Video Processing Apparatus Segmentation for Storage Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video recording systems in vehicles occupy large storage space due to the need for continuous writing of index data during video recording, leading to inefficiencies in storage capacity and potential index space waste.
Innovation Solution
A video processing method that converts video streams into independently encoded or decoded data packets, which are then synthesized into video clips within a reporting cycle, eliminating the need for index writing during recording and optimizing storage space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If index data is continuously written into memory during video recording, then video fault recovery capability is provided, but storage space occupied by video recording becomes relatively large
Solution Approach 1:
The patent segments the video recording process into independent video clips, where each clip is self-contained and can be independently decoded. This eliminates the need for continuous index writing across the entire video stream, as each clip maintains its own integrity and can be recovered independently if a fault occurs.
Solution Approach 2:
The patent performs preliminary encoding and packaging of video data into complete, self-contained clips before storage. Each video clip is prepared in advance with all necessary decoding information embedded within it, so that when stored, no additional index data needs to be written during the recording process.
2Productivity
If index space is pre-calculated and pre-written based on resolution and frame rate, then video recording can proceed continuously, but index space waste is caused due to mismatch with actual index space and location
Solution Approach 1:
By dividing video recording into segmented clips, the patent eliminates the need for pre-calculating and pre-writing index data for the entire video stream. Each clip is independently structured with its own embedded timing and positioning information, removing the source of index space waste while maintaining continuous recording capability.
Solution Approach 2:
The patent embeds complete video clip information including timing and positioning data directly within each video clip file itself, creating a self-contained copy that does not require external index structures. This eliminates the mismatch between pre-calculated index space and actual usage.
Data Source
AI summary
A video processing method includes: receiving a video stream from a camera component; converting the video stream into at least one first data packet, where the at least one first data packet is independently encoded or decoded; and storing a first data packet obtained in a first reporting cycle as a first video clip.
