Subject The struct of Bluesky!
Date Tue, 23 Sep 2008 01:43:15 GMT
Dear all!
        Bluesky is made up of two parts ------ Real Class System(RCS) and
MERSMP(MERSMP is a massive resources of sharing and management platform).

        The RCS. RCS is  distance education (or distance learning) system.
It is made up of four modules  -------Teacher Client, Student Client,
TServer(Real Class Center) and DTU(Date Transmit Unit).  I want to introduce
the module of Teacher to you.

         The 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. During communicating with the student,
it also can receive the real-time video and audio information from the
students. Because there are audio and video communicating function in this
module, the lib of ffmpeg is included in Teacher Client source code.
However, FFmpeg incorporates several optional modules that are covered by
the GUN GPL( So how to deal with the
license of ffmpeg or replace ffmpeg is the first and foremost problem in
Teacher Client source code.
