Video Surveillance Key Moment Marking for Investigation Review

Solution Overview

Problem

Current video surveillance systems lack a mechanism to identify key moments in exported video data streams, requiring operators to spend excessive time understanding the content, as the streams are not self-explanatory, leading to inefficient review processes for investigations and evidentiary purposes.

Innovation Solution

The system allows for the creation, display, and playback of self-explanatory video data streams by marking key moments within the video data stream, enabling multiple playback sessions that correspond to these marked points, allowing operators to quickly understand incidents and export a single video clip with marked key frames, which can be played from different starting times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If operators manually review exported video data streams without key moment markers, then they can see the complete video content, but they spend excessive time trying to understand and locate key incidents

Engineering Contradiction:

Improvetime spent reviewing videoVSAvoidunderstanding of key moments

Core Design Contradiction:

Loss of timeVSLoss of information

Solution Approach 1:

The system performs preliminary action by automatically detecting and marking key moments in the video data stream before export. Key moment indicators are embedded in the video file during the export process, allowing operators to quickly locate and understand important incidents without manual review of the entire video.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces key moment indicators as an intermediary element between the video content and the operator. These indicators serve as visual markers that guide operators to important incidents, acting as a mediator that bridges the gap between raw video data and meaningful information extraction.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If operators export video data streams without key moment markers, then the export process is simple, but the video streams are not self-explanatory and require additional manual explanation

Engineering Contradiction:

Improveease of video reviewVSAvoidcontextual understanding

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary action by automatically detecting and marking key moments in the video data stream before export. Key moment indicators are embedded in the video file during the export process, allowing operators to quickly locate and understand important incidents without manual review of the entire video.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by making the video data stream self-explanatory through embedded key moment indicators. The video file contains its own navigation and explanation markers, allowing it to serve itself without requiring external manual annotation or explanation from operators.

Inventive Principle:

Principle #25Self-service

3Loss of information

If operators pause, reverse, and re-play video segments to understand key moments, then they can achieve better understanding, but the review process becomes time-consuming and inefficient

Engineering Contradiction:

Improvecomprehension of incidentsVSAvoidinvestigation efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The system performs preliminary action by automatically detecting and marking key moments in the video data stream before export. Key moment indicators are embedded in the video file during the export process, allowing operators to quickly locate and understand important incidents without manual review of the entire video.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical manual process of pausing, reversing, and re-playing video segments with an automated key moment detection and marking system. The electronic markers automatically guide operators to important incidents, substituting manual mechanical operations with automated electronic navigation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems and methods to create, display, and play self-explanatory video data streams for use in video surveillance are provided. Methods include displaying and playing an incident video data stream in a primary video panel on a viewing screen, and displaying and playing at least one playback session of the incident video data stream in at least one secondary video panel on the viewing screen. The at least one playback session corresponds to at least one marked key moment in the incident video data stream, and the at least one playback session is played in the at least one secondary video panel at a time corresponding to when the at least one marked key moment in the incident video data stream is being playing in the primary video panel.
