Audio data communication method and device in double-transmission mode, equipment and system

Abstract

The invention discloses an audio data communication method and device in a double-transmission mode, equipment and system. The method comprises the steps of: step S100, driving first Bluetooth playing equipment and second Bluetooth playing equipment to carry out link information interaction through an information interaction link established between the first Bluetooth playing equipment and the second Bluetooth playing equipment; step S200, controlling local equipment at a local link sub-event anchor point to receive first current audio data sent to the local equipment by sound source equipment, and during the period, enabling monitoring equipment to monitor the first current audio data; step S300, comparing the communication performance when the local equipment receives the first current audio data with the communication performance when the monitoring equipment monitors the first current audio data to obtain a communication performance comparison result; and step S400, selecting the local equipment or the monitoring equipment with better communication performance to respond to the sound source equipment. In the double-transmission mode, link resources are effectively utilized, the influence of poor data receiving performance caused by external interference is reduced, and the communication quality of the double-Bluetooth playing equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of Bluetooth audio communication, in particular to an audio data communication method, device, device and system in a dual-transmission mode. Background technique [0002] The Bluetooth SIG has added the Bluetooth Low Energy (BLE) audio support function (LEaudio) to the Bluetooth protocol version 5.2. In the application of dual wireless audio communication, such as dual wireless Bluetooth headsets, dual wireless Bluetooth speakers and other scenarios, because the description of the Bluetooth low energy protocol is implemented by using the dual transmission of audio source devices, and each link only transmits the data belonging to its own The mono audio data of the playback device will inevitably have the problem of shortening the dual wireless audio communication distance due to environmental changes and human interference, which makes the standard Bluetooth network communication not meet the applic...

Problems solved by technology

[0010] For the dual wireless audio application of the dual mode BLE protocol, in the standard Bluetooth low energy protocol regulations, there are factors such as environmental changes and human interference, such as the position of the human head in this dual wireless audio communication network, interference The communication of CIS1 or CIS2 will make the performance of TWS Sink1 or TWS Sink2 receive audio data worse. On the one hand, it will cause TWS Sink1 or TWS Sink2 to not respond to the audio source device in time, causing the audio source device to resend audio data all the time, wasting bandwidth resources on the other hand, the quality of the audio data received by TWS Sink1 or TWS Sink2 is poor, which will also lead to a shorter distance or stuttering problems in dual wireless audio communication, which will affect the user experience

[0011] Therefore, in the dual-transmission mode, how to effectively utilize link resources and reduce the impact of poor data reception performance caused by external interference has become an urgent technical problem to be solved.
