Detailed Description
The embodiment of the application provides a teleconference annotation method which is used for displaying annotation contents in a teleconference.
In the prior art, a teleconference, that is, an audio/video conference, is a conference initiated by an initiator through an initiator terminal, and a server performs communication connection between the conference initiator terminal and a conference participant terminal, so that the conference participant terminal and the conference initiator terminal establish continuous communication connection.
The method comprises the steps that screen content shared by an initiator terminal is obtained based on the initiator terminal, the screen content of the initiator terminal is transmitted to conference participant terminals through a server, all operations of the initiator at the terminals of the initiator terminal can be synchronously watched by other participants, namely when the initiator annotates a document on a shared screen of the initiator terminal, the other participants only can watch an annotation process of the initiator and cannot annotate the document. For the remote conference of which the initiator terminal and the participant terminals synchronously view the shared document, the initiator terminal can only perform page change operation on the specified page of the shared document, so that the terminals of all participants of the conference play the content of the specified page.
Therefore, in the prior art, the initiator terminal and the participant terminal cannot input annotation content to the shared document and display the annotation content to other terminals in the teleconference.
Based on the above, please refer to fig. 1, where fig. 1 describes operations of a server side in an interaction process between the server and a host terminal, an annotator terminal and other terminals about annotation contents under a teleconference connection between the server and a plurality of terminals, and the operations include:
101. receiving an annotation person identifier sent by a host terminal;
because the server and the original vehicle conference participant terminal are already in a remote conference state, the host terminal sends the annotation person identifier associated with the annotation person to the server after acquiring the annotation person determined by the host, and the server receives the annotation person identifier sent by the host terminal.
It should be noted that the number of the annotator identifiers received by the server may be multiple or one, which is determined according to the actual situation and is not limited herein.
102. Determining an annotator terminal in at least one participant terminal based on the annotation person identifier;
the server determines annotation person terminals in all participant terminals of the teleconference based on the annotation person identifiers, and the annotation person terminals are in one-to-one correspondence with the annotation person identifiers. The number of the annotator terminals corresponds to the number of the annotator identifiers, the actual number of the annotator terminals is determined according to the actual situation, and the specific situation is not limited.
103. Sending an annotation permission instruction to an annotator terminal, wherein the annotation permission instruction is used for enabling the annotator terminal to enter an annotation mode and acquiring annotation information input by a user on a target file in the annotation mode;
the server sends an annotation permission instruction to the determined annotator terminal, after the annotator terminal receives the annotation permission instruction, the annotator terminal enters an annotation mode, the annotator can annotate the target file in the annotation mode of the annotator terminal, the annotator terminal can generate annotation information based on the annotation of the annotator to the target file, and the annotation information comprises annotation content.
104. Receiving annotation information of a target file sent by an annotation person terminal, wherein the annotation information at least comprises annotation content;
after the annotation terminal generates the annotation information, the annotation terminal sends the annotation information to the server, so that the server receives the annotation information. Wherein the annotation terminal comprises a host terminal which is not permitted by the annotation permission instruction. The annotation information received by the server may be sent by a plurality of annotator terminals, or may be sent by one annotator terminal, which is determined according to the actual situation, and is not limited herein.
105. And sending the annotation information to other terminals except the annotation person terminal in the plurality of terminals, wherein the annotation information is used for enabling the other terminals to display the annotation content.
The server sends the annotation information to other terminals except the annotation person terminal in the plurality of terminals after receiving the annotation information, and the other terminals display the annotation content in the annotation information after receiving the annotation information. The server determines other terminals which do not correspond to the annotation person identifier from the plurality of terminals through the annotation person identifier.
Note that, for the server to simultaneously receive the annotation information sent by the plurality of annotator terminals, each of the plurality of annotator terminals is not only a sender sending the annotation information but also a receiver receiving the annotation information of other annotator terminals with respect to other annotator terminals of the plurality of annotator terminals. Therefore, in this embodiment, there are a plurality of terminals connected to the server in the teleconference, and there are terminals that receive only the annotation information and terminals that transmit the annotation information and that have dual identities. For the terminal with double identity, the annotation information generated by the terminal does not need to be returned to the terminal through the server, and the annotation information is sent to the rest terminals which are not the terminal through the server.
Referring to fig. 2 based on fig. 1, fig. 2 illustrates that the annotator terminal generates annotation information and displays annotation contents of other annotator terminals in an annotation mode, including:
201. receiving input operation of a user on a target file in a drawing canvas of an annotation mode;
the user, that is, the annotator, performs an input operation on the target file on the drawing canvas of the annotator terminal, where the input operation may be to input the annotation content or may be another operation associated with the input annotation content, and the annotator terminal receives the input operation of the annotator.
The other operation associated with the input annotation content may be editing of the target file, the editing function includes functions of painting brush, text editing, graphics, arrow, eraser, revocation, and the like, which are not limited herein, and the annotator may self-select a color of the annotation content to distinguish the annotation content from the annotation content of other annotator terminals.
202. And responding to the input operation, generating annotation information containing coordinate information of the target file and annotation content, wherein the coordinate information is coordinates of the annotation content in a drawing canvas, and is used for enabling at least one participant terminal to display the annotation content on the browsing canvas corresponding to the target file according to the coordinate information.
The annotation person terminal responds to the input operation and generates annotation information, the annotation information comprises annotation content and coordinate information which are mutually associated, the coordinate information is determined based on the relative position of the annotation content on a drawing canvas, and the coordinate information is used for enabling a terminal opposite to the annotation person terminal to display the annotation content on a browsing canvas associated with a target file based on the coordinate information. Because the terminal forms of the teleconference participants are different, for example, the mobile phone terminal and the computer terminal are not limited, the sizes of the drawing canvas and the browsing canvas are different, in order to correctly display the annotation content, the annotation content is often required to be correctly displayed through the size relationship between the drawing canvas and the browsing canvas, and the condition that the teleconference participants cannot normally view the annotation content in the teleconference is avoided.
204. Sending annotation information to a server;
after the annotation terminal generates the annotation information, the annotation information is sent to the server, so that the server sends the annotation information to other terminals associated with the annotation terminal, and the other terminals display the annotation content of the annotation information.
203. Receiving annotation information of a target file sent by a server;
because the annotator terminal has identity duality, the self annotation information can be sent, and the non-self annotation information can be received, so when the server sends and receives the annotation information sent by other annotator terminals to the annotator terminal, the annotator terminal receives the annotation information.
204. And displaying the annotation content of the target file.
After the annotator terminal receives the annotation information of other annotator terminals, the annotator terminal determines a target position for displaying the annotation content on a browsing canvas of the annotator terminal based on the coordinate information of the annotation information, so that the annotation content is displayed at the target position. The browsing canvas of the annotator terminal is also the drawing canvas, so that the input operation can be carried out and the annotation content of other annotator terminals can be displayed based on the same canvas.
It should be noted that, for a terminal that is not a annotator terminal, the same annotator terminal receives the annotation information of all the annotator terminals, so that how the annotator terminal processes the received annotation information can be applied to a terminal that is not a annotator terminal.
Referring to fig. 3 based on fig. 2, fig. 3 illustrates that the server processes annotation information of a target page, and during an annotation process, an annotator terminal performs an input operation on annotation content on the target page of a target file, including:
301. receiving a page number identifier sent by a host terminal, wherein the page number identifier corresponds to a target page of a target file;
after determining a target page of a target file to be played, the host terminal sends a page identifier corresponding to the target page to the server, so that the server receives the page identifier.
302. Generating a page changing instruction containing a page number identifier according to the page number identifier;
the server generates a page-changing instruction containing the page number identification based on the received page number identification.
303. Sending a page change instruction to a plurality of terminals, wherein the page change instruction is used for enabling the plurality of terminals to play a target page of a target file according to the page number identifier;
and the server sends a page change instruction to all participant terminals of the teleconference, and after all the participant terminals of the teleconference receive the page change instruction, target pages corresponding to the page identifiers in the target file are played according to the page identifiers of the page change instruction.
304. Receiving annotation information of a target page of a target file sent by an annotator terminal.
The annotation terminal can perform input operation on the annotation content on the target page, generate annotation information and then send the annotation information to the server, and the server receives the annotation information on the target page and then sends the annotation information on the target page to other terminals corresponding to the annotation terminal, so that the other terminals can display the annotation content.
Referring to fig. 4 based on fig. 3, fig. 4 illustrates the fusing of the annotation content and the target file by the server and generating the download address, including:
401. generating a fusion file in a preset format according to the page number identifier, the annotation content and the target file, wherein the target page corresponding to the page number identifier in the fusion file contains the annotation content;
after receiving the page identifier sent by the host terminal and the annotation information of the target page corresponding to the page identifier sent by the annotator terminal, the server stores the page identifier, the annotation content in the annotation information and the coordinate information, so that after the teleconference is finished, a fusion file in a preset format is generated according to the page identifier, the annotation content, the coordinate information and the target file, and the target page corresponding to the page identifier in the fusion file contains the annotation content, wherein the preset format can be a PDF format, and is not limited herein.
It should be noted that the merged file may be a merged file corresponding to a single annotator terminal, and the annotation content in the merged file corresponds to the single annotator terminal; the integrated file may also be an integrated file corresponding to a plurality of annotator terminals, the annotation content in the integrated file integrates the respective annotation content of the plurality of annotator terminals, and each annotator terminal or host terminal may select to integrate the annotation content of the terminal meeting its own requirements.
402. And generating a download address of the fusion file, wherein the download address is used for returning the download address for downloading the fusion file according to the download request if the server receives the download request of the fusion file.
