Video Sequence Selection Using Multi-Source Subdividing Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing and subdividing video documents, particularly in sports, lack the ability to provide fine-grained selection of video sequences, relying on single subdividing means that do not adequately respond to user interests, especially in time-constrained or score-constrained sports.
Innovation Solution
A method involving the use of at least two different subdividing means to extract and select video sequences, allowing for entry of specific selection criteria and the generation of summaries by concatenating sequences, with options for chronological or criterion-defined ordering, and the ability to substitute or refine sequences based on satisfaction indices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single subdividing means is used to extract video sequences, then the analysis process is simple, but the selection precision and user interest matching are insufficient
Solution Approach 1:
The patent divides the video analysis process into multiple independent subdividing means (structure-based, index-based, event-based), each handling specific aspects of sequence extraction. This segmentation allows each means to specialize in particular types of sequences, improving selection precision without requiring a single complex system to handle all cases
Solution Approach 2:
The patent creates a universal selection framework that can accommodate multiple different subdividing means (structure analysis, index matching, event detection). This multi-functional approach allows the system to adapt to different user needs and video types by selecting appropriate subdividing means, improving precision while managing complexity through modular design
2Measurement precision
If multiple subdividing means are used to extract video sequences, then the selection precision improves, but the device complexity increases

3Measurement precision
If manual selection of sequences is required, then the user can ensure high quality selection, but the productivity and efficiency are reduced
Solution Approach 1:
The patent performs preliminary automatic analysis of video documents using multiple subdividing means to pre-identify and extract candidate sequences before user selection. This preliminary action reduces the manual workload by pre-processing the video content and organizing sequences according to different criteria (structure, indices, events), allowing users to refine rather than create selections from scratch
Solution Approach 2:
The system enables users to automatically generate summaries by selecting predefined criteria (structure-based, index-based, event-based) without requiring manual frame-by-frame analysis. The automated subdividing means perform the heavy lifting of sequence identification, and users can combine these automatically generated sequences to create summaries, significantly improving productivity while maintaining quality through criterion-based selection

AI summary
The invention relates to a method of selecting parts of an audiovisual document. First, the document is analyzed by at least two subdividing means in order to extract from it at least two groups of audiovisual sequences. Then, selection criteria associated with each of the two subdividing means are entered. Finally, a list of sequences responding to all the selection criteria entered previously is generated.According to a refinement, the sequences are concatenated in a chronological order in order to generate an audiovisual document representative of the audiovisual document.The invention also relates to a device for displaying the sequences selected according to the method.
