Video Highlight Image Extraction for Low-Bandwidth Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content delivery systems lack efficient methods for extracting and presenting highlight sections from videos, leading to decreased user engagement and inefficient data transmission, especially in low-specification network environments.
Innovation Solution
A method and system that allow users to select and register partial video sections as comments, which are then used to extract highlight images based on user feedback and playback accumulation information, enabling preview and seamless content switching without full image downloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full video content is transmitted for preview, then content verification quality is improved, but data transmission volume increases and network burden increases
Solution Approach 1:
The patent extracts only the highlight sections and key frames from the full video content to create a condensed preview. Instead of transmitting the complete video, the system extracts and transmits only the essential visual and audio segments that represent the content's key moments, thereby reducing data volume while maintaining preview quality.
Solution Approach 2:
The patent divides the full video content into multiple highlight sections and key frames. The video is segmented into discrete, meaningful portions that can be independently transmitted and displayed. This segmentation allows the preview to convey content essence without requiring the entire video stream.
2Ease of operation
If traditional list-based selection process is used, then content organization is simplified, but user engagement decreases and verification time increases
Solution Approach 1:
The patent performs preliminary extraction and preparation of highlight sections and key frames before the user needs to verify content. The system proactively generates and stores these condensed previews, so when a user selects content, the verification can begin immediately without waiting for full video loading or sequential list browsing.
Solution Approach 2:
The patent enables continuous content verification through seamless playback of highlight sections. Instead of discrete list items requiring sequential selection, the highlight preview plays continuously, allowing users to engage with content flow uninterrupted. The system maintains continuous transmission and display of condensed content, eliminating verification gaps.
3Quantity of substance
If highlight image extraction is implemented, then data transmission is reduced, but system complexity increases
Solution Approach 1:
The patent implements self-service content verification where the client device autonomously extracts, processes, and displays highlight sections without requiring complex server-side processing for each individual request. The system uses locally stored video data and embedded metadata to automatically generate and transmit appropriate highlight previews, reducing server complexity while maintaining data efficiency.
Data Source
AI summary
Provided are a method, system, apparatus, and non-transitory computer-readable medium for extracting a highlight image of video content. A method configured as a computer includes providing video content to a client electronic device; receiving a selection on a partial section of the video content from the client electronic device; storing the selected partial section in association with the video content; and providing the stored partial section in a form of a comment on the video content.
