Description
Technical Field
The application relates to the technical field of computers, in particular to a manuscript demonstration method.
Background
With the continuous development of multimedia technology, when a speaker and an audience communicate with each other face to face, a good information synchronization effect can be achieved by synchronously demonstrating the contents on respective mobile phones. The scenes of the off-line speech are mostly explained by means of slides, and information is transmitted to audiences. However, this method requires a presentation device to play, and the required devices include a computer, a projector, a large screen, and the like. With the popularization of mobile devices and comparable computing capabilities to PC computers, it has become a common rigid requirement to complete the interpretation of face-to-face documents with mobile devices.
However, when performing document presentation in the above manner, there are often technical problems as follows:
first, the same terminal is used to demonstrate the manuscript, and the experience of watching by many people at the same time is very poor. The formal playing equipment has high requirements on hardware equipment such as a projector, a large screen and the like, and cannot meet the requirements of the ad hoc conference.
Secondly, when the same-screen manuscript demonstration is carried out across terminals, the network condition is limited, the total time delay of the acquisition, transmission and playing of the real-time video is 5-10 seconds, and the problem of unsynchronized manuscript and operation often occurs.
Disclosure of Invention

This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
Some embodiments of the present disclosure propose a manuscript presentation method to solve one or more of the technical problems mentioned in the above background section.
The embodiment of the disclosure provides a manuscript demonstration method, which comprises the following steps: establishing a first link with a first terminal; generating a demonstration identifier; sending the demonstration identification back to the first terminal, wherein the first terminal generates a demonstration code according to the demonstration identification; establishing a second link with a second terminal; receiving a demonstration request and a demonstration manuscript sent by a first terminal; sending the demonstration request and the demonstration manuscript to a second terminal; receiving a termination request sent by a first terminal; sending a termination request to the second terminal; receiving a file recording code sent by a first terminal, wherein the first terminal generates the file recording code; and pushing the file recording code to the target equipment, and controlling the target equipment to play the file recording code.
The above embodiments of the present disclosure have the following beneficial effects: through the manuscript demonstration method of some embodiments of the present disclosure, only the manuscript and the operation instruction need to be sent when the manuscript is demonstrated across terminals, the transmitted data volume is small, the requirement on the network bandwidth is low, the problem of unsynchronized manuscript and operation is solved, and the user friendliness is improved. Specifically, the inventors found that the main reasons for the poor user experience of the document presentation are: the user can hardly watch the same terminal presentation, and the problem of document and operation asynchronism occurs due to the transmission pressure that the network bandwidth can not bear videos and images when the terminal is crossed to present the same screen presentation, which finally influences the user experience. Based on this, first, some embodiments of the present disclosure generate a presentation identification for a first terminal after establishing a first link with the first terminal. Second, the presentation identification is sent back to the first terminal. And the first terminal generates a demonstration code according to the demonstration identifier, and the demonstration code is used as a basis for subsequent terminal-crossing on-screen demonstration of the manuscript. Third, a second link is established with the second terminal. The second terminal acquires the demonstration code. And fourthly, receiving a demonstration request and a demonstration manuscript sent by the first terminal. And the first terminal demonstrates the presentation according to the demonstration request. In the step, only the presentation is transmitted, and the operation instruction is generated according to the presentation request, but the video is not directly transmitted, so that the transmitted data volume is greatly reduced. And fifthly, sending the demonstration request and the demonstration manuscript to the second terminal. And the second terminal demonstrates the presentation according to the demonstration request. During this step of transmission, only the presentation is transmitted, and the operation instruction occurs according to the presentation request. And sixthly, receiving a termination request sent by the first terminal, sending the termination request to the second terminal, and ending the process of the current manuscript demonstration. And finally, receiving the file recording code sent by the first terminal. The first terminal generates a file recording code. In order to realize the same-screen presentation in the whole process of the processing mode, only the presentation and the operation instruction are transmitted through the network, and the cross-terminal presentation of the presentation is realized without transmitting videos. In the scenes of an ad hoc conference and a speech, the processing mode has very low requirements on hardware equipment and a network, and has very good experience on simultaneous watching of multiple people in the same manuscript.

And the first terminal generates a demonstration code according to the demonstration identifier. Specifically, the demonstration code may be a two-dimensional code. The two-dimensional code is a coding mode widely adopted in mobile equipment, can store rich information and can also represent more data types. The two-dimensional code is a pattern which is distributed on a plane (in two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is black and white and is alternated and records data symbol information. In coding, the concept of '0' and '1' bit stream forming the internal logic basis of computer is used, several geometric shapes corresponding to binary system are used to represent literal numerical information, and the information is automatically read by image input equipment or photoelectric scanning equipment so as to implement automatic information processing.

Wherein the presentation request includes a start link instruction. Specifically, the first terminal may perform a document conversion service. Each page of the presentation is converted into a picture, and the presentation can be presented in the form of the picture. Specifically, the first terminal may establish a communication connection with the execution body by using a long link (WebSocket) scheme. WebSocket is a protocol for full duplex communication over a single TCP connection. The WebSocket enables data exchange between the first terminal and the server to be simpler, and allows the server to actively push data to the first terminal. In the WebSocket, the first terminal and the server only need to complete one handshake, and persistent connection can be directly established between the first terminal and the server, and bidirectional data transmission is carried out. Specifically, the presentation request may be an operation instruction in Object Notation (JSON) format.
In response to the presentation request being a page turn request, the first terminal determines a latest page number. Wherein the presentation request includes the latest page number. And the first terminal plays the presentation according to the latest page number.
In response to the presentation request being a doodle request, the first terminal determines a set of drawing parameters. The drawing parameter set comprises the size of a painting brush, the color of the painting brush, a coordinate sequence and drawing time. And the first terminal plays the presentation according to the drawing parameter set.

And step 206, sending the demonstration request and the demonstration manuscript to the second terminal.
In some embodiments, the execution body transmits the presentation request and the presentation to the second terminal. And the second terminal demonstrates the demonstration manuscript according to the demonstration request.
Optionally, in response to the presentation request being an automatic play request, the second terminal presents the presentation according to the second link. Specifically, a WebSocket communication connection is established between the second terminal and the execution body. The second terminal waits for the server to send various operation instructions. Specifically, the server sends the presentation in the form of a picture to the second terminal.
And responding to the demonstration request as a page turning request, and starting demonstration of the demonstration manuscript from the latest page number position by the second terminal according to the second link. Specifically, the page turning request may be an operation instruction in Object Notation (JSON) format. The page flip request may be JSON formatted data representing the latest page number.
And responding to the demonstration request as a doodle request, and the second terminal acquires the drawing parameter set. Specifically, the drawing parameter may be in JSON format. The second terminal converts the coordinate sequence into a relative coordinate sequence. And the second terminal determines the relative brush size and the relative drawing time according to the drawing parameter set. And the second terminal plays the presentation according to the relative coordinate sequence, the relative brush size, the brush color, the relative coordinate sequence and the relative drawing time length.
Optionally, the second terminal converts the coordinate sequence into a relative coordinate sequence. The second terminal determines a coordinate sequence. Specifically, the coordinate sequence includes a width of a presentation picture of the first terminal and a length of the presentation picture of the first terminal.
The second terminal responds to satisfying the following equation:
DeviceWidth/DeviceHeight≤SlideWidth/SlideHeight，
wherein, slideWidth represents the demonstration picture width of the second terminal, slideHeight represents the demonstration picture length of the second terminal, DeviceWidth represents the demonstration picture width of the first terminal, and DeviceHeight represents the demonstration picture length of the first terminal.

The second terminal determines a combination of the relative presentation picture width and the relative presentation picture length as a relative coordinate sequence.
Optionally, the second terminal responds to satisfying the following equation:
DeviceWidth/DeviceHeight＞SlideWidth/SlideHeight，
wherein, slideWidth represents the demonstration picture width of the second terminal, slideHeight represents the demonstration picture length of the second terminal, DeviceWidth represents the demonstration picture width of the first terminal, and DeviceHeight represents the demonstration picture length of the first terminal.

The optional contents in the above step 205 and 206 are: the technical contents that the first terminal and the second terminal respectively establish the first link and the second link of the WebSocket communication connection type with the server to perform the presentation and the transmission of the operation instruction are taken as an invention point of the embodiment of the disclosure, and the technical problems that the presentation of the same-screen document is limited by network conditions when the terminal is crossed and the total time delay of the acquisition, transmission and playing of the real-time video is 5 to 10 seconds, and the document and the operation are often asynchronous are solved. ". Factors causing poor presentation effect of the same-screen file across the terminals are as follows: the problem of time delay and the like can occur when videos or images and the like are transmitted through a network, so that the effect of on-screen display is influenced. If the above factors are solved, the result of improving the demonstration effect of the same-screen manuscript can be achieved. In order to achieve the effect, the WebSocket communication connection is introduced to achieve cross-terminal communication, and meanwhile only a presentation and an operation instruction are transmitted in the communication process. First, the first terminal and the second terminal respectively establish Websocket communication connection with a server. Second, a presentation request and a presentation transmitted from the first terminal are received. The first terminal demonstrates the presentation according to the demonstration request. And thirdly, the second terminal demonstrates the demonstration manuscript according to the demonstration request. The first terminal and the second terminal transmit the presentation and the operation instruction in the graphic format to the server without directly transmitting the video. When a doodle demonstration request is processed, a drawing parameter set is determined according to the display size of the second terminal, and the mode of on-screen display in the second terminal is adjusted. In the scenes of an ad hoc conference and a speech, the processing mode has very low requirements on hardware equipment and a network, and has very good experience on simultaneous watching of multiple people of the same manuscript, so that the technical problem two is solved.
In some embodiments, the execution body receives a termination request from the first terminal. Specifically, the termination request may be in JSON format. The termination request indicates that the presentation process of the presentation is finished. And the first terminal terminates the WebSocket communication connection according to the termination request.
In some embodiments, the executing entity sends the termination request to the second terminal. And the second terminal terminates the WebSocket communication connection according to the termination request.

In some embodiments, the execution body receives a file recording code sent by the first terminal. The first terminal generates a file recording code. And the first terminal converts the recorded voice in the presentation process into a recorded text. Specifically, the first terminal may convert the recorded voice during the presentation into a recorded text using a voice recognition method. And the first terminal stores the recorded text, the presentation and the operation instruction as a file recording code.
In some embodiments, the execution body pushes the file recording code to the target device, and controls the target device to play the file recording code. The target device with the display function can be a device which is in communication connection with the execution main body and can display and play the file according to the received file recording code. For example, the execution body may display the presentation and the recorded text in the received file recording code, and may repeatedly play the recorded text and the operation instruction corresponding to the voice in the presentation displaying process. The display content can be played repeatedly as required, so that the requirement for checking by a user is met, and the convenience degree of the user is improved.
One embodiment presented in fig. 2 has the following beneficial effects: through the manuscript demonstration method of some embodiments of the present disclosure, only the manuscript and the operation instruction need to be sent when the manuscript is demonstrated across terminals, the transmitted data volume is small, the requirement on the network bandwidth is low, the problem of unsynchronized manuscript and operation is solved, and the user friendliness is improved. Specifically, the inventors found that the main reasons for the poor user experience of the document presentation are: the user can hardly watch the same terminal presentation, and the problem of document and operation asynchronism occurs due to the transmission pressure that the network bandwidth can not bear videos and images when the terminal is crossed to present the same screen presentation, which finally influences the user experience. Based on this, first, some embodiments of the present disclosure generate a presentation identification for a first terminal after establishing a first link with the first terminal. Second, the presentation identification is sent back to the first terminal. And the first terminal generates a demonstration code according to the demonstration identifier, and the demonstration code is used as a basis for subsequent terminal-crossing on-screen demonstration of the manuscript. Third, a second link is established with the second terminal. The second terminal acquires the demonstration code. And fourthly, receiving a demonstration request and a demonstration manuscript sent by the first terminal. And the first terminal demonstrates the presentation according to the demonstration request. In the step, only the presentation is transmitted, and the operation instruction is generated according to the presentation request, but the video is not directly transmitted, so that the transmitted data volume is greatly reduced. And fifthly, sending the demonstration request and the demonstration manuscript to the second terminal. And the second terminal demonstrates the presentation according to the demonstration request. During this step of transmission, only the presentation is transmitted, and the operation instruction occurs according to the presentation request. And sixthly, receiving a termination request sent by the first terminal, sending the termination request to the second terminal, and ending the process of the current manuscript demonstration. And finally, receiving the file recording code sent by the first terminal. The first terminal generates a file recording code. In order to realize the same-screen presentation in the whole process of the processing mode, only the presentation and the operation instruction are transmitted through the network, and the cross-terminal presentation of the presentation is realized without transmitting videos. In the scenes of an ad hoc conference and a speech, the processing mode has very low requirements on hardware equipment and a network, and has very good experience on simultaneous watching of multiple people in the same manuscript.
With continued reference to fig. 4, a schematic diagram of one application scenario of a document presentation method according to the present disclosure is shown.
In the application scenario of fig. 4, after the first terminal sends a request to the server, the server establishes a first link 401 with the first terminal.
