Multimedia data synchronous playing method and device

Abstract

The embodiment of the invention provides a multimedia data synchronous playing method and device, used for realizing multimedia data synchronous playing among a plurality of multimedia playing devices. The multimedia data synchronous playing method comprises: performing clock synchronization with a multimedia playing device according to the data transmission delay time of each multimedia playing device; receiving multimedia data including time labels; and according to clock time after synchronization, target data transmission delay time, the buffer time of each frame of multimedia data in the multimedia playing device, and the playing time of each frame of multimedia data indicated by the time labels, calculating the playback time of each frame of multimedia data, and sending the multimedia data and the playback time of each frame of multimedia data to a plurality of multimedia playing devices so as to indicate the multimedia playing devices to play back multimedia data according to the relation between received playback time of each frame of multimedia data and self clock current time.

Description

technical field [0001] The embodiment of the present invention relates to the field of video technology, and in particular to a method and device for synchronously playing multimedia data. Background technique [0002] For home theaters, the implementation based on Wireless-Fidelity (WIFI) does not require open-wall wiring, and the cost is lower, and WIFI speakers can be shared by home devices such as TVs, mobile phones, and computers, so they are more popular with the public. Accept it, and it is more likely to enter thousands of households. [0003] In the WIFI-based implementation scheme, multiple WIFI speakers are connected to the TV or computer through a router. The audio data between the TV and the WIFI speakers needs to be transmitted through the network, and there may be audio data of each speaker that is not connected to the TV or the computer. The video data of the computer is not synchronized, what's more, the audio data of each WIFI speaker is not synchronized. ...

AI Technical Summary

Problems solved by technology

[0005] Embodiments of the present invention provide a method and device for synchronously playing multimedia data, which are used to solve the problems in the prior art that audio data and video data are not synchronized, and multiple audio data are not synchronized, so that multimedia data can be played in multiple multimedia Synchronized playback between devices
