Step S101, determining content to be transmitted; the content to be transmitted is presented based on a page with layer attributes, the content to be transmitted at least comprises first content and second content, and the first content and the second content are carried in different layers.
In some embodiments, the content to be transmitted may refer to content that is stored in a sending end and needs to be sent from the sending end to a receiving end, so as to be synchronously displayed at the receiving end.
In some embodiments, the page with the layer attribute may be a HyperText Markup Language (HTML 5) page. The different layers may refer to the base layer and the tool layer of the page, or multiple base layers of the page, or multiple sub-layers of a base layer. Wherein, the content of the tool layer and the operation aiming at the content can be synchronously displayed at the receiving end. Only part of conventional operations in the base layer can be synchronously displayed at the receiving end, and personalized operations cannot be synchronously displayed at the receiving end. The normal operation may be an operation frequently used by the user, such as a zoom operation, a highlight operation on text, and the like; when the content to be transmitted and the operation aiming at the content to be transmitted are transmitted through the basic layer, if the operation aiming at the content to be transmitted belongs to the conventional operation, the content to be transmitted and the first operation can be transmitted in the form of a data file through the basic layer. However, in the actual application process, there may be some operations that cannot be predefined, such as performing personalized operations like circle points and sketching by using irregular lines; since these personalized operations that cannot be predefined cannot be predetermined, nor can their corresponding data codes be predefined, the operations that cannot be predefined cannot be transmitted in the form of data files.
In some embodiments, the content to be transmitted may be content that needs to be presented on white boards of the teacher-side device and the student-side device in an online classroom.
Step S102, determining that the transmission mode of the first content is a first file form according to the transmission parameter of the first content.
In some embodiments, the transmission parameters of the first content may include an identification of a layer carrying the first content. And if the layer bearing the first content is the first layer and the identifier of the first layer is identified as the first identifier, determining that the transmission mode of the first content is the first file form. Wherein the first identifier is used for indicating that the first content is transmitted in the first file form.
For the case that the identifier of the first layer is the first identifier, the transmission parameter of the first content may further include a state of a layer carrying the first content. If the first layer is in an activated state, determining that the transmission mode of the first content is in the first file form; in this scenario, the first file form may be a video file form.
For the case that the identifier of the first layer is the first identifier, the transmission parameter of the first content may further include a state of a layer carrying the first content. If the first layer is in an inactive state, determining that the transmission mode of the first content is in the first file form; in this scenario, the first file form may be a data file form.
In other embodiments, the transmission parameters of the first content may include instruction parameters, which may be instruction parameters for the first content. If the identification of the first layer carrying the first content is determined not to be the first identification or the first layer is not identified, obtaining an instruction aiming at the first content; generating third content based on the first content in response to the instruction, and determining that the transmission mode of the third content is the first file form; the first content and the third content are carried in different layers, for example, the first content is carried in a first layer of a page base layer, and the third content is carried in other layers of the page above the base layer. As an example, if the first layer carrying the first content does not have the first identifier and receives an instruction for the first content, a third content is generated based on the first content, and a transmission mode of the third content is determined to be the first file form. The instruction for the first content may be a touch operation on an area on the transmitting end where the first content is displayed, such as a touch operation of clicking the area where the first content is displayed, double clicking the area where the first content is displayed, or sliding the area where the first content is displayed. In this scenario, the first file form may be a video file form.
The third content may be generated based on an operation corresponding to only the first content in the first layer of the base layer, the third content may also be generated based on the first content in the first layer of the base layer and an operation for the first content, the third content may also be generated based on an operation for all contents included in all layers of the base layer, and the third content may also be generated based on all contents included in all layers of the base layer and an operation for all contents included in the base layer.
In other embodiments, the transmission parameters of the first content may include instruction parameters, which may be instruction parameters for the first content. If the identification of the first layer carrying the first content is determined not to be the first identification or the first layer is not identified, obtaining an instruction aiming at the first content on the first layer; and directly determining that the transmission mode of the first content is the first file form in response to the instruction.
The instruction for the first content may be an instruction triggered on a display area for displaying the first content on a display interface of the sending end; the instruction may also be any instruction, where the instruction includes an identifier for indicating the first content, and the sending-end device may determine, according to the instruction, that the transmission mode of the first content is in the first file form.
Step S103, transmitting the first content based on the first file form and transmitting the second content based on a second file form, wherein the first file form is the same as or different from the second file form.

The thinking guide picture is transmitted in the form of a video file, so that the teacher-side equipment and the student-side equipment can synchronously display the thinking guide picture. Under the scene, the text in the online classroom is subjected to data coding, and a data file corresponding to the obtained text is borne on a basic layer of a page and is sent to student side equipment. Therefore, according to different contents to be transmitted, the contents to be transmitted can be coded in different modes and sent to the receiving end in different transmission modes, flexible transmission of the contents to be transmitted can be achieved, network bandwidth is saved, and the contents and the operation aiming at the contents are synchronously displayed on the two electronic devices.

The second code may be a data code, and the files in the first file form and the second file form may be data files. In the embodiment of the application, if the first layer is in an inactive state, the first content carried by the first layer is transmitted to the receiving end in the form of a data file, so that the network bandwidth is saved.
In still other embodiments, if the identity of the first layer carrying the first content is not the first identity or the first layer is not identified, and an instruction for the first content is received; generating third content based on the first content, and determining that the transmission mode of the third content is the first file form; the first content and the third content are carried in different layers, and if the first layer carrying the first content is a base layer, the layer carrying the third content may be located above the base layer. Performing first coding on the third content to obtain a file in a first file form corresponding to the third content; and transmitting a file in a first file form corresponding to the third content, so that the first content and the operation aiming at the first content at a transmitting end can be displayed at a receiving end, wherein the first file form is different from the second file form. Wherein the first encoding may be video encoding, the file in the first file form may be a video file, and the file in the second file form may be a data file. In this scenario, the first content and the operation for the first content may be displayed synchronously at the transmitting end and the receiving end of the first content.
And the display proportion of the third content on the transmitting end, which is determined based on the first content, is the same as the display proportion of the third content on the receiving end.
In the embodiment of the application, the file in the second file form may be a data file, and when the second content is transmitted in the second file form, the second content is encoded into the data file and then transmitted to the receiving end by the transmitting end, so that the network bandwidth can be saved. The file in the first file form can be a video file, and when the first content is transmitted in the first file form, the first content and the operation aiming at the first content can be synchronously displayed at a transmitting end and a receiving end of the first content; the problem that the transmitting end and the receiving end cannot synchronously display is avoided.
