Broadcast Audio Data Embedding for Real-Time Listener Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AM/FM radio systems lack interaction between listeners and broadcasters, relying on passive listening experiences and inaccurate listener interest surveys, which can be misleading due to sampling issues and lack of real-time feedback.
Innovation Solution
An interactive audio system that embeds data within broadcast audio signals, allowing listeners to interact with broadcasters using embedded data decoded from the audio signals, enabling real-time feedback and direct communication through existing communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional AM/FM radio broadcasting is used, then listeners can receive audio content, but there is no interaction between listeners and broadcasters
Solution Approach 1:
The patent combines traditional AM/FM radio broadcasting with data transmission capabilities by embedding data within the audio signal itself. This merging allows the same broadcast channel to carry both audio content and interactive data, enabling listener-broadcaster communication without requiring separate communication infrastructure.
Solution Approach 2:
The broadcast system is enhanced to perform multiple functions: traditional audio broadcasting, data embedding, and interactive communication. The same radio frequency carrier signal serves both as an audio carrier and a data transmission medium, making the system universal and multi-functional.
2Measurement precision
If listener interest surveys are conducted by third parties, then listener preferences can be measured, but the data can be misleading due to sampling issues
Solution Approach 1:
Listeners actively participate in measuring their own preferences by using embedded data to search for, purchase, and engage with content they interest them in. This self-service approach generates accurate, real-time preference data directly from listener behavior rather than relying on third-party surveys.
Solution Approach 2:
The system establishes a feedback loop where listener interactions with embedded data (searches, purchases, engagements) are tracked and reported back to broadcasters in real-time. This continuous feedback provides accurate measurement of listener interests and program effectiveness.
3Speed
If listeners call radio stations to register interest, then some interaction is possible, but it is not real-time and lacks scalability
Solution Approach 1:
The manual process of calling radio stations is replaced with an automated electronic system. Listeners use mobile devices to interact with embedded data, search for content, and make purchases electronically, eliminating the need for phone calls and enabling simultaneous interactions from multiple listeners.
Solution Approach 2:
All interaction mechanisms (search capabilities, purchase options, contact information) are pre-configured within the embedded data before broadcast. Listeners can immediately act on their interests without delays, enabling real-time interaction rather than post-broadcast feedback.
4Adaptability or versatility
If data is embedded within audio signals, then real-time interaction is enabled, but the system complexity increases
Solution Approach 1:
Data embedding and audio broadcasting are merged into a single process. The same modulator that encodes audio signals also embeds data within the audio frequency spectrum, eliminating the need for separate data transmission infrastructure and reducing overall system complexity despite added functionality.

AI summary
Disclosed here is an interactive audio system and a method of operating the same. In one embodiment, the interactive audio system comprises a processor and a receiving module for receiving a radio frequency (RF) carrier signal associated with a broadcast station. The audio system further comprises a memory storing computer-executable instructions, where the processing module is configured to access and execute the computer-executable instructions to perform a set of acts. The acts include shifting a frequency associated with the received RF carrier signal to an intermediate frequency (IF). The acts include demodulating the frequency shifted portion of the RF carrier signal associated with the broadcast station, the demodulation resulting in an output signal. The acts further include extracting an embedded data from the demodulated output signal, where the embedded data can be utilized to interact with a party associated the embedded data. The acts further include serving the embedded data in conjunction with the demodulated audio signal.
