Temporal Media Correlation for Incident Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety event-related communications media, which include subject matter and discussion media, are typically logged and displayed linearly by time of capture, making it impossible to associate discussion media with relevant subject matter media during incident review.
Innovation Solution
A communication system that correlates media content based on temporal proximity, associating subject matter media with related discussion media by determining time offsets and storing them together in a media storage system, allowing for event or incident reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media content is logged and displayed linearly by time of capture, then the logging process is simple and systematic, but it becomes impossible to associate discussion media with relevant subject matter media during incident review
Solution Approach 1:
The patent introduces a new temporal dimension (time of access/time of conveyance) in addition to the original time of capture dimension. This creates a multi-dimensional media organization system where media can be associated not only by when it was captured but also by when it was accessed or discussed, enabling proper association of discussion media with subject matter media while maintaining systematic logging
Solution Approach 2:
The system introduces time offset analysis as an intermediary mechanism to bridge subject matter media and discussion media. By calculating and comparing time offsets between media capture times and access/conveyance times, the system mediates the association between different media types without requiring a complete restructuring of the logging process
2Stability of the object's composition
If media is arranged according to time of capture in a linear fashion, then the media organization is straightforward and systematic, but discussion media cannot be associated with the relevant subject matter media under discussion
Solution Approach 1:
The patent segments the temporal relationship into distinct components: time of capture, time of access, time of conveyance, and time offset. This segmentation allows the system to maintain the stable linear organization by time of capture while simultaneously creating contextual associations through separate time offset calculations, preventing loss of contextual information
Solution Approach 2:
By adding the dimension of time offset (difference between capture time and access/conveyance time) to the existing time of capture dimension, the system enables contextual association of discussion media with subject matter media while preserving the stable linear organization structure for logging and storage
3Productivity
If all media intents are logged by time of capture only, then the logging system remains simple and efficient, but it fails to support proper incident review where discussion media needs to be linked to subject matter media
Solution Approach 1:
The system performs preliminary time offset calculations and stores time of access and time of conveyance data during the logging phase, rather than requiring complex real-time analysis during incident review. This preliminary action maintains logging efficiency while ensuring that all necessary temporal data is available for accurate incident review and media association
Solution Approach 2:
The patent uses time offset as an intermediary metric that can be calculated and stored during efficient logging operations, then used during incident review to accurately associate discussion media with subject matter media. This intermediary approach maintains both logging efficiency and review accuracy by decoupling the logging process from the complex association analysis

AI summary
A communication system is provided that analyzes event-related media by correlating various media content based on the media being time-wise proximate to each other. Thereby, the communication system provides an informational tool for law enforcement agencies to correlate different media that all relate to a same event, such as subject matter media with related discussion media. For example, the subject matter media may comprise video, video stills, biometrics, sensor data, Automatic Vehicle Location (AVL) data, pictures, BOLO (Be On the LookOut) bulletins, and the like, while the related discussion media may comprise Push-to-Talk talkbursts, telephone conversations, Instant Messaging (IM), emails, and other forms of discussion media. By correlating such media, the communication system facilitates event or incident reconstruction by providing related media together when providing event or incident playback.
