Interactive multimedia demonstration system based on electronic white board and realization method thereof

The invention discloses an interactive multimedia demonstration system based on an electronic white board, which belongs to the technical field of information demonstration and communication and mainly solves the problems of simple structure and difficulty in meeting the use demands of the electronic white board in the prior art. The interactive multimedia demonstration system comprises a user side and a client side, wherein each of the user side and the client side which have the same structures comprises a CPU (Central Processing Unit), an electronic white board functional unit, a local caching module and an input device; the electronic white board functional unit, the local caching module and the input device are respectively connected with the CPU; and the local caching module of the user side is also connected with the local caching module of the client side by a network. The invention also discloses a method for realizing the interactive multimedia demonstration system. Through hardware and software combination, the data transmission quantity of a network is reduced, the transmission efficiency is increased, double-way demonstration and communication of text information are realized, and information communication means between users at both sides are largely enriched.
