Embodiment 1

[0101] see figure 1 , showing a flow chart of steps of a data sharing method for an interactive whiteboard provided by an embodiment of the present invention. In this embodiment, the data sharing method of the interactive whiteboard can be applied to the SDK server.

[0102] Wherein, as an example, the data sharing method of the interactive whiteboard may include:

[0103] S11. Receive a whiteboard creation request and preset picture information sent by the first client, and broadcast the whiteboard creation request and the preset picture information to the second client group, so that the first client The two client groups create a second interactive whiteboard in response to the whiteboard creation request, the whiteboard creation request is generated after the first client receives the name of the first interactive whiteboard created by the user, and the preset picture information is all The first client sends the file to be displayed uploaded by the user to a preset file...

Embodiment 2

[0119] refer to figure 2 , showing a flow chart showing the steps of a data sharing method for an interactive whiteboard provided by an embodiment of the present invention. In this embodiment, the data sharing method of the interactive whiteboard can be applied to the first client. The first client terminal is respectively connected with the SDK server and the preset file server, and the second client group is connected with the SDK server and the preset file server respectively.

[0120] Wherein, as an example, the data sharing method of the interactive whiteboard may include:

[0121] S21. Acquire the whiteboard creation operation sent by the user to create the first interactive whiteboard, and receive the creation document information uploaded by the user.

[0122] The whiteboard creation operation is an interactive whiteboard creation option that the user acts on the first client. When performing the whiteboard creation operation, the user can also upload document creat...

Embodiment 3

[0153] refer to image 3 , showing a flow chart of steps of a data sharing method for an interactive whiteboard provided by an embodiment of the present invention. In this embodiment, the data sharing method of the interactive whiteboard can be applied to the second client group. The second client group is respectively connected with the SDK server and the preset file server, the SDK server is connected with the first client, and the preset file server is connected with the first client.

[0154] Wherein, as an example, the data sharing method of the interactive whiteboard may include:

[0155] S31. Receive a whiteboard creation request and preset picture information sent by the SDK server, and create a second interactive whiteboard in response to the whiteboard creation request, where the whiteboard creation request is for the first client to receive a first interactive whiteboard created by a user generated and sent to the SDK server, the preset picture information is that...

Abstract

The invention discloses a data sharing method and device of an interactive whiteboard and a communication system. The method relates to an SDK server, a first client and a second client group. The method comprises the following steps of: firstly, converting a document uploaded by the first client into picture information, and broadcasting the picture information to each client by the SDK server; making each client request a document picture with watermark information according to the picture information, create the same document whiteboard in real time and display the document picture; and meanwhile, making the SDK server broadcast the graffiti operation of a user on the document to other clients, thereby realizing that synchronous display of the operation. According to the method, multi-party document sharing and graffiti synchronous display can be realized, the problems of slow data transmission, long time delay, poor interactive experience and the like during communication of a traditional interactive whiteboard are solved, the problems of tampering, picture stealing and the like are effectively prevented by adding character watermarks to document pictures, the requirements of document sharing in the fields of finance, education and the like are met, and more convenient, safer and more efficient interaction experience is brought.

Description

technical field [0001] The present invention relates to the technical field of interactive whiteboards, and in particular, to a data sharing method, device and communication system for interactive whiteboards. Background technique [0002] Interactive whiteboard (whiteboard for short) is a high-tech product developed by a variety of high-tech means such as electronic technology and software technology. Writing traces and saving them can realize paperless office and teaching. [0003] With the rapid development of Internet technology, the demand for online communication and information sharing is increasing. In order to meet the requirements of online communication, the commonly used method is to open a document through one of the clients using the interactive whiteboard Graffiti on the document, and then use the camera to shoot the graffiti operation on the interactive whiteboard, and send the shooting video to other clients online to achieve the effect of online demonstrat...
