Emergency Alert Detection via Audio-Video Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency alert message systems on electronic devices, such as televisions, often result in abrupt channel switches that disrupt the viewer's experience, especially when the alert is not relevant or when the device is rendering non-broadcast content, leading to missed alerts due to lack of tuning to broadcast channels.
Innovation Solution
An electronic device and method for detecting emergency alert messages based on audio-video information, which automatically identifies relevant alerts by recognizing geo-location-specific objects and audio cues within media content, allowing for seamless extraction and output of emergency alerts even during non-broadcast content consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the service provider device switches the broadcasted signal to the emergency alert message upon detection, then the emergency alert message is delivered to the electronic device, but the viewer experience is abruptly disrupted and unnecessary switches occur when the alert is not relevant
Solution Approach 1:
The electronic device performs preliminary detection of emergency alert messages in received broadcast content before the service provider device switches channels. By detecting alert indicators (such as specific audio tones, visual markers, or data signals) in advance, the device prepares to display the alert seamlessly when it occurs, avoiding abrupt channel switches while ensuring reliable alert delivery.
Solution Approach 2:
The electronic device acts as an intermediary between the broadcast signal and the display output. It intercepts and analyzes the broadcast content locally, detecting emergency alert indicators and extracting alert messages independently. This intermediary function allows the device to control alert presentation without disrupting the main broadcast channel, thus maintaining viewer experience while ensuring alert reliability.
2Adaptability or versatility
If the electronic device is tuned to non-broadcast content (stored or streaming), then the viewer can consume non-broadcast content, but the emergency alert message cannot be delivered as the device is not receiving broadcast channels
Solution Approach 1:
The electronic device implements multi-functionality by simultaneously handling both broadcast content reception and non-broadcast content playback. While playing local or streaming content, the device continues to receive and analyze broadcast signals in parallel, detecting emergency alert indicators across all broadcast channels. This universal capability ensures alert message delivery reliability regardless of what content the viewer is currently consuming.
Solution Approach 2:
The broadcast signal reception and analysis operation continues uninterrupted while the device plays non-broadcast content. The electronic device maintains continuous monitoring of broadcast channels for alert indicators, ensuring that emergency alert detection is an ongoing process that does not pause or stop when switching to local or streaming content, thus preserving alert delivery reliability.
3Reliability
If the service provider device switches to broadcast the emergency alert message, then the alert is communicated, but the switch is abrupt and may be unnecessary when the alert is not relevant to the viewer
Solution Approach 1:
The electronic device performs preliminary detection and analysis of broadcast content to identify emergency alert indicators before the actual alert message is transmitted. By detecting these indicators in advance, the device can prepare to display the alert seamlessly, reducing the perceived disruption time for viewers while ensuring that only relevant alerts are presented.
Solution Approach 2:
The system implements feedback mechanisms where the electronic device continuously monitors broadcast content for alert indicators and adjusts its alert presentation based on detected relevance. The device analyzes contextual information from the broadcast signal to determine whether an alert is relevant to the current viewing context, providing feedback control over alert display to avoid unnecessary interruptions.
Data Source
AI summary
An electronic device and method for emergency alert message detection based on audio-video information is disclosed. The electronic device receives first media content received over a first broadcast channel. The electronic device renders second media content, which is different from the first media content. The electronic device further detects, from the received first media content, a set of objects associated with a geo-location corresponding to the electronic device. The set of objects corresponds to an emergency at the geo-location. The electronic device further detects an emergency alert audio in the received first media content. The electronic device further extracts an emergency alert message received over a second broadcast channel associated with the geo-location based on the detected set of objects and the emergency alert audio in the received first media content. The electronic device further renders an emergency alert signal associated with the emergency alert message.
