Audio Gateway for Multi-Device Bluetooth Stream Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth audio technologies are not suited for supporting audio data transmission/reception between multiple devices, leading to delays and increased power consumption for device discovery, especially in M-to-N connection scenarios where ambiguity occurs regarding which audio stream to process.
Innovation Solution
A method and apparatus for controlling audio data in a wireless communication system by obtaining an audio policy, receiving information on multiple audio streams from other devices, selecting audio streams based on the received information and the audio policy, and performing a setup procedure for the selected audio streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Bluetooth audio technology is used for one-to-one connection, then audio transmission between two devices is supported, but it cannot support audio data transmission/reception between multiple devices in M-to-N connection scenarios
Solution Approach 1:
The audio gateway device is designed to handle multiple audio streams simultaneously from different audio source devices, enabling it to function as a universal audio hub that supports both one-to-one and many-to-many connection scenarios. The device can process multiple audio streams with different priorities and route them to appropriate audio sink devices.
Solution Approach 2:
An audio gateway device is introduced as an intermediary between multiple audio source devices and audio sink devices. This mediator manages the complexity of M-to-N connections by centralizing the audio stream processing and routing functions, allowing multiple devices to connect without requiring complex peer-to-peer coordination.
2Adaptability or versatility
If multiple audio streams are transmitted in M-to-N connection, then audio data transmission between multiple devices is enabled, but ambiguity occurs as to which audio stream is to be processed
Solution Approach 1:
The system introduces priority parameters for different audio streams to resolve ambiguity. Each audio stream is assigned a priority level, and the audio gateway device uses these priority parameters to determine which streams to process and transmit. This parameter-based differentiation allows multiple audio streams to coexist without confusion.
Solution Approach 2:
The audio stream management is segmented into different priority levels, with high-priority streams (such as voice calls) being processed separately from low-priority streams (such as music playback). This segmentation allows the system to handle multiple streams systematically by dividing them into distinct processing categories.
3Adaptability or versatility
If device discovery is performed in M-to-N connection scenarios, then multiple audio devices can be found and connected, but power consumption increases
Solution Approach 1:
The audio gateway device pre-establishes connections with multiple audio source and sink devices before actual audio streaming begins. This preliminary connection setup allows the gateway to have advance knowledge of available devices, reducing the need for continuous device discovery operations during audio playback and thereby lowering power consumption.
