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 Alpha Testers, There is a new Alpha version of CU-SeeMe, W0.70b1, w/ Audio Send and Receive available on cuseeme.cornell.edu. 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. -Rich Kennerly - PC Windows CU-SeeMe developer. ------------------------------------------------------------------------- Copyright (c) 1993, 1994, 1995, Cornell University Cornell hereby grants permission to use and copy, for any purpose, and to redistribute this binary executable version of the CU-SeeMe (tm) program (whole and unmodified), all without fee, provided that (1) any such redistribution shall realize no profit or gain, direct or indirect, (2) these copyright and permission notices, and those of Cornell's collaborators included below, appear on all copies and supporting documentation, (3) the name of Cornell not be used in advertising or publicity pertaining to distribution of the program without specific prior permission, and (4) notice be given in supporting documentation that copying and distribution is by permission of Cornell.

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'.
