Embodiment Construction

[0049] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0050] join figure 1 , the present invention proposes a method for realizing multi-screen linkage, including:

[0051] Step 100, respectively determine the first difference between the system time of each mobile terminal and its own system time. Specifically include:

[0052] Sending a system time feedback request to each mobile terminal; receiving the system time from each mobile terminal, calculating the first difference between the system time of each mobile terminal and its own system time respectively.

[0053] Step 101, respectively determine the comp...

Abstract

The present invention discloses a method and device of realizing synchronous playing. The method comprises the steps of separately determining the first differences between the system time and the own system time of mobile terminals; separately determining the complexities and the playing time delays of the playing files that can be processed by the mobile terminals; determining the complexities of the to-be-played files according to the complexities of the playing files that can be processed by the mobile terminals; sending the to-be-played file data to the mobile terminals capable of processing the determined complexities according to the first differences and the playing time delays of the mobile terminals capable of processing the determined complexities to realize the synchronous playing. According to the method of the present invention, by comparing the first differences between the system times of the mobile terminals and the playing time delays of the mobile terminals, the synchronous playing is realized, and the playing time delays of the mobile terminals are reduced.

Description

technical field [0001] The invention relates to terminal technology, in particular to a method and device for realizing synchronous playback. Background technique [0002] There are more and more scenarios of multi-screen linkage. For example, there is a TV box at home that supports the Miracast function, that is, the TV box and the TV are connected through a high-definition multimedia interface (HDMI, High Definition Multimedia Interface) cable. When the mobile terminal and the TV box are directly connected through Miracast, they can simultaneously display pictures or play audio and video on the mobile terminal and the TV. For another example, in a department store, interactive content appears on the big screen, such as grabbing red envelopes. After the server of the department store establishes a connection with the mobile terminal through Miracast, it can simultaneously display the activity content on the large screen and the mobile terminal. [0003] In the prior art, M...
