 Abstract

 With the spread of education in rural areasand the increasing level of farmers knowledge,
farmers enchance their awareness of science and technology in agriculture day by day, at the same
time, the demand for agricultural science and technology is becoming unprecedentedly high. In
order to settle the difficulties farmers encounter in using current rapid development of computer
technology, it is necessary to adopt the rapid development of computer technology, net technology,
especially streaming media technology to develop an on-line visualized consultation system,
which can help farmers inquiry agricultural expert by visualization and provide real-time service
for farmers.
 The system used JMF technology development tool, which integrate the multimedia processing
Java API and is an excellent platform of real-time streaming media technology. It can realize the
collection, transmission and management of the streaming media easily. Moreover, the system also
used commucation mechanism Java-Socket. With the combination of several techniques, it not
only complete the development of online system, but also realize visualization interactive inquiry
