=========================================================================
3. Know issues in CVP V2.0
=========================================================================
a. If you are using Connectix VideoPhone over a Dial-up Internet connection,
you must connect to the Internet before starting Connectix VideoPhone.
Also Launcher should not be put into the Startup Group if you are using
a dial-up Internet connection.
b. You may notice some loss of audio packets on networks if you are using
a network card that has no buffering onboard (i.e. 3Com 3C509).
c. When connecting to a Connectix VideoPhone user that is connected to a
LAN and is on a Macintosh, turn off the automatic bandwidth control.
The automatic bandwidth control currently only works PC to PC.
d. When using Connectix VideoPhone to conference between and PC and a
Macintosh, be sure that you have chosen the correct audio and video
compressors. The video compressors that allow interoperability are
VIDEC(TM) and NSVideo(TM) V2.1 & V3.0.The audio compressors that allow
interoperation are None(Mac) or PCM(PC) and GSM 6.10. Also be sure that
the Macintosh has chosen 8-bit (NOT 16-bit) audio.
e. How does Connectix VideoPhone work with IBM AptivaÆs MWAVE devices (Modem
and Sound Cards) ?
The MWAVE is a DSP device that handles both the modem and sound card functions.
The problem is with the audio portion of the drivers IBM ships with the APTIVAS.
These drivers are only Full-duplex, with no option to allow you to set it to half.
Unfortunately, the MWAVE chip cannot handle both full-duplex audio and a 28.8
connection simultaneously. Other Mwave devices out there can be set to half
duplex for audio and so far that has seemed to work.
The following is the web site that contains allot of information regarding the
mwave device, in case you needed any more information: http://watson.mbb.sfu.ca/
f. Connectix VideoPhone has not been tested with "AOL WinSock", AOL's Winsock
implementation. We have had some reports that there may be some issues. Any
information with respect to this issue can be entered into Connectix VideoPhone
Bug Report form on the Connectix Web Site (www.connectix.com/connect/VPW2.html).
g. When calling someone by email address, the Calling... message in the Connectix
VideoPhone status bar will not appear, even though Connectix VideoPhone is
placing the call.
h. There is a problem with the Color Quickcam driver under Windows 3.1 on
some machines. Currently, the Color Quickcam driver for Windows 3.1 on
some systems will lock the system resources and take up all remaining RAM.
This may cause a problem with Connectix VideoPhone.
i. If you receive a GPF during or immediately following installation,
please clean out(delete the contents of) your windows temp directory and
re run the installer.
j. When using Connectix VideoPhone with a Shark MultiMedia DSVD Modem, the
best way to place a call is as follows:
1) Start your computer
2) Start Connectix VideoPhone Software
3) Place the call to the remote end with the Telephone
They should answer the phone.
4) Have the remote user start Connectix VideoPhone
5) Now complete the call through Connectix VideoPhone
by "calling" using Connectix VideoPhone
NOTE: You must first configure your Shark modem to operate in DSVD mode.
Follow these steps to configure this modem.
Windows95:
1) Open Control Panel (Start, Settings, Control Panel)
2) Double click the Modems icon.
3) Select your Shark modem and click the Properties button.
4) Select the Connection tab
5) Click on the Advanced button in the lower right.
6) Add this to the extra settings (near the bottom)
-sse=1
7) Click OK three times.
Windows 3.1
1) Start Connectix VideoPhone
2) From the menu, select Settings, Communications
3) Make sure the modem is selected, then click on the Properties button
4) Select the Advanced tab
5) Make sure to select your Shark Tiger DSVD modem
6) Click OK, then click Apply or Close
Once you have configured the software, you do not have to do this again.
Now, just follow the steps outlined above to place a DSVD conference call.
If you have trouble configuring your modem, please consult your modem
manufacturers documentation.
k. When using the AT&T Worldnet software under Windows 3.1 on machines with
8MB of RAM, you may not be able to use Netscape Navigator and Connectix
VideoPhone at the same time. This may not occur when using RamDoubler
for Windows 3.1. Contact Connectix for more information regarding
RamDoubler. See 'How to Contact Connectix' below.
l. If you install an Internet connection after installing Connectix VideoPhone,
and later configure Connectix VideoPhone Launcher to listen for internet
calls, you must quit and restart Connectix VideoPhone for the changes to
take place.
m. Windows 3.1 Only - If you are using a Dial-up internet connection, you
cannot currently listen for Connectix VideoPhone calls on both direct
modems and internet. You must select either internet or Direct modem.
Configuring Connectix VideoPhone Launcher to listen to both may cause
conflicts when using a dial-up internet connection.

4. New Features in CVP V2.0
=========================================================================
Connectix VideoPhone V2.0 for Windows
Release Notes
Connectix VideoPhone V2.0 for Windows adds a number of powerful features
focused on improved performance and ease-of-use. Connectix VideoPhone now
incorporates the User Location Service protocol which lets the user know
who is available and ready to call on the Internet. A graphical Address
Book with integrated Web browser support and direct links to Four11 is
also part of CVP V2.0 This version also supports auto negotiation of
many conference settings, including bandwidth.
a. 16-bit and 32-bit Version for Windows 3.1 and Windows95
b. Cross-Platform Capabilities with Connectix VideoPhone V2.0 for Macintosh
Connectix VideoPhone for Windows and Connectix VideoPhone for Macintosh
now interoperate over TCP/IP-based networks, such as the Internet.
c. User Location Service (ULS) Support
ULS is a protocol that dynamically, without user intervention, translates
a persons E-mail address to their IP address each time they log into the
Internet. In addition to solving the dynamic IP address problem, ULS also
enables CVP to know if a person is currently logged into the Internet
before a call is placed, therefore improving the chances that a call is
actually completed. By using ULS, CVP will also be able to randomly call
people that are known to be on the Internet.
d. User Location Service Support in Connectix VideoPhone Launcher
ULS services will be available to the CVP user, whether CVP is running or
whether launcher is running.
e. Graphical Address Book
Connectix VideoPhone's address book now has a direct link to Four11
(www.Four11.com), using the integrated web browser support in the
address book.
Connectix VideoPhone can also give the user direct access through Four11
to an individual's Personal Listing Page.
Connectix VideoPhone gives the user the ability to randomly call anyone
that is known to be on the Internet and CVP-enabled.
Connectix VideoPhone address book now stores settings for users, so each
entry can have a different connection profile.
f. Auto Bandwidth Detection and Negotiation
Connectix VideoPhone V2.0 detects the amount of bandwidth available to
the application over the communications link and automatically changes
the bandwidth the application is using to accommodate the link.
g. Drag-and-Drop File Transfer
CVP V2.0 allows drag-and-drop file transfer between the two users.
h. Text Chat
CVP V2.0 allows a text chat windows between the two users.
i. Improved User Interface
The 32-bit version of Connectix VideoPhone has an improved user interface
to take advantage of Windows95.
j. Improved Audio Quality
Connectix VideoPhone supports improved audio and video over a 28.8 Kbps
connection, either direct (modem-to-modem) or through the Internet.
=========================================================================
5. Online User's Manual
=========================================================================
The final CVP V2.0 manual is available on the Connectix Web Site (the
same place you downloaded the software). The manual is available as an
Abode Acrobat .PDF File. Adobe's Acrobat Reader Application is available
for free via Abode's WEB Site at: http://www.adobe.com/acrobat/readstep.html
=========================================================================
6. CVP V2.0 User Manual Addendum
=========================================================================
This section includes minor changes and new features to the Connectix
VideoPhone Users Manual.
Enabling and Disabling Connectix VideoPhone Launcher
----------------------------------------------------
Connectix VideoPhone Launcher can now be disabled by clicking the "Disable
Incoming Calls" Check Box in Launcher. No longer do you have to Exit
Launcher to disable incoming calls.
The Enable Video option from the Settings Menu
----------------------------------------------
This feature allows you to enable and disable the capture and compression
of video in real-time without disconnecting from the current conference. In
cases where you might be experiencing poor audio quality over the Internet,
it is recommended that you first disable your video to see if the audio
quality is improved. The audio quality may be improved either because your
computer's CPU is too slow for both audio and video or because you connection
speed is too slow for both audio and video (i.e. less than a 28.8 Kbps modem).
Drag and Drop File Transfer
---------------------------
Besides using file transfer by drag-and-drop, you can also choose Send from
the File Menu of Connectix VideoPhone
ISDN - How to dial two B-channels (data)
----------------------------------------
In order to establish a connection using both B-channels for the Connectix
VideoPhone, the both ISDN phone numbers should be entered in the address
book with the '&' character between them.
ex. 555-1212&555-1313
This will try to make a connection using both B-channels for Data.
ISDN - How to dial one B-channel voice and one B-channel data
-------------------------------------------------------------
This feature has only been tested with the BitSURFR Pro ISDN modem. This
feature allows Connectix VideoPhone to make a voice call on one B-channel
(using a telephone plugged into the BitSURFR Pro's analog port) and a data
connection on the other B-channel. The ISDN phone numbers should be entered
in the address book with the '*' character between them.
ex. 555-1212*555-1313
^ 1st ^ 2nd
B-channel B-channel
This will place a voice (telephone) call on the second channel and a data
call on the first channel. Using this configuration, one B-channel is used
by Connectix VideoPhone for video and the and the audio will be handled by
the voice call.
Modem Dialog in Communications Port Setup
-----------------------------------------
When using the Connectix VideoPhone in Direct Modem/ISDN mode, the
software will use the default initialization string. If you encounter
troubles connecting or staying connected to other users, you may
want to select your specific modem. From the menu, select Settings,
Preferences, Communications Port Setup, Select the Advanced tab. In the
lower section, from the list box, select your specific modem. This should
increase the reliability of the connection. If your modem is not listed,
please obtain the modem's Manufacturer Name, Brand Name, Model number and
contact Connectix Technical Support. See 'How to Contact Connectix' below.
=========================================================================
7. What is ULS and How does it Work ?
=========================================================================
ULS is a protocol that dynamically, without user intervention, translates
a persons E-mail address to their IP address each time they log into the
Internet. In addition to solving the dynamic IP address problem, ULS also
enables CVP to know if a person is currently logged into the Internet
before a call is placed, therefore improving the chances that a call is
actually completed. By using ULS, CVP will also be able to randomly call
people that are known to be on the Internet.
For technical information about ULS, see
INTERNET-DRAFT: draft-williams-uls-00.txt
on the InterNics WEB Site:
http://www.internic.net/ds/dspg0intdoc.html
=========================================================================
8. Supported Video Capture Devices
=========================================================================
The Connectix VideoPhone product development staff is constantly working to
add more video capture cards to our supported list.
For a complete list of supported video capture devices, refer to our
"Connectix VideoPhone Compatibility" document. This can be found on all of
our on-line services. See "How to contact Connectix Corporation"
=========================================================================
9. How To Improve Captured (Static) Image Quality
=========================================================================
Images captured using the snapshot utility are stored as full 24 bit
images. When they are displayed on your monitor, they are displayed
as windows bitmaps using the VGA driver/monitor. The quality of the
image on your monitor will depend on the VGA card you are using, and
the VGA driver you have installed under Windows.
Try the following to improve the quality of static images that are
displayed by the film roll dialog and the address book:
Use a VGA card that supports 256 or more colors to be displayed,
and use Windows Setup utility to load this driver. The Standard
VGA driver allows 16 colors to be displayed in normal video
mode. Modern VGA cards with at least one megabyte of ram on
board will support 256 or even 32 thousand colors. The more
colors that the VGA card and driver supports, the better the
image quality will be.
Use the right VGA driver for your VGA card. Don't forget to
activate the enhanced color depth of your VGA card with the
appropriate driver from the windows setup utility. These
drivers are available from your VGA card manufacturer.
=========================================================================
10. Generic Windows Sockets V1.1
=========================================================================
If the TCP/IP product that you are using provides a WinSock interface
(WinSock.DLL), make sure the directory that the file WinSock.DLL is located
in is in your PATH variable (set by autoexec.bat). There should be only one
file named WinSock.DLL in your path at any time.
Note that the following TCP/IP products have been approved to run with
the Connectix VideoPhone:
Windows 95 built in TCP/IP from Microsoft
