Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Embodiment one：
According to embodiments of the present invention, a kind of embodiment of method of data synchronization is provided, it should be noted that in attached drawing
The step of flow illustrates can execute in the computer system of such as a group of computer-executable instructions, although also,
Logical order is shown in flow chart, but in some cases, it can be to execute shown different from sequence herein or retouch
The step of stating.
Fig. 1 is a kind of flow chart of method of data synchronization according to the ... of the embodiment of the present invention, as shown in Figure 1, this method includes
Following steps：
Step S102 obtains time series file, and the time series file includes for playing electronics to be synchronized
The timestamp of the trigger action of the teacher's pointer of handout and triggered time for characterizing the trigger action；The text of time series file
Part format is the data interchange format of lightweight.
In the present embodiment, time series file can be obtained by audio video synchronization software, wherein in the time series
File includes the trigger action of teacher's pointer and the timestamp of trigger action.And in the time series file, including multiple triggerings
Operation, and each trigger action corresponds to a timestamp.Above-mentioned multiple trigger actions are recorded in time sequence according to trigger sequence
In row file.
Step S104 obtains video file to be synchronized and the electronics handout to be synchronized；
In the present embodiment, video file to be synchronized is the video file prerecorded, electronics handout to be synchronized
For video file corresponding with the video file to be synchronized.
Step S106 is based on the time series file by the video file to be synchronized and the electronics to be synchronized
Handout synchronizes operation.
In the present embodiment, based on time series file by video file to be synchronized and electronics handout to be synchronized into
When row is synchronous, first, the initial time of video file to be synchronized and electronics handout to be synchronized is synchronized into processing.So
Afterwards, time series file is imported in audio video synchronization software；Finally, audio video synchronization software will be to be synchronized based on time series file
Video file and electronics handout to be synchronized synchronize processing automatically.
By foregoing description it is found that in the present embodiment, being not necessarily to post-production, can be realized as by time series file
Video file to be synchronized and the processing of the automatic synchronization of electronics handout to be synchronized, convenient and efficient, generalization is high, even if will not grasp
Make the synchronization process that the personnel of computer can use this method to realize video and handout.
In embodiments of the present invention, first, time series file is obtained, wherein time series file includes for broadcasting
Put the timestamp of the trigger action of the teacher's pointer of electronics handout to be synchronized and the triggered time for characterizing trigger action；Then,
Obtain video file to be synchronized and electronics handout to be synchronized；Finally, time series file is based on by video to be synchronized text
Part and electronics handout to be synchronized synchronize operation.

Triggered time establishes correspondence to trigger action and triggered time, to obtain time series file.In time series text
Part includes timestamp to be triggered successively, and the action (paging up, downward page turning etc.) that each timestamp is triggered.
In the present embodiment, it is not necessarily to post-production, video file to be synchronized can be realized as by time series file
It is handled with the automatic synchronization of electronics handout to be synchronized, convenient and efficient, generalization is high, even if the personnel of computer will not be operated all
This method can be used to realize the synchronization process of video and handout.
In another optional embodiment, based on the time series file will the video file to be synchronized with
The electronics handout to be synchronized synchronizes operation and includes the following steps：
At the time of broadcasting since the video file to be synchronized, control the electronics handout to be synchronized according to
The time series file executes corresponding action, wherein corresponding action includes following any：It pages up, to
Lower page turning.
After time series file is directed into audio video synchronization software, video to be synchronized is played in audio video synchronization software
At the time of file, audio video synchronization software controls electronics handout to be synchronized and executes corresponding move according to time series file
Make.For example, at the t1 moment, page up, at the t2 moment, downward page turning etc..
Due to time series file with video to be synchronized be it is synchronous, treated together according to time series file
The electronics handout of step executes after corresponding action, it will be able to realize video file to be synchronized and electronics handout to be synchronized it
Between automatic synchronization, without post-processing.
In another optional embodiment, as shown in figure 3, will be described to be synchronized based on the time series file
It further includes following steps that video file and the electronics handout to be synchronized, which synchronize operation,：
Step S301 plays circuit by first and plays the video file to be synchronized；
