[0032] see figure 1 , figure 1 It is a schematic flowchart of a multimedia synchronous playing method provided by the first embodiment of the present invention. The methods include:
[0033] Step S101 , according to the playback delay of the multiple slave devices relative to the master device, perform priority division on the multiple slave devices to obtain the priority of the slave devices.
[0034] It can be understood that the method described in this embodiment mainly describes a playback group composed of multiple playback devices in a multimedia synchronous playback system. In the playback group, multiple playback devices are connected through wired transmission or wireless transmission to form a private network environment. Wherein, the wireless transmission mode may be infrared, bluetooth, WiFi (Wireless Fidelity, wireless local area network), hotspot network, and the like. The private network environment can be connected to one or more routers, and then connecte...

[0051] Please also refer to figure 2 , figure 2 It is a schematic flowchart of a multimedia synchronous playing method provided by the second embodiment of the present invention. The methods include:
[0052] Step S201, divide the multiple slave devices into echelons according to the order of the playback delays of the multiple slave devices relative to the master device from small to large, and obtain echelons corresponding to the slave devices, wherein the echelons include First echelon and second echelon.
[0053] It can be understood that the first echelon and the second echelon are used to distinguish different objects, rather than limiting the number, and the echelon may also include the first, second to Nth echelons.
[0054] It can be understood that the playback delay can be obtained by obtaining data such as the spatial distance between the multiple slave devices and the master device, or the strength of the wireless signal, or the network transmission delay, or...

[0078] see image 3 , image 3 It is a schematic structural diagram of a multimedia synchronous playback device provided by the third embodiment of the present invention. The multimedia synchronous playing device 30 includes a dividing module 31 , a serial number setting module 32 , a cache module 33 , and a synchronous playing module 34 .
[0079] Wherein, the dividing module 31 is configured to divide the priority of the multiple slave devices according to the playback delay of the multiple slave devices relative to the master device, so as to obtain the priority of the slave devices.
[0080] It can be understood that the playback delay can be obtained by obtaining data such as the spatial distance between the multiple slave devices and the master device, or the strength of the wireless signal, or the network transmission delay, or the type of the device solution, or the level of the synchronization error. and obtained after calculation. The playback delay amount may be ...
