DETAILED DESCRIPTION 30 To better describe the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention are described in details below with 4 7637693_1 (GHMatters) P102760.AU PETAK reference to the enclosed drawings. Referring now to FIG. 1, therein is shown a structural schematic of a team voice instrument in embodiments of the present invention. The team voice instrument can include at least a terminal 5 110 and a server 120. The terminal 110 can be an electronic device, such as a computer, a smart phone, a tablet, or e-book reader. The electronic device can install an application client of the team voice instrument, or a browser. The electronic device can access a web client of the team voice instrument via the browser. The terminal 110 can be categorized by users, such as teacher terminals used by teachers 10 and student terminals used by students. The teacher is a user teaching lecture files. The teacher can upload the lecture files to the server 120. The server 120 can process the lecture files and send the processed lecture files to the teacher terminals and the student terminals. The students are users learning the lecture files. The students can receive and display the processed lecture files from the server 120. In this embodiment of the present invention, the teacher terminals and the 15 student terminals are in the same teaching channel. The server 120 can be connected to the terminal 110 via wired or wireless network. The server 120 can be one server, multiple servers, or a cloud computation center. In other words, the server 120 can be implemented by one server or a combination of multiple servers, wherein each of the multiple servers can provide same or different functions, such as a register and login server, 20 a client portrait storage server, a channel information and configuration storage server, or a picture and video storage server, etc. The server 120 can be implemented by the cloud computation center, wherein the cloud computation center is a virtual computation platform with a cluster of servers. Referring now to FIG. 2, therein is shown a flow chart of a file sharing method in one embodiment of the present invention. The embodiment of the present invention describes the file 25 sharing method applied to the implementing environment shown in FIG. 1 as an example. The file sharing method includes following steps. Step 201, the terminal sends a file to the server, wherein the file can include a file generated by the terminal, or transmitted to the terminal from other equipment. The embodiment of the present invention does not restrict sources of the file. The terminal can send the file to the server 30 via wired or wireless network. Step 202, the server receives the file from the terminal, wherein the server can receive the 5 7637693_1 (GHMatters) P102760.AU PETAK file from the terminal via wired or wireless network, which corresponds to the manner of sending file of the terminal. Step 203, the server generates a shared address set of the file. When the file sent from the terminal includes multiple pages, the server can decompose the file to multiple file pages and 5 generate one of shared addresses for each of the file pages such that the terminal can download one of the file pages in accordance with each of the shared addresses. Or, the terminal can generate one shared address for a plurality of the file pages, such that the terminal can download the plurality of the file pages in accordance with the shared address, to reduce the interaction between the terminal and the server, resulting in improvement of the downloading efficiency. 10 Preferably, the server can group the shared addresses as the shared address set and send the shared address set to the terminal, to save communication resources comparing with sending each of the shared addresses to the terminal individually. Step 204, the server feedbacks the shared address set to the terminal. The server can send the shared address set to the terminal, to avoid the problems in prior art of the terminal uploading the 15 file pages to and receiving the shared addresses from the server individually and repeatedly, resulting in saving communication resources and reduction of the cost. Specifically, the server can feedback the shared address set to the terminal via wired or wireless network. Step 205, the terminal receives the shared address set feedback from the server. Specifically, 20 the terminal can receive the shared address set from the server via wired or wireless network. Step 206, the terminal shares the shared address set with other terminals. The terminal can share entire or a portion of the shared addresses of the shared address set with the other terminals. The other terminals can download the file from the server in accordance with the shared addresses. 25 In summary, the file sharing method provided by the embodiment of the present invention includes, receiving a file from a terminal, generating a shared address set of the file, feedbacking the shared address set to the terminal, the terminal sharing shared addresses of the shared address set with other terminals. The method of the embodiment of the present invention resolves the problems in the prior art of increased interactions between the server and the terminal caused by 30 uploading the decomposed file pages to the server individually and repeatedly, when the file has 6 7637693_1 (GHMatters) P102760.AU PETAK multiple pages, resulting in saving communication resources and reduction of the cost. Referring now to FIG. 3A, therein is shown a flow chart of a file sharing method in another one embodiment of the present invention. The embodiment of the present invention describes the file sharing method applied to the implementing environment shown in FIG. 1. The difference 5 between the current embodiment and the embodiment shown in FIG. 2 is that, a server can convert the file format of a received file, and share the converted file. The file sharing method can comprises following steps. Step 301, a terminal sends a file to the server. The file can be generated by the terminal. Or, when the file format is not commonly supported by the terminal, the predetermined application 10 supporting the file format is not commonly used, or the installation of the predetermined application is complicated. The terminal can fetch the file from other equipment to avoid the installing and calling of the predetermined application. The embodiment of the present invention does not restrict file sources. The terminal can sent the file to the server, wherein the file format of the file can be the file 15 format when the file is created, or the file format after the file is converted. The embodiment of the present invention does not restrict the file format. For example, the terminal can send the server a PPT file. The PPT file can be created by the OFFICE, or converted from files with other file formats by the OFFICE. In general, the file can include multiple pages. To reduce the interaction between the terminal 20 and the server, the terminal can send a plurality of the file pages altogether to the server. Further, the terminal can send a plurality of the file altogether to the server. Specifically, the terminal can send the file to the server via wired or wireless network. Step 302, the server receives the file from the terminal. The server can receive the file from the terminal via wired or wireless network. 25 Step 303, the server can convert the file format. Because the server is pre-installed a predetermined file format conversion application, the server can call the predetermined file format conversion application after receives the file. The server can convert the file format of the file with the predetermined file format conversion application and generate a converted file. 30 Specifially, the file format conversion can include decomposing the file into a plurality of the 7 7637693_1 (GHMatters) P102760.AU PETAK file pages, and converting each of the file pages to one of the converted file pages with a predetermined file format. If the file includes a plurality of pages, the server can decompose the file into a plurality of the file pages, and convert the file format of each of the decomposed file pages to the 5 predetermined file format. The predetermined file format can be a default or a specified file format, such as an image format or a text format. The converted file pages can refer to the file pages after the file format conversion. Typically, the server can enable a system mode. In the system mode, the predetermined file format conversion application can only convert one file at a time, resulting in a lower file 10 conversion efficiency. The system mode may be system user accounts. Therefore, if there are at least two files, the file format conversion may include: enabling at least two system modes in parallel; and converting the files in turn in each of the system modes with the predetermined file format conversion application pre-installed in the server. 15 For example, when the server installs WINDOWS system, the WINDOWS system can set up at least two user accounts. Since each of the user accounts can call the OFFICE to convert one PPT file, parallel logging on to the at least two user accounts can convert at least two PPT files in parallel, resulting in improvement of the conversion efficiency. The version of the predetermined file format conversion application installed on the terminal 20 may be various. Different version of the predetermined file format conversion application may convert the file differently. For example, a lower version of the predetermined file format conversion application may convert the file with a lower conversion quality. Therefore, the server can install the latest version of the predetermined file format conversion application and convert all of the files from terminals with the latest version to avoid lower conversion quality and 25 conversion inconsistency among the different terminals. Further, the server can configure conversion parameters of the predetermined file format conversion application, to further improve the file conversion quality. Specifically, before enabling at least two system modes in parallel, the server can configure conversion parameters for a predetermined file format conversion application. Then, converting the files in turn via the 30 predetermined file format conversion application installed in the server includes converting the 8 7637693_1 (GHMatters) P102760.AU PETAK files in turn via the predetermined file format conversion application configured with the conversion parameters. For example, OFFICE can configure a picture resolution when a PPT file is converted to a picture. The server can configure the picture resolution in accordance with the conversion 5 requirement. Step 304, the server generates the shared address set. When the file sent by the terminal includes multiple pages, the server can generate one of the shared addresses for each of the converted file pages, so the terminal can download one of the converted file page in accordance with the one of the shared addresses. Or the server can generate one shared address for multiple 10 converted file pages, so the terminal can download multiple converted file pages in accordance with the shared address, to reduce the interaction between the terminal and the server, resulting in improvement of the downloading efficiency. Typically, each of the shared addresses of the shared address set can correspond to one or multiple converted file pages. Preferably, the server can combine the generated shared addresses of the file pages as the 15 shared address set and send the shared address set to the terminal, to save the communication resources than sending the shared addresses to the terminal one at a time. Step 305, the server can feedback the shared address set to the terminal. The server can send the shared address set to the terminal, to avoid the waste of communication resources in the prior art cause by the terminal uploading the decomposed file pages to and receiving the shared 20 addresses from the server individually and repeatedly, resulting in saving of communication resources and reduction of the cost. Specifically, the server can feedback the shared address set to the terminal via a wired or wireless network. Step 306, the terminal can receive the shared address set from the server. Specifically, 25 corresponding to how the server feedbacks the shared address set, the terminal can receive the shared address set from the server via a wired or wireless network. Further, after receives the shared address set from the server, the terminal can download the file pages corresponding to the shared addresses of the shared address set. If the terminal needs to acquire the converted file, after receiving the shared address set, the 30 terminal can acquire the converted file from the server in accordance with the shared address set. 9 7637693_1 (GHMatters) P102760.AU PETAK For example, the terminal can acquire the file pages in accordance with the shared addresses of the shared address set in sequence. Or, the terminal may acquire a plurality of the file pages in parallel in accordance with a plurality of the shared addresses of the shared address set. Step 307, the terminal shares the shared addresses of the shared address set with other 5 terminals. The terminal can share entire or a portion of the shared addresses of the shared address set with the other terminals. The other terminals can acquire the converted files from the server in accordance with the shared addresses. Preferably, the terminal may confirm that the file pages corresponding to the shared addresses of the shared address set are acquired successfully, before the terminal shares the shared 10 addresses with the other terminals, in order to improve file sharing success rate in other terminals. In particular, the terminal sharing the shared addresses of the shared addresses set with other terminals can include: sending the shared addresses of the shared addresses set to a predetermined equipment, and the predetermined equipment broadcasting the shared addresses of the shared addresses set to the 15 other terminals. In the embodiment of the present invention, the terminal may share or broadcast the shared addresses of the shared addresses set to the other terminals directly. Or, the terminal can send the shared addresses of the shared addresses set to the predetermined equipment, and the predetermined equipment can broadcast the shared addresses of the shared addresses set to the 20 other terminals. Wherein, before send or broadcast the shared addresses, the terminal or the predetermined equipment may need to determine the other terminals receiving the shared addresses. For example, the other terminals may be terminals connected to the terminal, or may be other terminals in the predetermined equipment corresponding to the terminal. The number of the other terminals is at least one . 25 Further, the predetermined equipment can cache the shared addresses of the shared address set, in order to send the cached shared addresses to subsequently joined other terminals. Wherein the subsequently joined other terminals can be at least one. Further, the terminal may store the shared address set, in order to acquire the converted file in accordance with the stored shared address set subsequently. 30 Additionally, in the embodiment of the present invention, the server can be broken down into 10 7637693_1 (GHMatters) P102760.AU PETAK a front end server, a conversion server, and a sharing server. The front end server is used to communicate with the sharing server and the terminal. The conversion server is used to commnicate with the front end server. The sharing server is used to commnicate with the front end server and the terminal. Alternatively, in the embodiment of the present invention, the server can 5 also be broken down into the front end server and the conversion server, while the sharing server is a third-party equipment interacting with the server. Since the conversion server can interact with the front end server via predetermined accounts, the safety of the converted file can be guarantied. Referring now to FIG. 3B, therein is shown a schematic of a first application of the file 10 sharing method in one embodiment of the present invention. In FIG. 3B, a server is for example divided into a front end server, a conversion server, and a sharing server. The front-end server may receive a file sent from a terminal, and forward the file to the conversion server. The conversion server converts the file format of the file, and sends the converted files to the front end server. The front end server can upload the converted file to the sharing server, and receive a shared address 15 set feedback from the sharing server. The front end server can feedback the shared address set to the terminal. In summary, the file sharing method provided by the embodiment of the present invention can include, receiving a file from a terminal, generating a shared address set of the file, feedbacking the shared address set to the terminal, sharing the shared addresses of the shared 20 address set with other terminals. The method of the embodiment of the present invention solves the problems in the prior art of increased interactions between the server and the terminal caused by uploading the decomposed file pages to the server individually and repeatedly when the file has multiple pages, resulting in saving communication resources and reduction of the cost. In the file sharing method of the embodiment of the present invention, the server can convert 25 the file format of the file to avoid installation of an application for presenting the file. For example, when the file is a PPT file, the terminal can install only the application client or the website client of the team voice instrument to view the PPT file, instead of an OFFICE application for presenting the PPT file. Additionally, by enabling at least two system modes in parallel, the file pages of the files can 30 be converted in sequence in each of the system modes by a predetermined file format conversion 11 7637693_1 (GHMatters) P102760.AU PETAK application pre-installed on the server, and the predetermined file format conversion application can be invoked in parallel in the server to convert the files. The method of the embodiment of the present invention solves a low conversion efficiency problem caused by individual conversion of the files with the predetermined file format conversion application, resulting in improvement of 5 the conversion efficiency. Referring now to FIG. 3C, therein is shown a schematic diagram of a second application of a file sharing method. The file sharing method provided in the embodiment of the present invention can be applied in online education. In FIG. 3C, teachers can prepare a PPT lecture file on the terminal, wherein the PPT lecture file can include at least one page. The teachers send the PPT 10 lecture file to the server via the terminal. The server can convert each of the PPT lecture file pages to one of images, and generate an image set of all the images. The server can store each of the images of the image set, and assigns a URL to one or several images. The server can combine the URLs of the images into a URL set, and forward the URL set to the terminal. After receives the URL set via the terminal, the teachers can send or broadcast the URL set to 15 other terminals connected to the terminal. Alternatively, the teachers can send the URL set to a predetermined equipment, and the predetermined equipment can broadcast the URL set to students. Further, to diversify the course contents, the predetermined equipment may provide multiple teaching channels corresponding to subjects. Each of the teaching channels can be accessed by a teacher and several students. After 20 receives the URL set, the predetermined equipment can determine the teaching channel accessed by the teacher, and broadcast the URL set to the students who access the said teaching channel. The teacher through the terminal and the students through the other terminal 1, 2..., and n, send image requests with the URL to the sharing server, and download the images in accordance with the URL. Alternatively, in order to improve the success rate of sharing images, the teacher can 25 share the URLs after acquiring the images. For example, the teacher can send the requests with the image URL to the sharing server and download the images in accordance with the URLs from a sharing server, before send the URLs to the predetermined equipment. After receiving the URLs, the predetermined equipment can determine the teaching channel accessed by the teacher, and broadcast the URL to the students who access the said teaching channel. Through other terminals 30 1, 2, to n, the students can send image requests with URL to the sharing server, and acquire the 12 7637693_1 (GHMatters) P102760.AU PETAK images from the sharing server corresponding to the URLs. The teacher can teach the course based on the images, after teacher and students get all the images. Further, the predetermined equipment can store the broadcasted URL set. If the predetermined equipment detects that subsequently joined students accessing the said teaching 5 channel, the predetermined equipment can send the URL set to the subsequently joined student terminals. The subsequently joined student terminals can acquire the converted images in accordance with the received URL set. Referring now to FIG. 3D, therein is shown an application interface diagram of the file sharing method in the embodiments of the present invention. In FIG. 3D, the teacher teaches a 10 mathematics course. The teacher and the students access a teaching channel 8619. The total number of persons accessing the teaching channel is 364. The teacher's lecture content is shown in an exercise area 310 on the left of the screen. From top to bottom on the right of the screen is a teacher information display area 311, a floor control display area 312, a discussion & question display area 313, and an input display area 314. Wherein, the teacher information includes a 15 teacher's picture, a nickname, and number of followers. After the students enter texts in an input box in the input display area 314 and click a SEND button to the right of the input box, the students entered texts can be displayed in the discussion & question display area 313. Referring now to FIG. 4, therein is shown a flow chart of a file sharing method in another one embodiment of the present invention. The flow chart in FIG. 4 describes the file sharing method 20 applied to implementing environment shown in FIG. 1. The difference between this embodiment and the embodiment shown in FIG. 2 is that, the server can convert the received lecture file format, and share the converted lecture file. The file sharing method can include following steps. Step 401, the teacher terminal can send the lecture file to the server, wherein the lecture file can include at least one lecture file page. 25 The lecture file sent to the server from the teacher terminal can be the lecture file generated by the teacher terminal, or acquired from other equipment. The embodiment of the present invention does not restrict file sources. Wherein acquiring the file from other equipment can avoid installation of the application supporting the lecture file format on the teacher terminal, and save memory spaces thereof. 30 In general, one lecture file can include at least one file pages. To reduce the interaction 13 7637693_1 (GHMatters) P102760.AU PETAK between the teacher terminal and the server, the teacher terminal can send entire lecture file to the server. Further, the teacher terminal can send the server a plurality of the lecture files altogether. The teacher terminal can send the server the lecture files via a wired or wireless network. Step 402, the server receives the lecture file from the teacher terminal. The server can receive 5 the lecture file from the teacher terminal via a wired or wireless network. Step 403, the server can convert each of the lecture file pages to one of converted lecture file pages with a predetermined file format. Because the server is pre-installed a predetermined file format conversion application converting the lecture file, the server can call the predetermined file format conversion application 10 after receives the lecture file. The server then can decompose the lecture file into a plurality of lecture file pages, and convert each of the lecture file pages to one of converted lecture file pages with the predetermined file format. Wherein the predetermined file format can be default or specified, such as, an image format or a text format. The converted lecture file pages refer to the file pages of the decomposed lecture file page converted to the predetermined file format. 15 Typically, the server can enable a system mode. In the system mode, the predetermined file format conversion application can only convert one lecture file at a time, resulting in a lower lecture file conversion efficiency. Wherein, the system mode may be system user accounts. Therefore, if there are at least two lecture files, the lecture file format conversion may include: enabling at least two system modes in parallel, and 20 converting each of the lecture files in sequence in each of the system modes with the predetermined file format conversion application pre-installed on the server. For example, when WINDOWS system is installed in the server, the WINDOWS system can set up at least two user accounts. Since each of the user accounts can call OFFICE to convert one PPT lecture file, parallel logging on to the at least two user accounts can convert at least two PPT 25 lecture files in parallel, resulting in improvement of the conversion efficiency. The version of the predetermined file format conversion application installed on the teacher terminal may be viarious. Different version of the predetermined file format conversion application may convert the lecture file differently. For example, a lower version of the predetermined file format conversion application may convert the lecture file with a lower 30 conversion quality. Therefore, the server can install the latest version of the predetermined file 14 7637693_1 (GHMatters) P102760.AU PETAK format conversion application and convert the lecture file with the latest version to avoid lower conversion quality and conversion inconsistency resulting from conversion of the lecture file by different teacher terminals. Further, the server can configure conversion parameters of the predetermined file format 5 conversion application, to further improve the lecture file conversion quality. Specifically, before enabling at least two system modes in parallel, the conversion parameters for the predetermined file format conversion application are configured. Then, converting the lecture files in sequence via the predetermined file format conversion application installed on the server comprises converting the lecture files in sequence through the predetermined file format conversion 10 application after configuration. For example, OFFICE can configure an image resolution when converting a PPT lecture file to an image. The server can configure the image resolution in accordance with the conversion requirement. Step 404, the server can share each of the converted lecture file pages and generate the 15 shared address set of the converted lecture file. Wherein the shared address set includes at least one shared address, and each shared address corresponds to at least one converted lecture file page. The server can generate a shared address for each of the converted lecture file pages. The teacher terminal can acquire a single converted lecture file page in accordance with one of the 20 shared addresses. Or the server can generate one shared address for at least two converted lecture file pages. The teacher terminal can acquire at least two converted lecture file pages in accordance with a single shared address, to reduce the interaction between the teacher terminal and the server, resulting in improvement of the downloading efficiency. After generates the shared addresses of the lecture file pages, the server can combine the 25 shared addresses of all lecture file pages into the shared address set and send the shared address set to the teacher terminal, to save the communication resources required by sending the shared addresses to the terminal individually and repeatedly. Step 405, the server feedback the shared address set to the teacher terminal.

Referring now to FIG. 5, therein is shown a flow chart of a file sharing method in another one embodiment of the present invention. The flow chart in FIG. 5 describes the file sharing method applied to the implementing envrionment shown in FIG. 1. The difference between the current 10 embodiment and the embodiment shown in FIG. 4 is that, the server can be broken down into a front end server, a conversion server, and a sharing server. The file sharing method can include following steps. Step 501, the teacher terminal send the lecture file to the front end server, wherein the lecture file can includes at least one lecture file page. 15 The lecture file sent to the server from the teacher terminal can be the lecture file generated by the teacher terminal, or acquired from other equipment. The embodiment of the present invention does not restrict to file sources. Wherein acquiring the file from other equipment can avoid installation of the application supporting the lecture file format on the teacher terminal, and save memory spaces of the teacher terminal. 20 In general, the lecture file can include at least one lecture file pages. To reduce the interaction between the teacher terminal and the front end server, the teacher terminal can send entire lecture file to the front end server. Further, the teacher terminal can send the front end server a plurality of the lecture files altogether.

Step 503, the front end server can send the lecture file to the conversion server. Wherein, the conversion server can convert the format of each of lecture file pages in the 30 lecture file. 18 7637693_1 (GHMatters) P102760.AU PETAK Step 504, the conversion server receives the lecture file from the front end server, and converts each lecture file page of the lecture file to the converted lecture file page with the predetermined file format. Because the conversion server is pre-installed a predetermined file format conversion 5 application, the conversion server can call the predetermined file format conversion application after receives the lecture file. The lecture file can be decomposed into lecture file pages by the predetermined file format conversion application, and each of the lecture file pages can be converted to the converted lecture file pages with a predetermined file format. The predetermined file format can be a default or a specified file format, such as an image format or a text format. 10 The converted lecture file pages can refer to the decomposed lecture file pages subjected to the predetermined file format conversion. Typically, the conversion server can enable a system mode. In one system mode, the predetermined file format conversion application can only convert one lecture file at a time, resulting in a lower lecture file conversion efficiency. The system mode may be system user 15 accounts. Therefore, if there are at least two lecture files, the lecture file format conversion may include: enabling at least two system modes in parallel, and converting each of the lecture files in each of the system modes with the predetermined file format conversion application pre-installed on the conversion server. For example, when the conversion server installs WINDOWS system, at least two user 20 accounts can be set up in the WINDOWS system. Since each of the user accounts can call OFFICE to convert one PPT lecture file, parallel logging on to the at least two user accounts can convert at least two PPT lecture files in parallel, resulting in improvement of the conversion efficiency. The version of the predetermined file format conversion application installed on the 25 teacher terminal may be viarious. Different version of the predetermined file format conversion application may convert the lecture file differently. For example, a lower version of the predetermined file format conversion application may convert the lecture file with a lower conversion quality. Therefore, the conversion server can install the latest version of the predetermined file format conversion application and convert the lecture file with the latest 30 version to avoid lower conversion quality and conversion inconsistency resulting from convertion 19 7637693_1 (GHMatters) P102760.AU PETAK of lecture files by different teacher terminals. Further, the conversion server can configure conversion parameters of the predetermined file format conversion application, to further improve the lecture file conversion quality.

Then converting the lecture files via the predetermined file format conversion application installed in the conversion server including converting the lecture files via the predetermined file format conversion application after configuration. For example, OFFICE can configure an image resolution when converting a PPT lecture file 10 to an image. The conversion server can configure the image resolution in accordance with the conversion requirement. Step 505, the conversion server sends the converted lecture file pages with the predetermined file format to the front end server. The conversion server can convert each of the lecture file pages to one of the converted 15 lecture file pages with the predetermined file format, and send the converted lecture file pages to the front end server. Step 506, the front end server receives the converted lecture file pages with the predetermined file format. Step 507, the front end server sends the converted lecture file pages with the predetermined 20 file format to the sharing server. Wherein, the sharing server can share the converted lecture file pages with the predetermined file format. Step 508, the sharing server shares each of the converted lecture file pages with the predetermined file format, generates a shared address set of the converted lecture file pages. 25 Wherein the shared address set can include at least one shared address, and each shared address corresponds to one of the converted lecture file pages. The sharing server can generate a shared address for each of the pages of the converted lecture file. The teacher terminal can acquire a single converted lecture file page in accordance with one the shared address. Or the sharing server can generate a shared address for at least two 30 converted lecture file pages. The teacher terminal can acquire at least two converted lecture file 20 7637693_1 (GHMatters) P102760.AU PETAK pages in accordance with a single shared address, to reduce the interaction between the teacher terminal and the sharing server, resulting in improvement of the downloading efficiency. Step 509, the sharing server can send the shared address set to the front end server. After generates the shared addresses of the lecture file pages, the sharing server can combine 5 the shared addresses of all lecture file pages into the shared address set and send the shared address set to the front end server, to save the communication resources required from sending the shared addresses individually and repeatedly. Step 510, the front end server receives the shared address set. Step 511, the front end server feedback the shared address set to the teacher terminal. 10 The front end server can send the shared address set to the teacher terminal, to save the communication resources required from sending the shared addresses individually and repeatedly. Specifically, the front end server can feedback the shared address set via a wired or wireless network. Step 512, the teacher terminal receives the shared address set from the front end server. 15 Specifically, corresponding to the manner of sending the shared address set by the front end server, the teacher terminal can feedback the shared address set via a wired or wireless network. Step 513, the teacher terminal can acquire the lecture file page corresponding to each shared addresses of the shared address set. If the teacher terminal needs to acquire the converted lecture file, the teacher terminal can 20 acquire the converted lecture file from the sharing server in accordance with the shared address set received from the sharing server. For example, the teacher terminal can acquire the lecture file pages in accordance with the shared addresses of the shared address set in sequence. Or, the teacher terminal may acquire a plurality of lecture file pages in parallel in accordance with a plurality of shared addresses of the shared address set. 25 Step 514, the teacher terminal shares the shared addresses of the shared address set with the student terminals, after acquires the converted lecture file pages corresponding to the shared addresses.
