Method for realizing whiteboard full-screen synchronization on web page

Abstract

The invention belongs to the technical field of networks, and particularly relates to a method for realizing whiteboard full-screen synchronization on a web page, which comprises the following steps that: a user opens the web page and loads a flash plug-in, and the flash plug-in establishes permanent connection with a Socket server and starts monitoring; when operating the web page to perform whiteboard full-screen operation, the user calls a Flash interface and transmits whiteboard full-screen state information in, and then the flash plug-in calls an application program interface (API) to transmit data to the Socket server; and a target user opens the web page and loads the flash plug-in, and the flash plug-in establishes the permanent connection with the Socket server, starts the monitoring, and when receiving the full-screen state data from the Socket server, calls a web page whiteboard full-screen processing function to perform full-screen operation processing on a whiteboard so as to realize the whiteboard full-screen synchronization. In the method, the whiteboard full-screen synchronization can be conveniently, fast and efficiently realized completely based on the web page.

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 on a web page. 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 exchanging information. 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. Text communication, audio communication, and video communication are the three most im...

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

At present, it is basically impossible to realize full-screen synchronization in Internet applications. Even if it can be realized, 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.
