Solution Overview

Problem

Current video processing methods restrict target slice information to shots, limiting accuracy and flexibility in video segmentation.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If video slices are segmented based on shots, then the segmentation process is simple and easy to implement, but the target slice information is restricted to shots and accuracy is reduced

Engineering Contradiction:

Improveease of segmentationVSAvoidaccuracy of target slice information

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent segments the video into multiple video segments based on candidate slice information, then evaluates each segment to determine probability information. This segmentation allows the system to move beyond shot-based restrictions and achieve more accurate slice information by analyzing content within segments rather than being constrained by shot boundaries.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an evaluation model as an intermediary between the video segments and the target slice information determination. This evaluation model processes the video segments and generates probability information, which then guides the determination of target slice information. This intermediary mechanism enables accurate slice information to be determined without being restricted to shot boundaries.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If video slices are segmented based on shots, then the processing process is straightforward, but flexibility in determining target slice information is limited

Engineering Contradiction:

Improvesimplicity of processingVSAvoidflexibility of target slice information

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent makes the slice determination process dynamic by using an evaluation model that analyzes video segments and generates probability information. This dynamic approach allows the target slice information to be determined based on actual video content characteristics rather than fixed shot boundaries, providing flexibility while maintaining a relatively simple processing framework.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter used for slice determination from shot-based boundaries to probability-based determination. By using probability information generated from video segment evaluation, the system can adaptively determine target slice information that is not constrained by shot structure, thereby improving flexibility without significantly complicating the processing approach.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If shot-based segmentation is used, then the method is simple to implement, but the accuracy and precision of video processing is reduced

Engineering Contradiction:

Improvecomplexity of segmentation methodVSAvoidprecision of video processing

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent implements a feedback mechanism where the evaluation model processes video segments and generates probability information that feeds back into the target slice information determination. This feedback loop enables the system to continuously refine its slice determination based on actual video content, improving processing precision without substantially increasing implementation complexity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical shot-based segmentation approach with a content-based evaluation system. Instead of relying on fixed shot boundaries, the system uses an evaluation model to analyze video segments and determine target slice information based on content characteristics. This substitution improves processing precision while keeping the overall method relatively simple.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
