Audio Embedded Control for Dynamic Software Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling software execution lack the ability to dynamically modify program behavior based on external content, particularly in industrial settings where safety and process-specific conditions require real-time adjustments without relying on extensive content-specific databases.
Innovation Solution
Embedding control information in audio or video content signals, using subliminal audio decoders and program managers within user devices to modify software execution, allowing for real-time adjustments based on embedded control signals that are independent of the content itself, enabling safety enhancements and dynamic user interface modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control information is embedded in audio content to modify software execution dynamically, then adaptability and real-time control are improved, but device complexity increases due to requiring subliminal audio decoders and program managers
Solution Approach 1:
The audio content serves dual purposes: as the primary media content for user consumption and as a carrier for embedded control information. The subliminal audio decoder extracts control information from the same audio stream that users listen to, making the audio content universal for both entertainment and control functions simultaneously.
Solution Approach 2:
The subliminal audio decoder acts as an intermediary component that extracts control information from audio content without interfering with the primary audio playback function. This mediator enables control signal transmission through the audio channel while maintaining the integrity of the original content delivery.
2Measurement precision
If extensive content-specific databases are used to control software execution, then measurement precision and control accuracy are improved, but loss of time and processing overhead increase
Solution Approach 1:
Control information is embedded in the audio content during content creation or distribution, preparing the control signals in advance. This eliminates the need for real-time database queries and processing during software execution, as the control instructions are already packaged with the audio content.
Solution Approach 2:
The control information is extracted directly from the embedded audio content through the subliminal audio decoder, bypassing the need for separate database lookups. This extraction approach retrieves control data directly from the audio stream itself, reducing processing overhead compared to database-based systems.
