Wireless interaction electronic whiteboard conference system

Abstract

The invention provides a wireless interaction electronic whiteboard conference system. The wireless interaction electronic whiteboard conference system comprises an electronic whiteboard and user side communication equipment, wherein a point-to-point wireless network connection is realized through the electronic whiteboard and the user side communication equipment based on a p2p protocol; the electronic whiteboard is compatible with at least two wireless transmission protocol standards; the user side communication equipment automatically searches for and is connected with the electronic whiteboard according to the p2p protocol; the user side communication equipment sends a message to the electronic whiteboard after the connection; and the electronic whiteboard determines a protocol standard supported by the user side communication equipment according to a content format of the message, and calls a protocol standard which is matched with the user side communication equipment to realize wireless connection access. Through adoption of the wireless interaction electronic whiteboard conference system, real-time content sharing among a plurality of pieces of equipment can be realized in a projection-video conference system anytime and anywhere, and display content of equipment of corresponding different types can be received and directly displayed on the electronic whiteboard, so that real-time annotation and explanation can be realized, and sharing, communication and discussion of a conference become more convenient and effective.

Description

technical field [0001] The invention relates to a wireless interactive electronic whiteboard conference system, which can be applied to group companies, government department telephone conferences, video conferences, teaching and teaching in the education industry, and real-time sharing of various household electronic tools such as tablets, computers, and mobile phones. Background technique [0002] The emergence of WiFi technology has replaced the wired network, freeing computers and other equipment from the shackles of network cables. However, at present, in application scenarios such as projection and video conferencing, wired transmission (HDMI / VGA / YPbPr, etc.) still occupies a dominant position, which makes sharing information between devices extremely inconvenient. [0003] Traditional wired transmission conference systems generally use projectors and electronic whiteboards: [0004] 1. In the wired projector conference mode system, the equipment functions are single ...

AI Technical Summary

Problems solved by technology

[0004] 1. In the wired projector conference mode system, the equipment functions are single and scattered, which brings a lot of trouble to the site environment, equipment connection, debugging, use and maintenance, and is not conducive to the centralized sharing and decentralized use of information.

The projection device needs to be compatible with a variety of display interfaces, such as HDMI, VGA, DVI, DP, etc.; some devices such as mobile phones and tablets have no external display interface, and cannot display its content through projection

In addition, the projection cannot be marked, added or deleted content, explained, etc.

[0005] 2. Electronic whiteboards mainly share content by copying files such as U disks. The operation is cumbersome, and the content of the device cannot be directly shared. The efficiency is low, and it is not convenient for information sharing and decentralized use between devices.
