CU-SeeMe is video conferencing software for the PC and Macintosh on the
Internet. Obtain by FTP from cu-seeme.cornell.edu/pub/CU-SeeMe.
***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. Report
bugs to cu-seeme-bugs@cornell.edu.

-----New features in the latest release----------------------------------
The Latest version, W0.84, adds the following over the previous version
W0.70:
* Chat window - Lets you send and receive keyboard messages to and from
other clients. There are filters that enable you to hide text from
clients that you're not conversing with.
* QuickCam support - We now support the QuickCam parallel port camera
made by Connectix.
* Inverted Palette fixed - The inverted-looking palette that some capture
cards had (like the Promovie Spectrum and others) has been fixed. We
now support a 64 Gray palette with an 'invert' option for these cards
that will not accept the 256 Grays that CU-SeeMe used to insist upon.
* Audio fixes - The popping and clicking noises heard when there are
imperfections on the network have been much reduced. Also, when the
first packet of an audio transmission is lost, the whole transmission
is no longer ignored. A new bandwidth manager regulates outgoing
video while audio is being sent - this results in better reception.
* New version handling - The application can tell what version is running
on other client's machines (accurately) for PC or Mac, even when the
remote client is running a newer version.
Known Bugs Remaining:
* The Participants Window is slow, does not redraw correctly, sometimes
shows users in the wrong section, etc. We will have a complete replace-
ment for this Window in our next release. Please don't take time to
note specific problems in the Participants Window. The same applies
to the Toolbar under the video windows.
* Audio still is fussy about network performance especially on slower
links. This results in gaps in sound or popping and 'stuttering'.
There is still a substantial delay in the audio receive on the PC
version. Timing improvements for Audio are next on my list.

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