- 在这里详述"RealClass".
- Real Class System is a distance education (or distance learning) system. Distance education
also known as distance learning , is a method of instruction and learning designed to overcome
barriers of time and space by allowing students to study in their own homes or at local facilities,
often at their own convenience, using materials available electronically or by mail. Contact
with the instructor usually occurs via telephone or e-mail. Telecommunication networks and
teleconferencing have facilitated distance learning. Libraries are working to support distance
learning by providing online catalogs and databases, electronic reserves, electronic reference
service, online tutorials, and electronic document delivery.

  The Real Class System consists of four modules which are the Real Class Center, the Data
Transmit Unit, the Teacher Client and the Student Client. Through the combined use of the
four modules, it achieves the distance learning function. The four modules' introductions
are:
  
-     * Real Class Center : It is the total control center in the Real Class System.
+     * '''Real Class Center''' : It is the total control center in the Real Class System.
-     * Data Transmit Unit: DTU (Data Transmit Unit) is transparent to teacher and student
clients
+     * '''Data Transmit Unit''': '''DTU''' ('''Data Transmit Unit''') is transparent to teacher
and student clients
-     * Teacher Client: It is the teacher's console, and provides real-time video, audio,
text and electronic lesson plans what the teacher is teaching on the screen to students.
+     * '''Teacher Client''': It is the teacher's console, and provides real-time video, audio,
text and electronic lesson plans what the teacher is teaching on the screen to students.
-     * Student Client: Student client can join a class and take part in real time communication
with the teacher in different network or different place.

time communication with the teacher in different network or different place.

- Based on Linux+NC platform and open source technology, Real Class System uses IP Network
as platform of transmission.

  Function of the system:
  
-     * Multimedia Classroom: synchronously live broadcast and share of teaching scene

and students in the way of text and audio/video stream
+     * '''Real Time Multimedia Interaction''': offer real-time the interaction between teachers

-     * Scenic On-line Stream Media Courseware Recording: teacher scenes and contents of the
class are recorded and can be used on VOD systems
+     * '''Scenic On-line Stream Media Courseware Recording''': teacher scenes and contents
of the class are recorded and can be used on '''VOD''' systems
  
- The system can transmits multimedia data adaptively according to condition of network, and
has clear, simple interface. Real Class System has independent copyright without supporting
of the third-party software, and can completely satisfy the request of real time interactive
teaching. The final aim is to share the teaching resource. The network model is showed in
