Solution Overview

Problem

Users face difficulties in editing video files recorded by multiple cameras on intelligent terminals after multi-scene video recording is completed.

Innovation Solution

A method and apparatus for multi-scene video recording that generates a description file during the recording process, allowing video files from multiple cameras to be separately stored and simultaneously played, edited, or shared on a single interface based on the description file.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras record videos separately, then video recording capability is improved, but video file processing complexity increases

Engineering Contradiction:
Improvevideo recording capabilityVSAvoidvideo file processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a description file as an intermediary data structure that mediates between multiple separately recorded video files. This description file contains metadata about each video file including file paths, timestamps, and camera parameters, allowing the system to manage multiple video files through a unified interface without increasing processing complexity. The description file acts as a central index that simplifies access and manipulation of multiple video files.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a universal processing interface that can handle multiple video files from different cameras simultaneously. The same interface used for single-camera video processing is extended to support multi-camera recordings through the description file, allowing play, edit, and share operations to work uniformly across all recorded videos without requiring separate processing logic for each camera.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If video files from multiple cameras are separately stored, then storage organization is improved, but user operation convenience deteriorates

Engineering Contradiction:
Improvestorage organizationVSAvoiduser operation convenience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The system performs preliminary organization of video files by creating the description file during the recording process itself. This description file pre-organizes all video file information including paths, timestamps, and camera identifiers, so that when users need to access or process the videos, the work of organization has already been completed. This eliminates the need for users to manually manage multiple video files after recording.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The description file serves as an intermediary layer between the separately stored video files and the user interface. Instead of requiring users to directly manage multiple video files, the system provides a unified interface that operates on the description file, which in turn manages all video files. This intermediary approach maintains storage organization while significantly improving user operation convenience.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If a description file is generated to manage multiple video files, then video processing efficiency is improved, but data management complexity increases

Engineering Contradiction:
Improvevideo processing efficiencyVSAvoiddata management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the data management system into two distinct components: the description file containing metadata and references, and the actual video files containing media data. This segmentation allows the system to process video files efficiently by working with the lightweight description file for coordination, while keeping the heavy video data separate. The description file is divided into structured fields (file paths, timestamps, camera parameters) that can be easily parsed and managed.

Inventive Principle:
Principle #1Segmentation

AI summary

This application provides a multi-scene video recording method and apparatus, and an electronic device. In the method, a description file may be generated in a multi-scene video recording process, and video files recorded by cameras may be separately stored. Further, the video files recorded by the cameras may be simultaneously played, edited, or shared on a same interface based on the description file, so that a user can perform, based on a requirement of the user, an operation on the video files generated by the multi-scene video recording, thereby improving convenience of video file processing.
