Solution Overview

Problem

Law enforcement media files, such as videos from body or vehicle cameras, often lack timestamp information, making it time-consuming to locate specific events within large datasets.

Innovation Solution

A media processing platform automatically identifies and indexes events within media content files using sensor and contextual data from recording devices, allowing for efficient navigation to relevant portions of the media.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If media content files are reviewed manually to locate specific events, then complete information can be obtained, but significant time is spent reviewing unrelated portions of the media

Engineering Contradiction:

Improvetime to locate specific eventsVSAvoidefficiency of evidence review

Core Design Contradiction:

Loss of timeVSProductivity

Solution Approach 1:

The system performs preliminary analysis of sensor data and media content to automatically identify and index events before they are needed for review. By pre-processing the data to extract temporal and contextual information, the system enables rapid access to specific events without requiring manual review of entire media files, thus resolving the time loss issue.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary indexing system that mediates between the raw media content and the user's search queries. This intermediary layer of indexed event information allows users to quickly navigate to relevant portions without reviewing the complete media, effectively reducing time loss while maintaining access to complete information.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If sensor data is processed to identify events automatically, then quick access to specific events is enabled, but the system complexity increases

Engineering Contradiction:

Improveease of locating eventsVSAvoidcomplexity of media processing platform

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system segments the complex media processing task into distinct functional modules: sensor data collection, event identification, indexing, and media navigation. By dividing the complex process into manageable segments, the system achieves ease of operation for users while organizing complexity into structured components that can be independently optimized.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements self-service functionality where the media processing platform automatically identifies and indexes events without requiring manual intervention. The automated event detection and indexing processes handle the complexity internally, presenting simple query interfaces to users, thus achieving ease of operation while managing system complexity through automation.

Inventive Principle:

Principle #25Self-service

AI summary

Described herein are techniques that may be used to automatically identify and index events within a media content file. Such techniques may comprise receiving, from at least one recording device, a media content, receiving sensor data determined to correspond to the media content, determine a context associated with the at least one recording device based on the sensor data, identifying, based on one or more data patterns detected within the sensor data and based on the contextual data, at least one event, generating an index corresponding to the identified event, and storing an indication of the generated index in association with the media content.
