CU-SeeMe (tm) for Windows Version 0.70b1 8/25/95
CU-SeeMe is video conferencing software for the PC and Macintosh on the
Internet.
-------------------------------------------------------------------------
To: cu-seeme-announce-l
Subject: CU-SeeMe Release w/ Audio Send & Receive, V0.70b1 available
from: Rich Kennerly <rbk1@cornell.edu>
Alpha Testers,
There is a new Alpha version of CU-SeeMe, 0.66a1, w/ Audio Send and
Receive available on cuseeme.cornell.edu in the pub/pc/misc directory.
The password is asnd: pkunzip -sasnd cuseeme
The primary new feature of this release is Audio Send capability. You can
choose to send in either 32 Kb/Sec Intel DVI or 16 Kb/Sec Delta-Mod with
50 or 100 mSec buffers. Note: There is a horrible UI bug that occurs when
you change audio transmission modes that causes most of the display to not
be re-drawn. The Toolbar and Participant Window need to be re-written to
fix a number of problems (including system resource hogging and performance
problems) but we wanted to release audio send before doing this.
There is a new audio panel, written by Steve Edgar, (who wrote
the original Windows version of CU-SeeMe more than a year ago). It
requires a DLL - IVSLIDER.DLL. Put a copy of this somewhere in your path
(preferably in /windows).
You might notice a re-drawn button for the Microphone. This now indicates
whether a participant will hear audio when you speak (it either looks like
a old-style radio microphone or has a red X through it). And, if you want
to talk to just one participant, you can hit this button to enter "Private-
Talking" mode. The speaker button button determines whether you can hear
audio from that participant.
This version does not support squelch mode. There is a PushToTalk
option that must be selected in this version. Also, we expect to have a
digital gain control for microphone sensitivity in a future release; for
now you'll have to use whatever software came with your sound card to adjust
mic gain.
We recommend using 100 mSec buffers for best performance. If you're
using a slower link (ISDN, or 28.8) you should use Delta-Mod even though
the sound quality is noticable worse; its better than dropouts.
Let us know how things work.
Known Bugs remaining:
The Control Panel for Audio doesn't refresh at all well after you select
an audio compression method or buffer size.
The Participant window takes way too long to redraw, re-draws too often,
and consumes too much system resources. The Toolbar doesn't refresh
properly.
There is still a known bug in the receive code that makes pops and clicks
when you start receiving.

Download the cuseeme.zip file in binary mode and unzip using PKUNZIP.EXE.
If you don't have a copy of the ZIP compression utilities
you can download them from ftp.cit.cornell.edu in the pub/dos/util
directory as pkz204g.exe. Then execute this file to extract the
zip utilities. ZIP is also available on lots of other public servers.
Contents of cuseeme.zip:
readme??.txt : This file.
cuseeme.txt ; General CU-SeeMe information.
cuseeme.hlp ; Hypertext Windows Help file for CU-SeeMe.
cuseeme.exe ; The CU-SeeMe program itself.
msvideo.dll ; Microsoft Video for Windows driver.
ctl3d.dll ; 3-d controls driver.
Installation:
The four cuseeme* files can go in a cuseeme directory by themselves.
msvideo.dll should go in your windows/system directory UNLESS you
have a copy of Video for Windows in which case you'll already have
a copy. (Its best not to mix versions). Also, ctl3d.dll should only
go in your /windows/system directory if you don't already have one.
You can use the Windows Program Manager to add a 'program item' for
cuseeme.exe as 'CU-SeeMeW?.????' and for cuseeme.hlp as 'CU-SeeMe Help'.
