[0036] 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:

[0037] Step S101, acquiring communication status indicators between a master device and a slave device among multiple playback devices.

[0038] 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. Wherein, 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 connected to the Internet through the routers, so that one or more playback ...

[0053] 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:

[0054] Step S201, acquiring communication status indicators between a master device and a slave device among multiple playback devices.

[0055] For example, when the multimedia playback system is started, a communication connection is established between a plurality of playback devices, that is, a communication connection is established between the master device and the slave device, and between the slave device and the slave device, for monitoring the operation of the device. status and communication status between devices.

[0056] When starting to play, the master device sends media data to the at least one slave device for synchronous playback. That is, the master control device acts as the media data source device of all slave devices when playing starts.

[0092] see Figure 4 , Figure 4 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 first acquisition module 31 , a first interruption module 32 , a first selection module 33 , and a first sending module 34 .

[0093] Wherein, the first acquiring module 31 is configured to acquire a communication status indicator between a master device and a slave device among multiple playback devices.

[0094] The first acquisition module 31 can obtain the information between the master device and the slave device among multiple playback devices by monitoring the network delay between the slave device and the master device, or the transmission packet loss rate, or the retransmission rate, etc. Communication status indicator between.

[0095] The first interruption module 32 is configured to disconnect the connection between the master device and...

Abstract

The invention discloses a synchronized multimedia playing method, a synchronized multimedia playing device, a terminal and a synchronized multimedia playing system. The synchronized multimedia playing method includes obtaining a communication state index between a master control device and a corresponding slave device, disconnecting the master control device from the corresponding slave device when the communication state index is lower than a first preset threshold value, selecting a target playing device for providing media data for the slave device from multiple playing devices and sending a control command so as to enable the target playing device to provide the media data for the slave device according to the control command. The synchronized multimedia playing method has the advantages that the target playing device in a better state is dynamically adjusted as a media data source device to substitute for or assist the master control device to transmit the media data, so that influences on network bandwidth and system resources are reduced and running pressure of the master control device is relieved.

Description

technical field [0001] The present invention relates to the technical field of multimedia playback, in particular to a multimedia synchronous playback method, device, terminal and system. Background technique [0002] Multiple playback devices (such as mobile phones, computers, speakers, various players, etc.) are connected through wired or wireless network technology to form a multimedia synchronous playback system, which plays the same audio, video or picture synchronously, which has been widely used. Taking the multimedia synchronous playback system as an example, how to realize the synchronous playback of multiple playback devices, so that the sound or picture delay between multiple devices is as small as possible, so as to ensure the user's sense of hearing or visual consistency, this is multi-device synchronization Key technologies for playback. [0003] For example, among multiple playback devices that realize synchronous playback, when the master device and other sl...
