Bluetooth Low Energy Audio Reception via Advertisement Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth technology faces challenges in efficiently receiving and managing audio data, particularly in scenarios with multiple server devices, where users struggle to determine which device to connect to for audio streaming due to lack of clear information on available audio data and synchronization issues.
Innovation Solution
A method using Bluetooth Low Energy technology for receiving audio data, involving advertisement messages with synchronization and transmission timing information, allowing clients to decode audio data based on user permission, and including audio data information in these messages to facilitate user selection and efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth Classic method is used for audio data transmission, then stable connection and management are achieved, but power consumption increases and device complexity increases
Solution Approach 1:
The patent changes the communication parameters by switching from Bluetooth Classic (BR/EDR) to Bluetooth Low Energy (BLE) technology. This parameter change enables audio data reception with lower power consumption while maintaining connection stability through BLE's optimized connection management and advertising mechanisms.
2Adaptability or versatility
If multiple server devices are available for audio streaming, then service versatility increases, but user difficulty in selecting appropriate device increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the client device receives and processes advertisement messages from multiple server devices, extracting and presenting audio data information to the user. This intermediary role simplifies the user's task by pre-processing device information and presenting it in a manageable format for selection.
Solution Approach 2:
The patent segments the information from multiple server devices into structured advertisement messages containing specific audio data information. This segmentation allows the user to see distinct, organized information from each device rather than a overwhelming list, making device selection easier while maintaining service versatility.
3Device complexity
If audio data information is not included in advertisement messages, then message simplicity is maintained, but user ability to make informed selection deteriorates
Solution Approach 1:
The patent applies preliminary action by including audio data information in advertisement messages before the actual audio data transmission. This allows users to make informed selections about which device to connect to based on pre-presentation of audio content information, without adding significant complexity to the message structure.

AI summary
A method for receiving audio data using Bluetooth Low Energy technology comprises: receiving, from a server device, a first advertisement message including information for providing an audio streaming service and a second advertisement message including synchronization information for synchronization between the client device and the server device; receiving, from the server device, a third advertisement message including transmission timing information of the audio data related to the audio streaming service, wherein audio data information for providing information on the audio data is included in at least one of the second advertisement message and the third advertisement message; receiving, from the server device, the audio data through isochronous channel; obtaining, from an user, specific information related to whether to permit a provision of the audio streaming service based on the audio data information; and decoding the audio data based on the specific information representing permission to provide the audio data.
