Solution Overview
Problem
Existing video processing systems face difficulties in efficiently managing video playback speed, making it hard for users to identify and understand objects of interest in video data due to varying complexity levels across different segments.
Innovation Solution
A video processing system that identifies objects of interest in video data and adjusts playback speeds based on complexity ratings, allowing for different segments to be played at varying speeds to enhance user understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video data is increased for surveillance operations, then coverage and monitoring capability are improved, but difficulty in identifying objects of interest and processing video information increases
Solution Approach 1:
The patent segments video data into multiple clips based on detected events or changes in scenes. Each clip represents a distinct segment with specific objects or actions, making it easier for users to navigate and identify objects of interest without reviewing the entire large volume of video data.
Solution Approach 2:
The patent introduces an intermediary processing system that automatically analyzes video data, detects events, generates clips, and creates a structured representation. This intermediary layer between raw video data and user interaction simplifies the complexity of identifying objects of interest in large video datasets.
2Ease of operation
If uniform playback speed is used for all video segments, then processing simplicity is maintained, but user understanding and analysis efficiency decrease for complex segments
Solution Approach 1:
The patent implements dynamic playback speeds that automatically adjust based on the complexity and content of each video clip. Simpler segments are played back faster, while complex segments with important objects or events are played back slower or paused, optimizing user analysis efficiency without requiring manual intervention.
Solution Approach 2:
The patent changes the playback speed parameter dynamically based on video content analysis. The system evaluates each clip's complexity and automatically adjusts the playback speed parameter to match user comprehension needs, improving analysis efficiency while maintaining operational simplicity.
3Loss of information
If all video segments are reviewed in detail, then complete understanding is achieved, but time consumption increases significantly
Solution Approach 1:
The patent applies partial review action by allowing users to quickly scan through less important video segments at higher speeds while automatically slowing down or pausing only the critical segments that require detailed examination. This selective approach maintains complete understanding while significantly reducing overall time consumption.
Solution Approach 2:
The patent implements periodic playback with varying speeds - fast playback for routine segments, slow playback for critical segments, and pauses for complex segments requiring detailed analysis. This periodic variation in playback speed optimizes both understanding completeness and time efficiency.
Data Source
AI summary
Systems, methods, and software described herein manage the playback speed of video data based on processing objects in the video data. In one example, a video processing service obtains video data from a video source and identifies objects of interest in the video data. The video processing service further determines complexity in frames of the video data related to the objects of interest and updates playback speeds for segments of the video data based on the complexity of the frames.
