Method for realizing full-screen synchronization of whiteboard

Abstract

The invention belongs to the technical field of networks, and particularly relates to a method for realizing the full-screen synchronization of a whiteboard. The method comprises the following steps that: a user opens a webpage and loads flash, and the flash establishes permanent connection with a Socket server and starts monitoring; when operating the webpage for a whiteboard full-screen operation, the user calls a Flash interface and loads whiteboard full-screen state information, and the Flash calls an application programming interface (API) to transmit data to the Socket server; and a target user opens the webpage, loads the Flash, establishes the permanent connection with the Socket server, starts the monitoring, and calls a webpage whiteboard full-screen processing function to perform full-screen operation processing on the whiteboard, namely realize the full-screen synchronization of the whiteboard when the Flash receives the full-screen state data from the Socket server. By the method, the completely-webpage-based full-screen synchronization of the whiteboard can be realized, and the method is convenient, fast and high-efficiency.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method for realizing full-screen synchronization of a whiteboard. Background technique [0002] The development of Internet technology enables us to realize instant messaging, chat with friends, negotiate with partners, etc. without leaving home. At present, based on the instant messaging tools that need to be downloaded and installed, such as MSN, QQ, and Netease Bubbles, they have been deeply loved by everyone. It provides 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, hold online video conferences, conduct online distance education, and greatly reduce the cost of communication between people and improve efficiency. [0003] Text communication, audio communication, and video communication are the three most important...

Problems solved by technology

With the acceleration of informatization in business, education and other fields, especially after the full-screen operation of the presentation whiteboard, the demonstration area will cover the entire web page, but the content of the other whiteboards on the presentation side still maintains the original size and is not synchronized to other sites. Inconsistencies in the information at both ends caused by the demonstrated end, causing unnecessary discussions and misunderstandings

Especially in some high-serious occasions, if the full screen of the whiteboard cannot be synchronized, it will inevitably cause unnecessary discussions and seriously affect the quality and effect of the demonstration or discussion process

[0004] At present, it is basically impossible to achieve full-screen synchronization in Internet applications. Even if it can be achieved, it still needs to download and install the control, and there are certain requirements for software, hardware, costs, etc., which cannot be well popularized by the public.
