Hearing Device Configuration for Secure Multicast Audio Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing devices struggle to selectively receive a specified audio stream in multicast environments due to overlapping audio fields and the inability to discern between competing audio programs, and there is a need for secure communication links to prevent unauthorized access.
Innovation Solution
Hearing devices are configured to receive configuration parameters via a second communication link distinct from the audio streaming link, enabling them to selectively receive a specified audio stream by detecting program identifiers and, in some cases, using cryptographic keys, while maintaining secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hearing devices use standardized wireless communication protocols to receive audio streams, then ease of connection is improved, but the ability to selectively receive specified audio streams in multicast environments deteriorates
Solution Approach 1:
The patent introduces configuration parameters as an intermediary mechanism that mediates between the audio stream and the hearing device. These parameters, transmitted via a second communication link, enable the device to identify and select specific audio streams from multiple overlapping broadcasts, resolving the contradiction between ease of connection and selective reception capability
Solution Approach 2:
The communication system is segmented into two distinct links: a first communication link for audio streaming and a second communication link for transmitting configuration parameters. This segmentation allows each link to serve its specific function optimally, with the configuration parameters enabling selective stream identification without complicating the audio transmission itself
2Reliability
If hearing devices implement secure communication links to prevent unauthorized access, then security is improved, but device complexity increases
Solution Approach 1:
Configuration parameters serve as a secure intermediary that carries authentication information between the audio source and the hearing device. By using these parameters as a mediator for security verification, the system achieves secure communication without requiring complex cryptographic protocols directly within the hearing device
Solution Approach 2:
The system performs preliminary authentication by transmitting configuration parameters before establishing the audio stream reception. This preliminary action verifies the device's authorization status in advance, allowing secure audio reception without ongoing complex security verification during playback
Data Source
AI summary
A hearing device adapted for use by a wearer comprises an audio streaming circuit configured to receive electromagnetic audio streaming via a first communication link. A configuration circuit is configured to receive configuration parameters via a second communication link different from the first communication link for configuring the hearing device to receive the electromagnetic audio streaming. Control circuitry of the hearing device configures the hearing device to enable reception of the electromagnetic audio streaming in accordance with the received configuration parameters.
