Multimedia Summary Reproduction via Metadata Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies cannot summarize multimedia content without a pre-existing movie-in-short (MIS) metadata, limiting the ability to reproduce summaries of multimedia files.
Innovation Solution
A method and apparatus that extract metadata to generate a list of key points in time, allowing for the reproduction of summaries even without an MIS, and enabling conversion between normal and summary reproduction modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If MIS metadata is pre-included in multimedia files, then summary reproduction function is available, but device complexity and manufacturing requirements increase
Solution Approach 1:
The patent introduces metadata as an intermediary element that bridges the gap between full content and summary reproduction. By extracting and processing metadata containing time information about key scenes, the system can generate MIS lists without requiring complex pre-manufactured summary structures, thus simplifying the overall system while maintaining functionality
Solution Approach 2:
The patent extracts essential time information from full content metadata to create condensed MIS lists. By taking out only the critical time points and scene information needed for summary reproduction, the system avoids the complexity of storing and processing entire content or pre-manufactured detailed summaries
2Ease of operation
If MIS is pre-manufactured like trailers, then summary function is provided, but adaptability to different content and user needs is reduced
Solution Approach 1:
The patent enables the system to automatically generate MIS lists by extracting metadata from content itself, rather than relying on pre-manufactured summaries. This self-service approach allows the system to adapt to different content types and user preferences dynamically, creating summaries tailored to each specific multimedia file without requiring manual intervention for each content piece
Solution Approach 2:
The patent implements dynamic MIS list generation that can adapt to different reproduction scenarios. The system can adjust the MIS list based on content characteristics, user preferences, and reproduction context, making the summary function versatile and adaptable rather than static and content-specific
3Loss of information
If entire content summary is reproduced, then comprehensive overview is provided, but reproduction time and user patience requirements increase
Solution Approach 1:
The patent segments the content summary into key time points and important scenes rather than reproducing the entire content continuously. By dividing the summary into discrete, manageable segments based on metadata-extracted time information, the system provides comprehensive coverage of content highlights while significantly reducing reproduction time compared to full content playback
Data Source
AI summary
Provided are a method and apparatus for generating a movie-in-short (MIS). The method includes extracting metadata, in which predetermined points of time of content are recorded, generating a list of at least one MIS by using storage addresses of the points of time or reproduction points of time, which are indicated by the extracted metadata, storing the list, and reproducing a summary by reproducing the content during a predetermined time based on a point of time indicated by at least one MIS of the stored list.
