Embodiment 1

[0034] This embodiment will be described from the perspective of a multimedia synchronous playback device. The multimedia synchronous playback device can specifically be integrated into a playback device, and the playback device can be a playback device such as a terminal (smart phone, tablet computer, etc.), a speaker, or the like.

[0035] A multimedia synchronous playback method, comprising: playing buffered media packets, then detecting whether the system clock is synchronized with the system clock of a reference playback device, if not, obtaining the current playback progress information of the reference playback device, and according to the playback progress The information determines the current target media data package to be played from the cached media data package, and plays the target media data package.

[0036] like figure 1 As shown, the multimedia synchronous playback method, the specific process may include:

[0037] 101. Play the buffered media data packet. ...

Embodiment 2

[0078] According to the multimedia synchronous playing method described in the first embodiment, an example will be given below for further detailed description.

[0079] In this embodiment, a detailed description will be made by taking the integrated multimedia synchronous playing device described in the first embodiment in the slave device as an example.

[0080] refer to figure 2 , the present embodiment provides a multimedia synchronous playback system, including: a source device 10, a master device 20, and at least one slave device 30; the source device 10, the master device 20, and the slave device 30 can be connected to each other through a network .

[0081] Wherein, the main control device 20 is used to control the slave device, which can be a terminal, such as a mobile phone, a tablet computer, etc., and the main control device can also be a playback device, such as a playback device such as a speaker; this embodiment will use the main control device 20 The termin...

Embodiment 3

[0118] In order to better implement the above method, an embodiment of the present invention also provides a multimedia synchronous playback device, which can be integrated into a playback device, and the playback device can be a smart phone, a tablet computer, a speaker, and the like.

[0119] like Figure 4 As shown, the multimedia synchronous playback device 400 may include: a playback unit 401, a detection unit 402, an acquisition unit 403, and a synchronization unit 404, as follows:

[0120] A playback unit 401, configured to play the buffered media packets;

[0121] A detection unit 402, configured to detect whether the system clock is synchronized with the system clock of the reference playback device;

[0122] The obtaining unit 403 is used to obtain the current playback progress information of the reference playback device when the detection unit 402 detects that the system clock is not synchronized with the system clock of the reference playback device;

[0123] Th...

Abstract

The embodiments of the invention provide a multimedia synchronous play method, apparatus and system, and a terminal. According to the embodiments of the invention, a cached media data packet is played, then whether a system clock synchronizes with a system clock of a reference play device is detected, if not, current play progress information of the reference play device is obtained, according to the play progress information, a target media data packet currently needing to be played is determined from the cached media data packet, and the target media data packet is played. According to the scheme, multimedia play synchronization between multimedia play devices can be improved.

Description

technical field [0001] The present invention relates to the technical field of synchronous playback, in particular to a multimedia synchronous playback method, device, system and terminal. Background technique [0002] With the improvement of living standards, home audio-visual equipment plays an important role in people's lives. At present, it has been widely used to connect multiple multimedia playback devices (for example, speakers, players, etc.) and control devices to each other through a wired or wireless network to form a multimedia playback system, and to play the same multimedia such as music synchronously. [0003] In the above multimedia playing system, each multimedia playing device has an independent clock system. Each playback device plays multimedia according to its own clock system. However, the clock systems of various multimedia playback devices and reference devices (generally control devices) are not always synchronized. There may be a slight time diff...
