Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a data synchronization display method, as shown in fig. 1, where the method is applied to a control end of data synchronization display, and includes the specific steps of:
101. a shared link of the data resource is created.
The control end for data synchronous display is an initiating end for data display, and in the application of remote education, the control end is a teacher end for remote education. In the embodiment of the invention, the control end needs to synchronously display the data, and preferably needs to share the displayed data resources, namely courseware content in distance education.
Because the number of the exhibition ends is large, the control end cannot send the data resources to the exhibition ends one by one, so in the embodiment, the control end creates a data sharing link, and the exhibition end actively acquires the data resources through the link. The number of the display ends can be unlimited by the control end. The technology of establishing the shared link is widely applied to the existing network data transmission technology, so the embodiment of the invention does not excessively describe the specific created flow, and the implementation technical mode of the creation is not limited.
It should be noted that the data resource in this embodiment is different from other data in that the data resource includes a plurality of data presentation tags, and the data presentation tags are used for marking different playing schedules of the data resource during playing. The number of the data display tags in the data resource can be set by a user according to the requirement.
102. And sending the data display label according to the playing progress of the data resource.
After the control end completes the creation work of the data resource link, the subsequent data resource playing can be carried out. And the control end sends a corresponding data display label to the display end according to the playing progress during playing. The playing mode in this embodiment may be continuous and dynamic playing, or may be step-by-step playing performed by a control instruction. Accordingly, the data resource suitable for the control end to perform data synchronous display and play in this embodiment may be a streaming media file such as a video, and may also be a format file that can be statically displayed such as a file and a picture. Specifically, the sending mode of the data display label may be that the control terminal actively sends the data display label to the display terminal, and the sent target may be sent by the display terminal which loads the data resource according to a click; or the downloaded exhibition end actively acquires the data exhibition label from the control end.
Corresponding to the data synchronization display method shown in fig. 1, an embodiment of the present invention further provides a data synchronization display method, as shown in fig. 2, where the method is applied to a display end for data synchronization display, and includes the following specific steps:
201. and acquiring the data resource shared by the control end.
The display end of the data synchronous display is equivalent to a client end in the remote education application. In the embodiment of the invention, when the display end needs to synchronously display the content played in the control end, the data resource displayed in the control end is firstly obtained through the shared link created by the control end, and the data resource is loaded to the local display end. The display end plays the data resource locally, so that the problem of data buffering in the playing process of the data resource can be avoided, and the playing delay is caused.
202. And collecting the data display label sent by the control end.
In the process of playing the data resource, in order to ensure that the contents played by the display end and the control end are synchronous, the display end needs to acquire a data display tag sent by the control end, and the playing progress of the data resource is determined through the data display tag. The data display label can be acquired by acquiring the data display label actively sent by the control terminal, or by the display terminal sending a request for acquiring the data display label, and the control terminal responding to the request sending the data display label marked by the playing data resource of the current control terminal.
203. And playing the data resource according to the data display label.
Generally, the playing progress of the display end is slower than the playing progress of the control end when playing the data resource. Therefore, the progress marked by the data display label acquired by the display end is mostly greater than the current playing progress of the display end, and accordingly, the display end only needs to adjust the current playing progress according to the display progress marked by the data display label. For the rare case that the current playing progress is already larger than the progress marked by the data presentation label, the present embodiment is to keep the current playing progress unchanged.
It can be seen from the above implementation manner that, in the data synchronous display method and apparatus adopted in the embodiments of the present invention, the control end provides data resources to the display end, and the control end sends the data display tag to the display end while playing the data resources, so that the display end adjusts the progress of playing the data resources according to the tag, and maintains synchronous display with the data resources played by the control end. Compared with the existing streaming media data synchronization mode, the data synchronization display method adopted by the embodiment of the invention has the advantages that the display end already has the data resource of the control end, in the playing process, the specific playing progress is determined only according to the data display label sent by the control end, and the network resource occupied by the receiving and sending label can basically ignore the requirement on the network environment. Therefore, the efficiency of data synchronous display can be greatly improved, and the problem of synchronous display delay can be reduced.
In order to describe the data synchronization display method proposed in the embodiment of the present invention in more detail, the embodiment of the present invention will describe in detail the synchronization display method completed by the control end and the display end in cooperation through specific examples, as shown in fig. 3, the method includes the specific steps of:
301. the control end creates a shared link of the data resource.
In this embodiment, remote education is specifically described as an example, and existing remote education is online education to a student user by live broadcasting or recorded broadcasting of video. The video content comprises the explanation of the teacher and courseware of the course, and the audio and corresponding courseware content of the explanation of the teacher have practical significance for the synchronous remote education mode. Therefore, courseware contents can be synchronously displayed in the mode of the embodiment of the invention. So as to enlarge the application range of distance education, especially in the region with poor network environment.
Firstly, a control terminal makes data resources, namely remote education courseware. In the process of making data resources, a teacher can edit specific data display tags at different positions in courseware according to needs, specifically, a corresponding data display tag can be set on each different interface of the courseware, and different data display tags can be edited and added to dynamic courseware according to time. And providing the courseware added with the data display tag for a user at the display end through a shared link for downloading and watching.
302. And the control terminal sends the data display label according to the playing progress of the data resource.
The control end starts the process of data synchronous display when playing data resources, and in the process, the control end monitors whether a data display label exists at the current playing position in real time, and if so, extracts the data display label and sends the data display label to the display end. Specifically, in the remote education application, when a teacher gives lessons remotely in real time, whether a data display label is marked at the current position of the courseware played or not can be monitored in real time, if the data display label exists, the label is sent to a student end, and the student end is informed of the playing progress of the courseware at the current teacher end.
303. And the display terminal acquires the data resource shared by the control terminal.
Before the teaching courseware is synchronously displayed on the display end, namely the student end, the courseware needs to be downloaded, the courseware can be clicked and downloaded through the volume sharing link established by the control end, and generally, a corresponding courseware downloading special column can be provided in a remote education platform website.
It should be noted that, in addition to the student users who can download courseware in advance, there are some users who want to watch temporarily after the synchronous display has started, for these users, the remote education platform will provide a link entry, and by clicking the link, the user side will also obtain the courseware currently displayed synchronously first, and judge whether the downloading of the courseware is completed, and if the completion of the downloading of the courseware, the user side will start to play the courseware automatically.
304. And collecting the data display label sent by the control end.
Once the display end starts playing the courseware, the synchronous display of the data resources is shown to be started, at this time, the display end obtains the data display label sent by the control end in real time, when the data display label is collected, the display end judges whether the courseware progress marked by the data display label is behind the current playing progress of the courseware, and if yes, the data display label is confirmed to be an effective label. That is, when the data display tag is obtained, a plurality of tags may be obtained, where some progress information marked by the tags is outdated, and in order to distinguish the tags, the tags need to be identified and determined to find out an effective playing progress tag, and the rule is to distinguish the effectiveness of the tags according to the comparison between the progress recorded by the tags and the current playing progress of the display end.
305. And playing the data resource according to the data display label.
And finally, updating and adjusting the progress of the courseware played currently in the display end according to the progress of the courseware playing recorded in the data display label.
In addition, according to the judgment in step 304, when there are a plurality of the collected effective data display tags, the display end selects one data display tag with the largest progress from the plurality of effective tags, deletes the other effective tags, reads the playing progress recorded in the reserved data display tag, and updates the playing progress to the playing progress currently displayed by the display end.
