Audio Data Transmission via Third-Device Capability Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly with Bluetooth technology, there is a challenge in efficiently transmitting audio data between devices without a display or user interface, as the complexity of connection, management, and disconnection increases, and existing methods do not effectively determine optimal audio data output settings for multiple devices in a multi-channel surround system.
Innovation Solution
A method and apparatus for a third device to receive capability information from first and second devices regarding their audio data output capabilities, determine channel establishment based on this information, and transmit configuration information for audio data transmission, including position and timing adjustments, to ensure effective audio data output in a short-range wireless communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth devices connect and exchange data using traditional discovery and connection methods, then wireless communication between devices is enabled, but the complexity of connection management and control increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-establishing connection information between devices before actual audio data transmission is needed. Devices store connection details in advance, allowing them to quickly resume communication without going through complex discovery and pairing processes again, thus reducing connection management complexity while maintaining ease of operation
Solution Approach 2:
The patent implements self-service through automatic connection management where devices autonomously handle connection establishment, maintenance, and disconnection based on predefined conditions and stored connection information. This reduces the need for manual intervention and simplifies user operation while managing connection complexity automatically
2Adaptability or versatility
If multiple devices are connected in a multi-channel surround system, then audio data transmission capabilities are enhanced, but the complexity of determining optimal output settings increases
Solution Approach 1:
The patent applies feedback by having devices exchange capability information about their audio output features (such as supported formats, power levels, and channel configurations). Based on this feedback, the system automatically determines optimal output settings for each device in the multi-channel surround configuration, enabling versatile audio output while keeping setting management simple through automated adaptation
