It should be noted that the teaching terminal processes the courseware local to the teaching terminal according to the operation, and other listening terminals process the courseware local to the other terminal according to the operation.

Example two

Fig. 5 is a flowchart of a method for operating a courseware according to the second embodiment of the present invention. This embodiment is based on the foregoing embodiment and adds processing operations of synchronizing multimedia data and verifying operation rights. The method may include the following steps:

S501. Display the interface between the lectures.

Among them, the lecture room is logged in with the lecture terminal and other lecture terminals, the lecture terminal has uploaded the courseware to the lecture room, and the other lecture terminals have downloaded and displayed the courseware.

S502. Download the courseware, and display the courseware in the interface of the classroom.

S503: Play multimedia data from the lecture terminal and/or the other lecture terminal.

S504. Collect multimedia data.

S505. Synchronize the multimedia data to the teaching terminal and the other listening terminals.

In the course of teaching, there are usually questions and answers and other links. The user as the instructor will explain and ask questions about the courseware, and the user as the listener will answer and ask questions about the courseware. For this reason, in this embodiment, the teaching terminal and the lecture The multimedia data is synchronized between the terminals, so that a two-way interaction is formed between the user as the lecturer and the user as the lecturer.

The so-called synchronization means that the current lecture terminal receives and plays multimedia data from the teaching terminal and/or other lecture terminals, and both the lecture terminal and other lecture terminals receive and play the multimedia data from the current lecture terminal.

For lectures, multimedia data can be audio data, that is, the user as the instructor and the user as the listener interact through voice, or the multimedia data can contain both video data and audio data, that is, the user as the instructor Interact with users who are lecturers through voice and screen.

It should be noted that, in order to achieve the effect of live broadcast, the multimedia data may have a streaming structure.

On the one hand, audio data is mostly raw data such as PCM (Pulse Code Modulation), and the encoder can be called to encode the audio data into a specified audio format, such as AAC (Advanced Audio Coding, advanced audio coding).

On the other hand, the video data is mostly YUV (Y represents brightness (Luminance, Luma), U represents chrominance (Chrominance), V represents density (Chroma)) and other raw data, and the encoder can be called to encode the video data into a specified Video format, such as H.264 (digital video compression format), etc.

After that, the packer can be called to encapsulate the audio data in the specified audio format and the video data in the specified video format into multimedia data in the specified stream format, such as MP4 (Moving Picture Experts Group 4, the fourth edition of the Moving Picture Experts Group), FLV ( Flash Video, streaming media format) and so on.

In this embodiment, RTSP (Real Time Streaming Protocol), RTMP (Real Time Messaging Protocol), HLS (HTTP Live Streaming, based on HTTP (Hyper Text Transport Protocol, the streaming media transmission protocol of Hypertext Transport Protocol) and other protocols transmit multimedia data.

In implementation, for the teaching terminal and/or other listening terminals, the teaching terminal and/or other listening terminals are equipped with a microphone, and the microphone can be used to collect the user who is the lecturer and/or the user who is the lecturer for the courseware. Sound, generate audio data, send the audio data to the server, and send the audio data from the server to the current lecture terminal.

Alternatively, the teaching terminal and/or other listening terminals are equipped with a microphone and a camera, and the microphone can be used to collect the sound of the user as the instructor and/or the user as the listener for the courseware to generate audio data, and the camera can be used to collect as The user of the lecturer and/or the user who is the lecturer generates video data for the screen of the courseware, and sends the audio data and the video data to the server, and the current listening terminal receives the audio data and the video data from the server.

After the current listening terminal receives multimedia data from the teaching terminal and/or other listening terminals, it can detect whether the current listening terminal is connected to an expansion device through HDMI (High Definition Multimedia Interface) interfaces, etc., the expansion device Also known as auxiliary equipment, it is used to enhance the functions of the current lecture terminal, such as auxiliary display screens, etc. The extended equipment can be the same type as the lecture terminal or different from the lecture terminal.

For example, if the lecture terminal is a smart interactive tablet, the extension device may be a smart interactive tablet, or a personal computer, etc.

If the current lecture terminal has been connected to an extension device, the multimedia data from the teaching terminal and/or other lecture terminals can be transmitted to the extension device, and the multimedia data can be played on the extension device.

Wherein, if the multimedia data has video data, the video data can be displayed in full screen.

At the same time, the current listening terminal keeps displaying the courseware and the tools of the courseware.

If the current listening terminal is not connected to the expansion device, the multimedia data can be played on the current listening terminal.

Wherein, if the multimedia data has video data, the video data can be maximized. At the same time, the current lecture terminal displays the tools of the courseware on top.

For the current listening terminal, the current listening terminal is equipped with a microphone, which can be used to collect the sound of the user as the listener for the courseware, generate audio data, send the audio data to the server, and the server sends the audio data to the teaching terminal And/or other listening terminal.

Alternatively, the current lecture terminal is equipped with a microphone and a camera, and the microphone can be used to collect the sound made by the user as the lecturer on the courseware to generate audio data, and the camera can be used to collect the user as the lecturer on the screen of the courseware to generate video data, The audio data and video data are sent to the server, and the server sends the audio data and video data to the lecture terminal and/or other lecture terminals.

In some embodiments, if the current lecture terminal does not have the permission to speak, as shown in Figure 4B, the current lecture terminal applies to the lecture terminal to speak through the server. When the lecture terminal receives the application, it displays the corresponding application in the lecture room. Information, if the teaching terminal clicks the "Accept" control in the application information, the application information will be cancelled and the application for the speech will be confirmed. At this time, the lecture terminal can collect multimedia data; if the teaching terminal clicks the "Reject" in the application information "Control, cancel the application information and confirm the rejection of the application to speak. At this time, the terminal is prohibited from collecting multimedia data; of course, within a certain period of time (such as 1 minute), the terminal does not click the "accept" control or "reject" ”Control, the application information is cancelled, and the application to speak is rejected. At this time, the listening terminal is prohibited from collecting multimedia data.

In this embodiment, the multimedia data of the current listening terminal can be synchronized to the teaching terminal and other listening terminals, and the multimedia data of the teaching terminal and/or other listening terminals can also be synchronized to the current listening terminal, so that multiple parties can interact through multimedia data as a medium . Classroom teaching pays more attention to the participation of students and enhances interaction, which can improve the quality of classroom teaching.

In addition, if the extension device is connected to the lecture terminal, the multimedia data from the teaching terminal and/or other lecture terminals will be played on the extension device, and the courseware and multimedia data will be displayed on different devices to maintain sufficient space for the courseware and multimedia data. Display to ensure the clarity of courseware and multimedia data.

S506: Receive an operation acting on the courseware.

S507: Determine the authority of the lecture terminal to perform the operation.

When an operation acting on the courseware is received, it can be verified whether the current listening terminal has the authority to perform the operation.

In this embodiment, the permissions include:

1. User role operation permissions

In this embodiment, the authority of the user (represented by the user account) can be managed based on RBAC.

The lecture terminal is logged in with a user account, the user account is associated with a user role, and the user role is associated with permissions.

If the user role is not configured to perform operations, the terminal does not have the user role operation permissions to perform operations;

If the user role has been configured to perform operations, the lecture terminal has the user role operation permissions to perform operations.

In the implementation, the association relationship between the user account and the user role, and the association relationship between the user role and the authority are issued by the server to the lecture terminal when the user account is logged in to the lecture terminal.

Therefore, when an operation acting on the courseware is received, the user account logged in to the lecture terminal can be determined locally at the lecture terminal, the user role associated with the user account, the authority associated with the user role, and the operation type of the operation , Operation object.

Among them, the operation object refers to the object to be operated in the courseware, including pages, elements in the pages, tools, and so on.

For pages, the types of operations can include flip, add, delete, etc.

For elements, the types of operations can include rotate, drag, zoom, and so on.

For tools, the types of operations can include add, delete, and so on.

Compare the permissions associated with the user role with the operation object and the operation type.

If the user role is not configured with the permission to perform the operation type for the operation object, it can be determined that the lecture terminal does not have the user role operation permission to perform the operation.

If the user role has been configured to perform the operation type permission for the operation object, it can be determined that the lecture terminal has the user role operation permission for performing the operation.

Of course, in addition to checking the user role operation authority locally on the lecture terminal, you can also check the user role operation authority on the server, that is, determine the user account logged in the lecture terminal, determine the operation type and operation object of the operation, and set the user account , The operation type and operation object are sent to the server. The server determines the user role associated with the user account, determines the permissions associated with the user role, compares the permissions associated with the user role with the operation object and the operation type, and compares The result is sent to the lecture terminal.

2. Operation priority permissions

In this embodiment, at the same time when the current lecture terminal performs an operation on the courseware, the lecture terminal and/or other lecture terminals have already performed other operations that act on the courseware.

The current operation may conflict with other operations. Therefore, the current operation can be compared with other operations.

If the operation conflicts with other operations, the lecture terminal does not have the operation priority authority to perform the operation.

If the operation does not conflict with other operations, the lecture terminal has the operation priority authority to perform the operation.

In some embodiments, a conflict rule may be preset, and the conflict rule is used to indicate that there is a conflict between at least two operations.

In an example of conflicting rules, if the current operation and other operations are both used to operate the same element in the courseware, the current operation conflicts with other operations.

In this example, multiple users are prohibited from continuously operating the same element in the courseware, for example, multiple users are prohibited from dragging the same element in different directions, and multiple users are prohibited from continuously zooming the same element at different zoom ratios. Element, prohibit multiple users from continuously rotating the same element according to different angles, etc.

In another example of conflicting rules, if the current operation and other operations are both used to add or delete annotation information on the courseware, the current operation conflicts with other operations.

In this example, multiple users are prohibited from adding and deleting annotation information at the same time, so as to prevent the annotation information added by one user from being deleted by other users.

In another example of conflict rules, if the current operation is used to operate a page in the courseware, the current operation conflicts with other operations.

In this example, the operations that act on the courseware page, such as turning pages, adding pages, etc., conflict with other operations.

Of course, the above conflict rules are only examples. When implementing this embodiment, other conflict rules can be set according to actual conditions such as courseware and business requirements, and the conflict rules can be added, deleted, or modified in different versions, for example, in In some cases, it is also possible to allow multiple users to continuously operate the same element in the courseware, that is, if the current operation and other operations are used to operate the same element in the courseware, the current operation does not conflict with other operations, such as Allow multiple users to continuously drag and rotate the same element in the courseware; for example, allow the operation of the courseware page and the operation of playing animation to be performed at the same time, and so on. In addition, in addition to the aforementioned conflict rules, those skilled in the art can also adopt other conflict rules according to actual needs such as courseware and business requirements.

In the implementation, the user account, the type of operation, and the object of the operation logged in at the lecture terminal are determined, and the user account, the type of operation, and the object of operation are sent to the server.

The server is used to determine whether the current operation conflicts with other operations according to the operation type and the operation object in the lecture room where the user account is located, so as to verify whether the lecture terminal has the operation priority authority to execute the current operation.

That is, the server may send to the lecture terminal the result that the lecture terminal has the operation priority authority to perform the current operation or the lecture terminal does not have the operation priority authority to perform the current operation.

In this embodiment, multiple operations that act on the courseware at the same time are verified whether they are in conflict, and conflicting operations are rejected, which can ensure the normal and orderly operation of the courseware, ensure the order of classroom teaching, and thus ensure the quality of classroom teaching.

S508: Process the courseware according to the operation.

If it is verified that the current listening terminal has the authority to perform the operation, the courseware is allowed to be processed according to the operation.

If it is verified that the current listening terminal does not have the authority to perform the operation, it is forbidden to process the courseware according to the operation, and a prompt message is displayed, which is used to prompt that the operation is prohibited.

In a processing method, after it is determined that the listening terminal has the authority to perform operations, the pages in the courseware are processed according to the operations, the processing results are obtained, and the processing results are displayed on the courseware.

For example, for an operation that acts on a page of a courseware, if it is determined that the listening terminal has the authority to perform the operation, the page in the courseware will be processed according to the operation, such as turning pages, adding pages, etc.

In another processing method, the pages in the courseware are processed according to the operation to obtain the processing result; if it is determined that the listening terminal has the authority to perform the operation, the processing result is displayed on the courseware; if it is determined that the listening terminal is capable of performing the operation , Delete the processing result.

For example, for the annotation information, the annotation information can be generated according to this operation, and the annotation information is loaded into the memory and will not be displayed on the user interface temporarily.

If it is determined that the listening terminal has the authority to perform operations, the annotation information will be displayed on the courseware.

If it is determined that the listening terminal has the authority to perform the operation, the annotation information will be deleted.

In this embodiment, because the courseware is processed in advance, the processing result can be displayed immediately after the terminal is determined to have the authority to perform the operation, and the processing time can be saved after the authority is determined to perform the operation, thereby speeding up the operation The response speed.

In another processing method, the page in the courseware can be processed according to the operation, and the result of the processing can be displayed in the courseware. After confirming that the current listening terminal has the authority to perform the operation, the result of the processing can be maintained. After the current lecture terminal does not have the authority to perform the operation, the result of the processing is cancelled.

S509. Synchronize the operation to the teaching terminal and the other listening terminals.

In implementation, the current lecture terminal determines the user account logged in to the lecture terminal, the operation type, operation object, and operation parameters of the operation.

The so-called operating parameters can refer to the information used to perform the operation, for example, whether it can be selected during frame selection, whether the aspect ratio is fixed when zooming, whether to display border lines, whether to zoom in or out, whether to display the selection box, whether to enable the delete function , Whether to enable the top function, whether to enable the clone function, whether to enable the rotation function, whether to set the border color, whether to set the fill color, whether to enable the 3D rotation function, original position, etc.

The user account, operation type, operation object, and operation parameters are sent to the server as instructions. The server is used to send the operation type, operation object and operation parameters as instructions to the teaching terminal and other lectures in the classroom where the user account is located. terminal.

The teaching terminal and other listening terminals are used to process the operation object according to the operation type and operation parameters, obtain the processing result, and display the processing result on the courseware.

In this embodiment, the current listening terminal sets a sending buffer area in the buffer, which can buffer the instructions generated by the current listening terminal, and use the instructions to characterize the operation acting on the courseware.

Therefore, operations can be written into the preset sending buffer area, and all operations in the sending buffer area are synchronized to the teaching terminal and other listening terminals at a preset time interval, that is, the sending buffer area will be sent every preset time interval All the instructions generated for the operation in are sent to the server, and the server sends the instructions to the teaching terminal and other listening terminals.

Generally, the value of this time is set to be small, such as 10ms, which can ensure the real-time operation.

During the buffer operation, the current operation can be compared with other operations in the sending buffer area.

If the current operation is the same as other operations in the sending buffer area, the operation is repeated, and the current operation or other operations can be filtered out.

or,

If the current operation covers other operations in the send buffer, the other operations are invalid relative to the current operation, and other operations can be filtered out.

For example, other operations in the sending cache drag an element from position A to position B, and the current operation drags the element from position B to position C, that is, for this element, the final position is position C , Then position B is invalid.

In this embodiment, by caching operations in the sending buffer area, it is convenient to compare operations, filtering out the same operations and overlapping operations, thereby filtering out invalid operations and reducing the number of operations in the sending buffer area, thereby Reduce the amount of data transmitted and reduce bandwidth usage.

In this embodiment, the verification operation authority is separated from the synchronization operation. On the one hand, the server can separate the lock service used to verify the operation authority and the instruction service used for the synchronization operation, reducing the difference between the lock service and the instruction service. Coupling facilitates the development and maintenance of the lock service and the instruction service; on the other hand, the lock service can reject conflicting operations, thereby reducing the operation of the instruction service management and reducing the load of the instruction service.
