It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Embodiments of the present invention will be described below with reference to the accompanying drawings.
The control method for collaborative teaching provided by the embodiment of the invention is applied to a system consisting of a plurality of terminal devices, a network and a server, wherein the network is a medium for providing a communication link between the terminal devices and the server and can comprise various connection types, such as wired, wireless communication links or optical fiber cables.
The terminal equipment is divided into a teacher terminal and a student terminal according to different users, namely, the teacher user and the student user can respectively use respective terminal equipment, log in the online teaching application on the respective terminal equipment through a pre-registered account and then are connected to a server through a network to realize interaction, so that data receiving or sending and the like are performed. The terminal device may be various electronic devices having a display screen and supporting web browsing, including but not limited to a smart phone, a tablet computer, a portable computer, a desktop server, and the like.
Referring to fig. 1 in detail, fig. 1 is a flowchart of an embodiment of a control method for collaborative teaching according to the present invention.
As shown in fig. 1, the method specifically includes the following steps:
s101, determining corresponding cooperative student users and works to be cooperatively edited according to the received cooperative instructions.
In this embodiment, when a teacher user and a student user respectively perform online teaching live broadcast through online teaching applications pre-installed on their respective terminals, and when a scene requiring collaborative teaching, such as homework demonstration explanation, is involved, the teacher terminal on which the teacher user logs in for use may issue a collaboration instruction to the server, where the collaboration instruction specifies a corresponding collaboration object, where the collaboration object includes a collaborative student user and a work to be collaboratively edited, where the collaborative student user is a student user participating in collaborative editing, and the work to be collaboratively edited is a work shared and edited between the teacher terminal and the collaborative student terminal, specifically, a source terminal of the work to be collaboratively edited may be the teacher terminal or the student terminal, so as to satisfy different collaborative teaching scenes, for example, the teacher user may specify the corresponding student user to collaboratively edit the work on the teacher terminal when issuing the collaboration instruction, the teaching scene of calling and finding students to get on the desk for making questions is realized, or the teacher user can collaboratively edit the works on the appointed student terminal, so that the teaching scene of real-time correction work is realized, and the like.
The server can determine the cooperative student users designated by the current teacher user and the works to be subjected to cooperative editing when receiving the cooperative instruction, so as to perform accurate cooperative editing and data synchronization in the following process.
Specifically, the determining, according to the received collaboration instruction, the corresponding collaboration student user and the work to be collaboratively edited includes:
acquiring a cooperative student identifier and a target work identifier in a cooperative instruction when the cooperative instruction is received;
and respectively determining corresponding cooperative student users and works to be edited cooperatively according to the cooperative student identifications and the target work identifications.
In this embodiment, when determining a cooperative student user and a work to be collaboratively edited, which are specified by a current teacher user, the cooperative student identifier and the target work identifier in the collaboration instruction are identified, and each student user and the work are preset with corresponding identifiers, for example, the student users can adopt a user id or assign a unique school number, and the work can be numbered according to a preset rule (for example, user id + work distribution time), and the like, specifically, the teacher user selects a corresponding cooperative student and a target work on the teacher terminal through clicking and the like and then distributes the collaboration instruction, and then the server obtains the cooperative student identifier and the target work identifier through parsing when receiving the collaboration instruction according to the cooperative student and target work selected by the teacher user, and after correspondingly including the cooperative student identifier and the target work identifier in the collaboration instruction, and confirming the cooperative student user according to the cooperative student identification, further confirming the terminal equipment currently logged in and used by the cooperative student user, taking the terminal equipment currently logged in and used by the cooperative student user as a cooperative student terminal, and taking the works corresponding to the target work identification as the works to be cooperatively edited, so that accurate cooperative object positioning is realized, and the situations of error in cooperative editing and the like are avoided.
And S102, starting the editing authority of the teacher user or the cooperative student users on the works to be edited cooperatively.
When a teacher user issues a cooperation instruction through a teacher terminal, the teacher user enters a multi-person cooperation teaching mode, at the moment, according to the determined cooperation student users and the works to be edited cooperatively, the editing authority of the teacher user or the cooperation student users on the works to be edited cooperatively is started, and the users with the editing authority started can acquire the works to be edited cooperatively through respective terminal equipment which logs in and use and carry out real-time editing operation on the works to be edited cooperatively locally, so that efficient cooperation editing is realized.
Further, the starting of the editing authority of the teacher user or the collaborative student user on the to-be-collaboratively edited work includes:
identifying a source terminal of the works to be collaboratively edited;
and automatically starting the editing authority of the teacher user or the cooperative student users on the works to be cooperatively edited according to the source terminal and a preset authority rule.
In this embodiment, the editing permissions of the teacher user and the collaborative student users can be automatically controlled according to the preset permission rule by the source terminal of the to-be-collaboratively edited work, for example, when the source terminal of the to-be-collaboratively edited work is the teacher terminal, that is, the teacher user already has the editing permission for the to-be-collaboratively edited work, the editing permission of the to-be-collaboratively edited work by the collaborative student users is automatically opened at this time; when the source terminal of waiting to edit works in coordination is student's terminal, then be the same at source terminal and cooperation student's terminal, open automatically teacher's user is right the edit permission of editing works in coordination ensures that teacher's user can right wait to edit works in coordination freely to edit, and when source terminal is different with cooperation student's terminal, can open automatically earlier teacher's user is right the edit permission of editing works in coordination does not open cooperation student's user is to the edit permission of editing works in coordination to the condition such as work maloperation between the student user takes place for, follow-up can be opened according to the permission setting instruction that detects cooperation student's edit permission ensures the orderliness of cooperation teaching scene. Of course, the specific permissions of users other than the cooperative student user, such as browsing permission, editing permission, and the like, may also be flexibly set according to the permission setting instruction sent by the teacher user through the teacher terminal, which is not limited in this embodiment.
S103, acquiring an edited video stream of the works to be edited in a collaborative mode on a teacher terminal used by the teacher user or on a collaborative student terminal used by the collaborative student user, and correspondingly synchronizing the edited video stream to the collaborative student terminal or the teacher terminal.
After the editing authority of the corresponding user to the work to be edited collaboratively is opened, the work to be edited collaboratively is issued to the terminal equipment used by the user who has opened the editing authority through the server, that is, a teacher user or a cooperative student user who has possessed the editing authority can freely edit the work to be edited collaboratively through the teacher terminal or the cooperative student terminal respectively, optionally, the editing authority can be alternately opened according to a preset rule, for example, the editing authority of the teacher user is controlled to be opened in a first time period, the editing authority of the cooperative student user is controlled to be opened in a second time period, and the like, so that the editing video stream of the work to be edited collaboratively on the terminal equipment used by the user who currently has the editing authority is obtained in real time, and the editing video stream obtained in real time is correspondingly synchronized to the terminal equipment used by the user who currently participates in collaborative editing and does not have the editing authority, the teacher terminal and the cooperation student terminals are respectively connected with the teacher terminal and the cooperation student terminals, and the teacher terminal and the cooperation student terminals are respectively connected with the teacher terminal and the cooperation student terminals.
In the embodiment, when a scene needing collaborative teaching is performed, a complex redundant data transmission process is not needed through a work file package, the editing permission of corresponding users is directly opened after collaborative student users and works to be edited collaboratively is determined, and the works to be edited collaboratively are issued to the terminal equipment currently used by the user who has opened the editing permission according to the target work identification, so that the users with the editing permission can directly edit designated works to be edited collaboratively on respective terminals, efficient and convenient collaborative interaction is realized in the teaching process, and the data transmission and synchronization efficiency among different user terminals in online teaching is improved.
Further, after the step S103, the method further includes:
and synchronizing the edited video stream to the rest student terminals except the cooperative student terminal.
In this embodiment, the editing video stream of the works to be edited in coordination is not only synchronized between the teacher terminal participating in the collaborative editing and the collaborative student terminals, but also synchronizes the editing video stream to the remaining student terminals for displaying the editing process of the works to be edited in coordination, specifically, the remaining student terminals are all the student terminals except the collaborative student terminals in the current online teaching room, that is, when performing collaborative teaching, the real-time editing video stream of the works to be edited in coordination is synchronized to all the terminals in the current online teaching room, including the teacher terminal and the student terminals, so as to simultaneously meet the requirements of the collaborative editing and the teaching displaying.
Specifically, since the source terminals of the works to be collaboratively edited are different, the collaborative editing and synchronization can be performed in the following ways:
the source terminal of the works to be edited in a collaborative mode is a teacher terminal:
in this embodiment, the to-be-collaboratively edited work is a work generated on the teacher terminal, for example, an operation to be answered issued by a teacher user on the teacher terminal, and at this time, the editing video stream of the to-be-collaboratively edited work on the teacher terminal used by the teacher user or on a collaboration student terminal used by a collaboration student user is acquired, and the editing video stream is correspondingly synchronized to the collaboration student terminal or the teacher terminal, including:
sending the works to be edited in a collaborative mode to the collaborative student terminal;
collecting the editing pictures of the works to be edited in a collaborative mode on the collaborative student terminal and coding the editing pictures to generate a first editing video stream;
and synchronizing the first edited video stream to the teacher terminal and then decoding and playing.
The source terminal of the works to be collaboratively edited is a teacher terminal, the editing permission of the collaborating student users on the works to be collaboratively edited is automatically opened to realize the collaborating editing, and the works to be collaboratively edited are sent to the collaborating student terminals, so that the collaborating student users can directly load the works to be collaboratively edited on the collaborating student terminals logged in for use and carry out free editing operation on the works to be collaboratively edited, the picture acquisition function of the collaborating student terminals is automatically opened after the works to be collaboratively edited are loaded, specifically, the picture acquisition function starts the screen recording function on the collaborating student terminals by calling a screen recording interface to acquire the editing pictures of the works to be collaboratively edited on the collaborating student terminals in real time, and specifically, the editing pictures of the works to be collaboratively edited can be pictures of an operation area on the collaborating student terminals, the method includes that a cooperative student user carries out corresponding editing operation on a product to be cooperatively edited in an operation area on a cooperative student terminal, a first editing video stream is generated by coding the editing pictures collected in real time and then is synchronized to a teacher terminal for decoding and playing, naturally, the first editing video stream can also be synchronized to a rest student terminal for decoding and playing, the editing process of the cooperative student user on the cooperative student terminal is completely displayed to the teacher user and the rest student users in real time for watching, and specifically, the coding and decoding process of the first editing video stream can adopt an existing video coding and decoding method, which is the prior art, and is not described in detail in this embodiment.
Further, when the server receives a cooperation ending instruction, the editing permission of the cooperation student users on the works to be edited cooperatively is closed, and specifically, the cooperation ending instruction can be actively input by the teacher user on the teacher terminal so as to actively end the cooperative editing operation of the current cooperation student users; or the user of the cooperative student actively inputs the information on the cooperative student terminal to indicate that the editing operation is finished, so as to realize a teaching scene such as submission of a homework; or the output can be automatically performed according to preset collaboration time, for example, a collaboration student user is required to complete editing of a work to be collaboratively edited within specified time, and the editing right of the collaboration student user for the work to be collaboratively edited is automatically closed when the specified time is reached, so that a teaching scene of submitting homework in a limited time is realized, and an application scene of collaborative teaching is enriched.
Specifically, the interaction process between the teacher user and the student users in this embodiment is described with reference to fig. 2:
when a teacher user demonstrates works in a classroom, the demonstration video stream is sent to a student a and other students, the student a and other students watch the demonstration video stream on respective student terminals, then the teacher user can call the students to get on the desk to do questions and demonstrate the results to other students to realize cooperative teaching, for example, the teacher user issues a cooperative instruction, selects the student a to get on the desk to edit the demonstration works of the teacher user, the cooperative student user is the student a, the cooperative student terminal is the terminal used by the student a currently logging in, the works to be cooperatively edited are the demonstration works from the teacher terminal, the student a opens the editing authority and opens the browsing authority for the terminals of other students, the student a directly edits the demonstration works cooperatively on the terminal used by logging in, and sends the cooperative editing video stream to the teacher terminal and the terminals of other students, the teacher user and other students can watch the process that student a edited and demonstrated works, after student a finishes editing, then close student a's editing permission to demonstrating works, then continue to send the demonstration video stream on the teacher terminal to student a and other students this moment, continue to carry out the course explanation, have realized the teaching scene of the real-time online answer that interactive efficiency is high.
Secondly, the source terminal of the works to be edited in a collaborative mode is a student terminal, and the source terminal is the same as the collaborative student terminal:
in this embodiment, the works to be edited in coordination are works generated on a student terminal, for example, jobs edited by a certain student user on the student terminal used by the student user, and a teacher user designates the student terminal generating the works as a collaboration student terminal, at this time, the editing video stream of the works to be edited in coordination is acquired on the teacher terminal used by the teacher user or on the collaboration student terminal used by the collaboration student user, and the editing video stream is correspondingly synchronized to the collaboration student terminal or the teacher terminal, including:
sending the works to be edited in a coordinated manner to the teacher terminal;
and collecting the editing pictures of the works to be edited cooperatively on the teacher terminal and coding the editing pictures to generate a second editing video stream.
