts and enables text-based search, substituting mechanical human analysis with automated computational processes.
2Loss of information
If the system analyzes spoken words to generate transcripts, then the representativeness of actual content improves, but the processing time and computational resources increase
Solution Approach 1:
The patent performs speech-to-text conversion and transcript generation in advance, before the actual search operation. By pre-processing the content into searchable text format, the system eliminates the need for real-time analysis during user searches, thus reducing perceived processing time while maintaining complete content representativeness.
Solution Approach 2:
The patent creates text copies (transcripts) of the original audio/video content. These transcripts are simplified representations that preserve the semantic information of the spoken content while being much faster to process and search. The system searches the text copy rather than the original media, significantly reducing processing time while maintaining information accuracy.
3Ease of operation
If the system provides time indicators for matched words, then the user can quickly locate specific content segments, but the complexity of result presentation increases
Solution Approach 1:
The patent introduces time indicators as an intermediary element that bridges the search results and the original content. These indicators act as navigation markers that guide users to specific locations in the media without requiring complex analysis or interpretation. The time indicator simplifies the user's task of locating content while adding minimal structural complexity to the system.

AI summary
Video and audio content is searchable using a text search. A search component can analyze respective items of content to identify words spoken in the items of content, and generate respective transcripts of the respective words of the items of content based on the analysis. The search component receives a text search comprising a keyword and analyzes the respective transcripts to determine whether a transcript(s) contains a word that matches or substantially matches the keyword. The search component generates a search result(s) associated with the transcript(s) that at least is a substantial match to the keyword. The search component can present a time indicator indicating a time position in proximity to where the word is located in the content of the search result(s), and presentation of the content can start from that time position. The search component can be executed in a set-top box associated with a presentation device.
