Title:
SYNCHRONOUS PLAYING METHOD OF MULTIPLE PLAYING DEVICES AND PLAYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/140746
Kind Code:
A1
Abstract:
Disclosed in the present invention is a synchronous playing method of multiple playing devices, comprising: a second playing device receives Bluetooth information of a first playing device; obtain a first playing progress of the first playing device according to the Bluetooth information, and a local time of the first playing device and the time difference with the standard time, so as to obtain a first standard moment when the first playing device sends the Bluetooth information; obtain a second standard moment when the second playing device receives the Bluetooth information according to a local time of the second playing device and the time difference with the standard time; obtain the network delay time difference of the Bluetooth information according to the first standard moment and the second standard moment, add the network delay time difference to the first playing progress, and calculate a second playing progress of the second playing device; and switch the playing progress of the second playing device to the second playing progress. According to the present invention, synchronous playing of multiple playing devices can be implemented by means of BLE advertising control code information.
