    • ATM (fee based dedicated line)
    • ISDN (fee based dedicated lines)

What you need to to make it happen (in the works):

  1. Group video conferencing:
  2. Individual video conferencing and individual data sharing:
  3. Group video conferencing with group data sharing:
  4. Group video conferencing with individual data sharing:

New features to implement:

  1. push_to_view.jpg (140587 bytes) A single camera system that is actually made up of 5 or 6 cameras spread throughout the room which is either voice activated or uses a "push-to-view" switch so the picture being sent from the site can change from person to person or be merged into a picture grid-- before it is transmitted off site.  Possibly the teacher could be on screen at all times and students can appear in 1/4 size screens as the teacher chooses.  See Diagram here.
  2. A TCP/IP software application that shows the teacher a list of students (whether local or remote) who are pressing the attention button (raising their hand). The teacher can select a student with the mouse and display them on screen or broadcast the students audio, data, chat, etc.
  3. A database server that all students are connected to which can store and process data from all students and re-transmit it to all students-- perhaps via a web front end.
  4. A separate monitor for (a) video and audio and (b) computer data seen by all students in all participating classrooms.  Student computer results can be quickly displayed for all students to see (both locally and remotely).
