-----Basic Information about CU-SeeMe------------------------------------

CU-SeeMe is video conferencing software for the PC and Macintosh on the
Internet. 

***WARNING*** This is beta software.  It has been alpha tested, but we
depend on outside users to find some of the bugs for us.  If you pick up 
and use this software, you are volunteering to be a beta tester.  

CU-SeeMe, a desktop videoconferencing program, for Macintosh and PC, 
is available free from Cornell University under copyright of Cornell 
and its collaborators.  Future commercial versions and commercial 
licensing of CU-SseeMe will be available from White Pine Software, 
Cornell's Master Licensee for commercialization of CU-SeeMe.

CU-SeeMe provides a one-to-one conference, or by use of a reflector, a 
one-to-many, a several-to-several, or a several-to-many conference 
depending on user needs and hardware capabilities.  It displays 4-bit 
grayscale video windows at 160x120 pixels or at double that diameter, 
and now includes audio.  So far as we know, CU-SeeMe was the first 
software available for the Macintosh to support real-time multi-party 
videoconferencing on the Internet.

CU-SeeMe is intended to provide useful conferencing at minimal cost.
Receiving requires only a Mac with a screen capable of displaying 16 grays,
or a PC with a screen capable of displaying 256 colors, and a connection 
to the Internet.  Sending requires the same plus a camera and digitizer 
(see specs below) which can cost as little as $100 to add on.

At this time CU-SeeMe runs on the Macintosh and the PC using an IP 
network connection.  With CU-SeeMe each participant can decide to be a 
sender, a receiver, or both.  WARNING: Although being improved with 
each version, CU-SeeMe is not mature production software--USE AT YOUR 
OWN RISK.  And also, PLEASE TREAT THE INTERNET KINDLY--keep b/w limits 
set down under 100kbps, or less if you share limited bandwidth with 
others.  Many, many folks connected to the Internet can use CU-SeeMe 
with default settings and cause no problem to anyone else; but 
unfortunately, not everyone.  If you don't know whether using CU-SeeMe 
will mess up the network for someone else, CHECK IT OUT first, please.

CU-SeeMe was initially written for the Macintosh by Tim Dorcey with design
assistance and sponsorship by Richard Cogger of the Advanced Technology
group in the Network Resources division of Cornell University's Information
Technology department (CIT).  Important early contributions came from:
Cornell University Medical Colleges (CUMC), Scott Brim, and John Lynn.

The first version for Windows was written by Steve Edgar and released
in April 1994.

Since Oct.  1, 1993, the CU-SeeMe Project receives funding from the
National Science Foundation.  A very significant collaborative effort at
Cornell University Medical Colleges (CUMC) is contributing substantial
expertise and code.

Development contributers to Macintosh CU-SeeMe0.83: Cornell: Richard 
Cogger (Project Director/PI), Tim Dorcey, Scott Brim (Co-PI), John

-----How to Test CU-SeeMe------------------------------------------------

To connect for a CU-SeeMe video conference, you must have the IP address of
another CU-SeeMe user or the address of a CU-SeeMe reflector.  

You will need to use a reflector to have a multiparty conference on the
Internet.  The CU-SeeMe reflector program is a Unix program which we have
tested on a number of Unix OS's.  If you are not familiar with
IP networks, reflectors and/or your particular network set-up, ask your
system administrator for help in operating a CU-SeeMe reflector.
Instructions on how to operate a reflector follow.

As of January, 1995, Cornell regularly runs a reflector for testing 
at 132.236.91.204.  It is usually very busy.
