★ ★ Application of a stand-alone terminal
|
As a kind of tool for teacher making courseware, network
teaching courseware automatic generation system can use
alone. As computer spreads wider and wider, electronic
teaching material market is increasing continually. It
is a trend that the electronic material will become a
future teaching material, because it has many advantages
of low cost, strong interactivity, lifelikeness visualization
and has vivid and colorful characteristic. Teacher can
only use a stand-alone network teaching terminal to record
the wonderful classroom teaching and make them into courseware
to communicate or to publish them as books.

in the classroom, create rich and colorful multimedia
courseware.
3. On the base of the existing multimedia classroom, only
need to add one network teaching host to create the multimedia
courseware automatic generation system. The cost for expanding
is low.
Solution function:
1. Realize picking up the screen of teacher terminal from
long distance and automatically increasing the school
courseware resource pool.
2. During the course of multimedia teaching, integrate
multimedia video and audio signals, create rich and colorful
multimedia courseware which can be directly broadcast
and be ordered on line.

★ Electrified education center
|
Electrified education center of various schools, corporations
and enterprises or television station have already had
professional video and audio technical staff and apparatus
foundation. Based on these advantages of technical staff,
technology and devices, only a small quantity of investment
is needed to realize direct broadcast, live program and
order program on line, realizing the networking function.
Solution connection graph
Solution explanation:
1. The devices of solution consist of the existing devices
of the electrified education center, network teaching
host, teacher terminal, microphone and sound mixing console,
etc.
2. Output one video and one audio signals from the existing
console of the recording and broadcasting room, and connect
them to network teaching host; meanwhile, connect the
computer which will be used during teaching or illustrating
to network teaching host through network; need not change
the existing connection mode of the electrified education
devices.
3. Video and audio signals are transmitted to network
teaching host through console, network teaching host picks
up the screen image of the teacher terminal through network.
Solution characteristics:
1. Only a small quantity of investment is needed; enable
a great many expensive existing electrified education
devices to play a role in network times; solve the problem
of how to take full advantage of the existing electric
devices in network times; adapt to the development of
modern time.
2. Need not master professional network technology; rapidly
take the advantage of the existing camera and television
technology.
3. Need not produce special software, automatically create
lots of resource on line.
4. Order program and share on line, largely extend the
applied arrange of electrified education devices.
Solution functions:
1. Directly broadcast on video and closed-circuit television,
meanwhile, directly broadcast on line and record information
on server;
