[0030] 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:

[0031] Step S101, sending the target play item of the multimedia data in the master device to the slave device.

[0032] 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 connected to the Internet through the routers, so that one or more playback devices in the private network en...

[0049] 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:

[0050] Step S201, sending the playlist of multimedia data in the master device to the slave device, wherein the playlist includes multiple target play items.

[0051] It can be understood that, before synchronous playing, the master device sends the playlist of the multimedia data to be played to the slave device, wherein the playlist carries multiple target play items. The slave device can be single or multiple.

[0052] Wherein, the target play item may include a file name corresponding to the multimedia data, an MD5 (Message-Digest Algorithm 5, message digest algorithm version 5) check code, ID3 information or a link URL, and the like. Among them, the MD5 check code is the check code formed after the multimedia data is encrypted through the hash algorithm, which is uniq...

[0066] 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 sending module 31 , a judging module 32 , and a synchronous playing module 33 .

[0067] Wherein, the sending module 31 is configured to send the target play item of the multimedia data in the master device to the slave device.

[0068] Preferably, before synchronous playing, the sending module 31 sends the target play item of the multimedia data to be played in the master device to the slave device. Wherein, the slave device may be single or multiple; the target play item may be single or multiple.

[0069] Wherein, the target play item may include a file name corresponding to the multimedia data, an MD5 (Message-Digest Algorithm 5, message digest algorithm version 5) check code, ID3 information or a link URL, and the like. Among them, the MD5 check...

Abstract

The invention discloses a multimedia synchronous playing method, device and system, wherein the method comprises the following steps: sending target play items of multimedia data in main control equipment to slave units; and when a judging result shows that a multimedia file fitted with the target play items exists in a slave unit, invoking the multimedia file which already exists in the slave unit and is fitted with the target play items, and performing synchronous playing. As the multimedia file already saved in the slave unit is directly triggered for synchronous playing, cache resources of each slave unit are utilized sufficiently for resource integration, the operating pressure of the main control equipment is reduced, occupation of network bandwidth is reduced, the entire network environment is optimized, network congestion is avoided, synchronous playing becomes smoother and stabler, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of multimedia playing, in particular to a method, device and system for synchronous playing of multimedia. 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 slave d...
