Bluetooth Data Interception for Multi-Device Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth technologies are limited in their ability to efficiently transmit data to multiple audio playback devices simultaneously, as they typically allow only one data output source to connect with one audio playback device, requiring additional protocols for secondary devices to receive data, which can lead to incomplete data integrity and increased bandwidth usage.
Innovation Solution
Implementing a data interception mode in Bluetooth communication that allows unidirectional acquisition of data packets by secondary devices during a portion of the communication process, enabling multiple audio playback devices to receive data from a single data source without bidirectional communication, and ensuring data integrity through packet checking and missing packet retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a data source device connects to only one audio playback device via Bluetooth, then the Bluetooth connection is simple and stable, but the data source cannot transmit data to multiple audio playback devices simultaneously
Solution Approach 1:
The patent introduces a primary audio playback device as an intermediary between the data source device and secondary audio playback devices. The primary device receives data packets from the data source via Bluetooth and forwards them to secondary devices, enabling multi-device connectivity while maintaining a simple Bluetooth connection structure (data source → primary device → secondary devices).
Solution Approach 2:
The patent segments the audio playback function into primary and secondary roles. The primary device handles Bluetooth communication with the data source, while secondary devices receive data forwarded by the primary device. This segmentation allows the system to support multiple playback devices without requiring the data source to maintain multiple Bluetooth connections simultaneously.
2Adaptability or versatility
If data is transmitted from one audio playback device to another via Bluetooth or other protocols, then multi-device playback is achieved, but bandwidth usage increases and data integrity may be compromised
Solution Approach 1:
The patent implements partial data transmission by having the primary audio playback device forward only selected data packets to secondary devices, rather than transmitting all data. The system determines which packets need forwarding based on playback requirements, reducing unnecessary bandwidth consumption while still achieving multi-channel playback capability.
3Adaptability or versatility
If additional forwarding processes are used to transmit data to secondary devices, then multiple audio playback devices can receive data, but the data load and bandwidth occupation increase
Solution Approach 1:
The patent extracts only the necessary data packets from the complete data stream for forwarding to secondary devices. The primary audio playback device selectively forwards specific packets based on playback requirements, rather than transmitting the entire data set, thereby reducing data load while maintaining multi-device distribution capability.
Data Source
AI summary
A method and a system for Bluetooth communication, and an electronic device are disclosed. The method includes: acquiring data packets from a data source device by means of data interception within at least a portion of a time period in a Bluetooth communication process, wherein the data interception is a working mode that allows unidirectional acquisition of data packets delivered by the data source device in the Bluetooth communication process.
