Vehicle Media Audio Matching for Synchronized Ad Visuals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-based media systems often lack the ability to provide additional or alternative visual information for advertisements received via radio broadcasts, as these broadcasts may not encode such information, limiting occupant engagement and advertiser opportunities.
Innovation Solution
A vehicle-based media system that captures audio content, identifies reference audio content with a threshold similarity to the captured content, and retrieves associated visual content, such as QR codes, to enhance the occupant's experience and increase interaction with advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If radio broadcasts do not encode visual information, then the system cannot retrieve visual content, but this limits occupant engagement and advertiser opportunities
Solution Approach 1:
The system uses an intermediary process of audio capture and identification to bridge the gap between audio-only radio broadcasts and visual content delivery. The microphone captures audio content, which is then identified and used as a key to retrieve associated visual content from external sources, effectively mediating between the limited radio broadcast and the desired visual enhancement
Solution Approach 2:
The system performs preliminary action by capturing and identifying audio content before visual content is needed. By pre-processing the audio signal and identifying reference audio content, the system prepares the necessary information in advance to efficiently retrieve and display the corresponding visual content when required
2Adaptability or versatility
If the system captures and processes audio content to identify visual content, then occupant engagement increases, but system complexity increases
Solution Approach 1:
The system applies multi-functionality by using the microphone and audio processing capabilities for multiple purposes: capturing audio content from speakers, identifying reference audio content, and triggering visual content retrieval. This universal approach allows a single audio processing chain to serve multiple functions, reducing the need for separate dedicated systems
Solution Approach 2:
The system performs self-service by using its own audio output and microphone to capture and identify the audio content it is already playing. This self-referential approach allows the system to autonomously identify when to display visual content without requiring external input or manual control, reducing operational complexity
3Adaptability or versatility
If the system displays visual content for advertisements, then advertiser opportunities increase, but information processing requirements increase
Solution Approach 1:
The system extracts only the necessary audio features from the captured audio content to identify reference audio content and retrieve visual content. By extracting only the essential identifying characteristics rather than processing the entire audio signal in detail, the system reduces information processing requirements while still achieving accurate visual content matching

AI summary
In one aspect, an example method to be performed by a vehicle-based media system includes (a) receiving audio content; (b) causing one or more speakers to output the received audio content; (c) using a microphone of the vehicle-based media system to capture the output audio content; (d) identifying reference audio content that has at least a threshold extent of similarity with the captured audio content; (e) identifying visual content based at least on the identified reference audio content; and (f) outputting, via a user interface of the vehicle-based media system, the identified visual content.
