The playback device whose bluetooth module is turned on may include an execution end, or may not include an execution end.

However, since the number of sound source devices scanned in step 101 may be multiple, preferably, the number of playback devices whose Bluetooth modules are turned on is the same as the number of sound source devices. This setting method can realize the one-to-one correspondence between the audio source device and the playback device with the Bluetooth module turned on, which facilitates the establishment of Bluetooth connections between the audio and video playback system and all scanned audio source devices.

After the playback device in the audio and video playback system establishes a private network, any two playback devices can communicate with each other to transmit data information. After determining the working state of the bluetooth module of each playback device, controlling the working state of the bluetooth module of the playing device can be specifically: the execution end directly controls the working state of its own bluetooth module, and at the same time sends a corresponding message to the rest of the playing devices The bluetooth module working state control command, after the remaining playback devices receive the bluetooth module working state control command, adjust the working state of their respective bluetooth modules to the working state corresponding to the bluetooth module working state control command.
