Dynamic Video Segment Selection via Object Recognition

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional video playback methods often present entire videos, leading to viewer disinterest due to uninteresting or irrelevant content at the beginning, which reduces the overall user experience.

Innovation Solution

A computer-implemented method and system that identifies a set of video segments, selects a subset based on object recognition and audience information, and generates a playback sequence to provide selected video segments without creating a new video file or performing additional video coding, allowing for dynamic and audience-specific playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the entire video is played back, then the complete content is presented, but viewer interest is lost due to uninteresting or irrelevant content

Engineering Contradiction:

Improvecontent completenessVSAvoidviewer engagement

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The video is divided into multiple segments, and only the most relevant segments are selected for playback based on object recognition analysis. This segmentation allows the system to present complete important content while excluding uninteresting portions, resolving the contradiction between content completeness and viewer engagement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different segments of the video are treated differently based on their content quality. The system identifies and prioritizes high-quality segments containing important objects or events, while low-quality segments are excluded. This local quality differentiation maintains essential information while improving overall viewer engagement.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If video segments are selected and played back in a customized sequence, then viewer engagement is improved, but additional processing and resource usage increase

Engineering Contradiction:

Improveviewer engagementVSAvoidprocessing resources

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system performs object recognition and segment selection in advance, before playback. By pre-analyzing the video content and identifying important segments upfront, the system avoids real-time processing during playback, thereby reducing resource usage during the actual viewing experience while still achieving improved viewer engagement.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If a subset of video segments is played back, then playback length is reduced, but some video content is omitted

Engineering Contradiction:

Improveplayback lengthVSAvoidvideo content

Core Design Contradiction:

Loss of timeVSLoss of information

Solution Approach 1:

The system extracts and removes uninteresting or irrelevant segments from the video, keeping only the essential content. By taking out the non-essential portions, the system reduces playback time significantly while preserving the core video content that viewers actually care about, thus resolving the contradiction between playback length and content completeness.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Systems, methods, and non-transitory computer-readable media can identify a set of video segments that represents a video. A subset of video segments can be selected out of the set of video segments. A list that indicates a playback sequence for the subset of video segments can be generated. Playback of the subset of video segments can be provided based on the playback sequence indicated via the list.
