Problems solved by technology

In the process of audio communication, more and more whiteboards are used for presentation documents. After the user performs a full-screen operation on the whiteboard, the demonstration area will cover the entire webpage, but the contents of the whiteboard on the other end being demonstrated will still maintain the original size. Failure to synchronize to other terminals to be demonstrated will lead to inconsistency of information at both ends, which will cause unnecessary misunderstanding and inconvenience, especially in some high-spirited occasions, if the full-screen operation of the whiteboard cannot be synchronized, it will inevitably cause unnecessary discussions and inconvenience, seriously affecting the quality and efficiency of work
[0004] Under the existing technology, it is basically impossible to realize the synchronization of the full screen of the whiteboard in the application of the Internet. Even if it can be realized, it is necessary to download and install the control, and there are certain requirements for software, hardware, costs, etc. In addition, the existing solutions The whiteboard synchronization information is passively accepted and cannot be subject to authentication control, which may cause the user's actual operation to be inconsistent with the facts, thus bringing great inconvenience to the actual operation

specific Embodiment

[0017] Such as figure 1 As shown, a specific embodiment of the present invention realizes a method for full-screen synchronization of a whiteboard, specifically comprising the following steps:

[0018] Step 101: When the source user opens the webpage, the webpage automatically loads a Flash plug-in, and the Flash plug-in establishes a permanent connection with the communication server, and starts to monitor the data transmission of the communication server.

[0019] The above-mentioned technical scheme specifically includes the following processes:

[0020] When the source user opens the webpage, the webpage automatically loads the Flash plug-in, and the Flash plug-in establishes a permanent connection with the communication server through the XMLSocket class, and starts to monitor the data transmission of the communication server.

[0021] Step 102: The Flash plug-in interface is called to transmit the full-screen status information of the whiteboard, and then the Flash ...

Embodiment 2

[0037] Such as figure 2As shown, a specific embodiment of the present invention is a system for realizing full-screen synchronization of a whiteboard, including a source user, a communication server, a synchronization storage server, and a target user, wherein: the communication server authenticates the authority of the received source user to send whiteboard full-screen status information And after the authentication is passed, the authority of the target user to receive the full-screen state information of the whiteboard is authenticated and after the authentication is passed, the communication server sends the obtained whiteboard full-screen state information to the synchronous storage server; the synchronous storage server stores and Update the full-screen status information of the whiteboard, and send the updated full-screen status information of the whiteboard to the target user and the source user.

[0038] Preferably, before the communication server authenticates the ...

Abstract

The invention discloses a method and a system for realizing white board full screen synchronization, which are applied in the technical field of networks. The method comprises the following steps that: a communication server authenticates an authority of a receiving source user to transmit white board full screen status information, and after the receiving source user passes the authentication, the communication server authenticates the authority of a target user to receive the white board full screen status information; after the target user passes the authentication, the communication server transmits the obtained white board full screen status information to a synchronous storage server; and the synchronous storage server stores and updates the white board full screen status information, and transmits the updated white board full screen status information to the target user and the source user. By the invention, white board full screen synchronization and information security can be realized under the condition of not downloading and installing software.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method and system for realizing full-screen synchronization of a whiteboard. Background technique [0002] With the rapid development of Internet technology, people can realize instant messaging activities such as chatting with friends and negotiating with partners without leaving home. Instant messaging tools that need to be downloaded and installed, such as MSN, QQ, and Netease Bubbles, have been deeply loved by everyone. These tools provide a new way for people to communicate and exchange information. Another important way of information exchange. With the help of these tools, users can realize single-person or multi-person video; can hold network video conferences; can conduct network distance education; can also greatly reduce the cost of communication between people; and improve the efficiency of communication. [0003] Currently, text communication, audio ...
