Video Snapshot Header Generation Under Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating a copy of a video under recording results in duplicate content occupying storage space and reduces efficiency due to the time-consuming copy procedure, affecting video playback and editing.
Innovation Solution
A method and system that generate a snapshot header file by replacing the unique material identifier in the original video file's header information with a different identifier, allowing access to the video content without copying the entire file, thus reducing storage space usage and maintaining efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a copy of the video under recording is made available to users, then users can start playing or editing videos before completing recording, but storage space is occupied by duplicate content
Solution Approach 1:
The patent creates a snapshot copy of the video file header containing metadata and indexing information, rather than copying the entire video content. This header copy enables video playback and editing operations while occupying minimal storage space, resolving the contradiction between accessibility and storage consumption.
2Ease of operation
If a copy procedure is performed to make video available for playback and editing, then users can access video content early, but the copy procedure is time consuming and reduces efficiency
Solution Approach 1:
The patent extracts only the essential header information (metadata, indexing data, file structure) from the video file to create a snapshot copy. This extraction approach allows rapid creation of accessible video copies without the time-consuming process of duplicating entire video content, thereby reducing copy procedure time while maintaining playback and editing functionality.
3Reliability
If the entire video file is copied for user access, then complete video content is available for playback and editing, but storage space is heavily occupied and processing efficiency decreases
Solution Approach 1:
The patent segments the video file into header information (metadata, indexing) and content data, then creates a snapshot copy containing only the header segment. This segmentation allows the system to maintain complete video content availability for reliable playback and editing while using minimal storage space and improving processing efficiency by working with the smaller header copy rather than duplicating entire video files.

AI summary
A method and system for generating snapshot of video under recording, wherein the method comprises retrieving a header information of the original video file as a first header information when a read instruction requesting the original video file under recording is received; replacing a first unique material identifier (UMID) stored in the first header information with a second UMID to form a second header information; storing the second header information as a header information of a snapshot header file; and generating a snapshot video file and providing the snapshot video file to a client when the snapshot header file is requested by the client, wherein a header information of the snapshot video file is generated in accordance with the second header information, and a snapshot content of the snapshot video file is generated by retrieving a part of the original video file defined by the snapshot header file.
