Abstract:

?To reform the traditional teaching mode， improve the quality of classroom teaching， and play the role of network， electronic classrooms have been into the classroom.The broadcast teaching is a core function which can be used as one of the key technologies to develop the network electronics classroom . By using TCP / IP protocol Winsock programming principles based on Microsoft Visual C++ 6.0 development platform， and using client / server（Client / Server） and applying the Windows socket（Winsock） API， this paper have designed and implemented the e-classroom educational broadcasting function. Through testing， it possesses better interactivity accuracy and real-time， which can satisfy the basic teaching needs.
