Audio Identifier Synchronization for Context-Aware Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio replaying terminals lack effective methods for dynamically synchronizing complementary content with broadcasted audio, failing to provide context-aware and personalized experiences for users.
Innovation Solution
The system uses unique audio identifiers encoded into high-frequency audio signals, which are broadcast and detected by mobile devices, allowing for dynamic synchronization of complementary content based on user context, location, and other factors, enabling context-sensitive rendering of visual and interactive content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional audio broadcasting is used without unique identifiers, then the system is simple and easy to implement, but dynamic synchronization of complementary content cannot be achieved
Solution Approach 1:
The patent introduces unique audio identifiers as an intermediary element embedded within the audio broadcast signal. These identifiers act as mediators that enable the receiving device to recognize and synchronize complementary content with the audio playback without requiring complex direct communication protocols between the broadcaster and receiver. The identifier serves as a bridge that carries synchronization information through the audio channel itself.
Solution Approach 2:
The audio broadcast signal is segmented to include distinct unique identifiers at specific intervals or transitions. This segmentation allows the receiving device to detect these identifiers independently from the main audio content, enabling precise synchronization points for delivering complementary content without interfering with the overall audio broadcasting system.
2Ease of operation
If context-aware personalized content is provided, then user experience is enhanced, but data processing requirements and system resources increase
Solution Approach 1:
The system performs preliminary actions by pre-processing and caching complementary content locally on the user's device based on predicted context needs. When a unique audio identifier is detected, the device can immediately retrieve and display the corresponding pre-prepared content without requiring extensive real-time data processing or network requests, thereby reducing energy consumption during actual synchronization events.
Solution Approach 2:
The patent implements local quality by processing and storing context-specific content locally on the user's device rather than relying on continuous cloud processing. This allows the device to efficiently handle context-aware content delivery using local resources, reducing the need for energy-intensive remote data processing while still providing personalized experiences.
3Measurement precision
If high-frequency audio signals with encoded identifiers are broadcast, then synchronization precision is improved, but the audio signal may become imperceptible or interfere with regular audio content
Solution Approach 1:
The unique audio identifiers are transmitted using periodic modulation at high frequencies that are perceptible as subtle variations rather than continuous high-frequency noise. This periodic encoding allows the synchronization information to be embedded in a way that maintains audio quality while providing precise detection points for synchronization, using techniques like frequency modulation at intervals rather than continuous high-frequency signaling.

AI summary
Methods and systems for dynamically providing content complementary to a content being rendered on mobile devices based on determining a context of the device based on identifying an encoded unique audio identifier. The transmission and playback of the complementary content is synchronized with the currently rendered content by dynamically taking into account the context of a user operating the mobile device. The context of a user may be built from considering a piece of currently rendered content, characteristics of a profile of a vendor, characteristics of the individual user and/or the user's individual profile, date, time of day and/or further additional information. The context may further take into account the current position and/or location of the user as acoustically triangulated based on sending and/or receiving unique audio identifiers as a high frequency audio signal.
