CU-SeeMe(tm) 0.83b1 BETA VERSION for (self-selected) Testers ONLY

CU-SeeMePPc0.83b1 and CU-SeeMe68k0.83b1 are now available. Both of
these are significant functional enhancements beyond the previous 0.80
series. Obtain by FTP to

***WARNING*** This is beta software. It has been tested through 7
alpha releases and seems quite stable, but as always, your milage may

If you pick it up and use it, you are volunteering to be a beta tester.

REFLECTOR There is also a new version of the reflector, previously
announced, 4.00, which is needed to use some of the new features of
0.83. It is on the usual anonymous ftp site,

-------- Documentation (in the same place) ----------

1. README.0.83.basic.9-8-95.txt - a consolidated readme
for Mac CU-SeeMe, as it exists in version 0.83b1, with no attempt to
detail differences from former versions.

2. README.changes.9-8-95.txt - a log of changes through the 70
series, the 80 series, the 83 alpha and, now, beta.

3. Several docs on AuxData and PlugIn's, unchanged since 0.80, still in
the 0.80 folder. PlugIn SDK is still not quite in release (waiting for
correct copyright language).

----------New In 0.83 (Highlights) ------------

1. There is a new algorithm and format for loss reports and more
communitcation with the new version of the reflector. You now have
parameters to set to limit your overall receive bw.

2. There is a participant list (Show Participant List from the Participants
Menu) which will show information about senders and lurkers and provide
control of audio, access to statistics, IP address, etc.

3. The Disconnect item in the Conference Menu now shows the IP of the other
end of your connection, either user or reflector as the case may be.

4. There is a new Audio window with level indicators for both your
mic (as before) and for incoming audio. Also there is an input gain
control to adjust the sensitivity of the mic and an output volume
control to adjust the speaker level. A dual squelch control allows
you to raise the squelch level when sound is being received from the

5. If you hold down (instead of clicking) on someone's mic icon, it
functions as a private-to-them push-to-talk. If you Option-click someones
speaker icon, instead of turning them off, it turns everyone else off.

6. Lurker windows can be opened, and you get a local window if you are a
lurker (just title bar and button bar) to give access to various controls.
In particular, a lurker can access the control panels under the local
window for audio and receive bandwidth.

7. QuickCam Audio works (yea!), although the sound is not the highest
quality. QuickCam provides 5khz sampling, and the present implementation
simply interpolates that up to 8khz so it will go thru the encoders as they
stand. Puffing up the bandwidth utilization at the sending end by 8/5ths
is clearly a sub-optimal idea, but to interoperate with everything it was
seen as a necessary mode and a starting point.
