Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
In embodiments of the present invention, provide a kind of document handling method, Fig. 1 is the flow chart of the document handling method according to the embodiment of the present invention, and as shown in Figure 1, this flow process comprises the steps:
Step S102, server receives the document files that the first client sends;
Step S104, server converts the document file to multiple picture file according to number of pages, wherein, one page of a corresponding the document file of picture file;
Step S106, the plurality of picture file is sent to multiple client by server, and the plurality of client comprises this first client and other clients;
Step S108, server receives the control information from this first client, and wherein, this control information is that the picture file that this first client is switching display sends;
Step S110, server sends order to this other client, and wherein, this order is used to indicate these other clients and the picture file of display is switched to the identical picture file with the current display of this first client.
Pass through above-mentioned steps, convert document files to picture, the definition of picture will be clear that many relative to the document files that camera is taken, thus solve in correlation technique the problem affecting result of use of imparting knowledge to students or not known by camera shooting teaching courseware in the application of meeting class and causing, improve Consumer's Experience.
In one preferred embodiment, can on the server by one independently service carry out the conversion of document, this process can improve the efficiency of document subject feature vector.Such as, can run a conversion process on the server, this process independently serves existence as one, and this conversion process converts the document file to the plurality of picture file according to number of pages, wherein, this conversion process is used for the document file transform to become picture file.
In another one preferred implementation, the content of teaching can also be recorded.Generally, only recorded video file, in the preferred embodiment, not only records video file, can also record document files.When playing the file recorded, need the stationary problem considering video file and document files page turning.Such as, proceed to carry out page turning when 01 points in 1 hour at course, now need to consider this problem when return visit.In the preferred embodiment, server record video file in joining day label (such as, can be marked by the mode of XML), wherein, the time of this time tag record is the time that this first client switches the picture file of current display, the picture file of current display, when being played to this time tag, is switched to picture file corresponding to this time tag by this video file.
Preferably, when server converts the document file to multiple picture file failure according to number of pages, this server sends information to this first client, and wherein, this information is used for changing the failure of the document file to this first Client-Prompt.
When needing the document files of conversion many, can adopt the measure of load balancing, such as, document files to be converted, when this server is busy, is sent to another server by server; This another server converts this document files to be converted to multiple picture file, and the multiple picture files be converted to are sent to this server.
