Detailed Description

For better understanding of the technical solutions of the present invention, the following describes the embodiments of the present invention in detail with reference to fig. 1.

The utility model provides a pair of long-range interactive teaching system with synchronous blackboard writing and live function, as shown in figure 1, include: the intelligent education system comprises acamera 101, an intelligent education all-in-one machine 102, asound pickup 103 and an MCU (microprogrammed control unit)server 201, wherein thecamera 101 is connected with the intelligent education all-in-one machine 102, thesound pickup 103 is connected with the intelligent education all-in-one machine 102, and the intelligent education all-in-one machine 102 is connected with theMCU server 201.

Video signal is gathered tocamera 101, through signal connection transmission extremely wisdom education all-in-one 102, audio signal is gathered to adapter 103, through the signal line transmission extremely wisdom education all-in-one 102, wisdom education all-in-one 102 is after video signal and audio signal coding through network transmission toMCU server 201, andMCU server 201 decodes, synthesizes or superposes, encodes received audio signal decoding, audio mixing, passes back again for wisdom education all-in-one 102 through the network after the coding, simultaneously wisdom education all-in-one 102 will through the network video grade number and audio signal transmission to the internet after decoding, the interactive teaching software is equipped with in the wisdom education all-in-one 102 computer, can play the video and the audio frequency of receiving, and the interactive teaching software possesses the touch and writes the function.

On the basis of the above embodiment, in other embodiments, further, the intelligent education integrated machine 102 includes a computer and a recording and broadcasting interactive host, the computer is connected with the recording and broadcasting interactive host, and the recording and broadcasting interactive host is respectively connected with thecamera 101 and thesound pickup 103.

In this embodiment, preferably, interactive teaching software is installed in the computer of the intelligent education integrated machine 102, the received videos and audio can be played, the interactive teaching software has a touch writing function, and a teacher can send courseware or lectures to each speaker synchronously before interaction begins. In the interaction process, the teacher can write in the courseware, and the contents of the written books are forwarded to other listening and speaking parties through theMCU server 201.
