Solution Overview

Problem

Media clients dynamically modifying content streams may face challenges in abandoning content modifications when emergency alerts occur, as existing systems lack efficient mechanisms to detect and respond to such events in real-time.

Innovation Solution

A mechanism is introduced that detects emergency-alert audio tones in media streams, allowing media clients or associated entities to abandon dynamic content modifications and switch to presenting emergency alerts, utilizing audio tone detection and signaling to ensure timely and accurate presentation of emergency content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the media client dynamically modifies content streams (e.g., replacing ads or adding overlays), then content customization and engagement are improved, but the ability to respond to emergency alerts in real-time deteriorates

Engineering Contradiction:

Improvecontent customization capabilityVSAvoidemergency alert response reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary detection of emergency-alert audio tones in the media stream before dynamic content modification is applied. By detecting the emergency tone advance and aborting the content modification operation, the system ensures emergency alerts are presented without interruption or overlay, maintaining reliability while preserving content customization capabilities for non-emergency situations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the media stream for emergency-alert audio tones and uses this feedback to dynamically control content modification operations. When an emergency tone is detected, the system immediately terminates any ongoing or scheduled content modification, creating a feedback loop that prioritizes emergency alert delivery while allowing normal content customization when no emergency is present

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If the media client processes and presents content modifications at specific time points, then content synchronization is improved, but the detection and response time for emergency alerts deteriorates

Engineering Contradiction:

Improvecontent modification timing precisionVSAvoidemergency alert detection time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary detection of emergency-alert audio tones before the scheduled content modification time point is reached. By checking for emergency conditions in advance and aborting early, the system avoids the time loss that would occur if detection happened after the modification was already initiated, thus preserving both timing precision and rapid emergency response

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

When an emergency-alert audio tone is detected, the system immediately skips or aborts the scheduled content modification operation and rushes to present the emergency alert content. This skipping mechanism eliminates unnecessary processing steps and ensures the fastest possible response to emergency conditions while maintaining precise control over content presentation timing

Inventive Principle:

Principle #21Skipping (Rushing through)

AI summary

A method and system for controlling dynamic content modification such as dynamic advertisement insertion. An example method includes detecting presence of an emergency-alert audio tone in a media stream accessible to a media client, and responsively causing the media client to abandon a dynamic content modification, such as to forgo a planned dynamic content modification or to discontinue an in-progress dynamic content modification. This method could occur while the media client is processing a given media stream for presentation, and the method could include detecting presence of the emergency-alert audio tone in the given media stream or alternatively in another media stream accessible to the media client. And in the latter case, the method could further involve causing the media client to switch from processing the given media stream for presentation to instead processing the other media stream for presentation, which could facilitate presenting of an associated emergency alert.
