Synchronizing Audio and Metadata for Emergency Session Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NG9-1-1 systems lack the capability to integrate and synchronize the presentation of audio data and metadata, such as caller location, during a session, which is essential for reconstructing emergency communication scenarios effectively.
Innovation Solution
A system and method that receive audio and metadata packets, extract relevant metadata information, and store it in association with the audio data, allowing for the simultaneous replay of audio and visual representation of metadata, like caller location, enabling synchronized presentation and reconstruction of sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio data and metadata are handled separately in NG9-1-1 systems, then system simplicity is maintained, but the capability to integrate and synchronize presentation of audio and metadata is lost
Solution Approach 1:
The patent combines separate audio data handling and metadata handling into a unified session reconstruction system. The PSAP server integrates audio packets and metadata packets, synchronizes them based on timing information, and presents them together in a coordinated manner, enabling simultaneous replay of audio and visual metadata presentation.
Solution Approach 2:
The PSAP server is enhanced to perform multiple functions: receiving audio packets, receiving metadata packets, synchronizing these packets, and presenting both audio and visual metadata. This multi-functional approach allows a single system to handle both audio and metadata integration without requiring separate dedicated systems.
2Loss of information
If NG9-1-1 systems handle various types of information separately, then information integrity is maintained, but the ability to provide integrated presentation and reconstruction of sessions is unavailable
Solution Approach 1:
The system performs preliminary synchronization of audio packets and metadata packets before presentation. Timing information is extracted and used to pre-align the packets, ensuring that when playback occurs, the audio and metadata are presented simultaneously and accurately reflect the original session timing.
Solution Approach 2:
The PSAP server acts as an intermediary that receives separate audio and metadata packets, processes them through synchronization based on timing information, and outputs coordinated presentations. This intermediary function bridges the gap between separate information handling and integrated presentation.

AI summary
A system and method for reconstructing a session. A method may include receiving audio and metadata packets related to a session. Audio data may be recorded and metadata information may be extracted from the metadata packets and stored in association with the audio data. A session may be reconstructed by simultaneously replaying the audio data and presenting a visual representation of the metadata.
