SHAREVISION SOFTWARE RELEASE v1.4 & 2.0
(*) denotes information for ShareVision PC3000 only (not for
PC300)
IMPORTANT SHAREVISION PRODUCT
INFORMATION
ò ShareVision v1.4 should be installed on Win 3.1 systems. ShareVision 2.0
is for Win 95 systems.
ò ShareVision v2.0 is currently a 16 bit application and will not take
advatange of some Win 95 32 bit features such as long filenames and
multitasking. ShareVision v3.0 will be a full 32 bit application
supporting all the Win 95 features.
ò Remote Software Update:
ShareVision v1.4 may not be able to upgrade earlier versions
of ShareVision. ShareVision 2.0 cannot upgrade any of the previous
Windows 3.1 versions. At the time of connection, software version
information is exchanged between the two ShareVision systems. If
the remote party has an older version, you will be presented with
the Remote Update dialog, allowing you to update the remote user
to the current software version. If you choose not to update and
continue with the current connection, you may later invoke the
Remote Update feature from the main ShareVision menu. Any
registered user may obtain the 1.4 and 2.0 installation diskettes by calling
the nearest Creative Customer Support Center : North America 1-
800-998-1000; Singapore (Tel) +65 773-0233, (Fax) +65 773-
0353; and Europe (Ireland) (353) 1-820-7555.
ò Windows Language Versions:
Windows language versions supported in the v1.4 and 2.0 release: English.
GENERAL PRODUCT TIPS
ò When using ShareVision internationally, you will attain optimal
connection rates if the ShareVision modem answers the call for an
immediate connection (rather than answering with a normal
telephone and connecting with ShareVision later). The reason for
this is that in normal voice telephone calls, an ADPCM channel
(compression) is usually assigned by the network. A clear channel
is provided only if the modem answer tone is detected for a digital
connection. The set up is called "DCME/DCMS interaction". If a
ShareVision user starts the video conferencing session with an
analog (normal telephone) connection first, and then switches to a
digital (ShareVision) connection, he/she will be forced to a lower
data rate due to this constraint. A difference of 4.8kbps is likely.
This situation is less critical for domestic US calls where a clear
channel is assigned most of the time.
ò If you notice that the video is breaking up or that the audio is
choppy, you are probably dropping packets of data due to poor
telephone line quality. If this is the case, hang up and reconnect at
the same baud rate. If you consistently have problems with line
quality connect at a lower baud rate. Note that the default
connection rate after installing ShareVision is 24kbps. For some
users this connection rate will be unattainable due to local telephone
line conditions. If this is the case, change your Modem Settings in
the Dialer to a lower baud rate. Refer to the manual for more
information on changing the connect rate in the modem settings
dialog. As you gain experience with using ShareVision you will get
a feel for your connection capabilities as well as the capabilities of
the parties you are calling.
ò Audio always has the bandwidth that it needs (4.8kbps) to
transmit. However, video dynamically adjusts depending upon how
much talking and data sharing you are doing. It is normal for video
to slow down, or to temporarily stop while sharing lots of data--as
in the case of a transferring a file or initially sharing an application.
ò If the modem activity dialog is reporting that the average frame
rate is consistently below five frames per second (at 28.8kbps
connect rate), your PC may be too slow for the current core video
capture size. Self video preferences has a menu item 'Video Core
Size' that allows you to dynamically change the core capture size,
even while connected. The smaller the core capture size, the less
compute your PC has to perform. Also, since the incoming video
stream is decoded on your PCÆs processor, you will want the
remote party to reduce their core capture size as well.
ò To facilitate faster whiteboard transfers, we recommend turning
off DOS SHARE.EXE in the AUTOEXEC.BAT.
ò When using ShareVision, several drivers are loaded into low
memory. Additional drivers will be loaded into low memory if you
are using scanner input devices or using the application sharing
feature of ShareVision. Depending upon the constraints of your PC,
you may need to install a memory manager such as EMM386,
QEMM, or 386MAX. Where possible, these utilities will load
drivers into high memory to free up low memory.
ò When running ShareVision software, we recommend that virtual
memory be turned on with Swapfile Settings of 19+MB and
Permanent.
ò If for some reason your software becomes corrupted or otherwise
unusable, run the ShareVision Uninstall application to remove all
files and undo all modifications to system files. Afterward, reinstall
from the ShareVision installation diskettes.
TECHNICAL NOTES
ò (*) There is a compatibility issue between some VGA boards and
Video For Windows displaying in 16-bit DIB format. On these
VGA cards, the video will appear to have a mismatched
(psychedelic) palette. If you experience this display problem, you
can correct the problem by changing from 16 bit to 24 bit DIB in
the Self Video preferences. Changing to 24 bit DIB will have a
marginal effect of slowing down video.
ò The video display driver for the Tseng Labs ET4000/W32 at
640x480x8-bit will cause a crash with Video For Windows when
you run the ShareVision software (640x480x8-bit is the default
resolution for the Compaq Prolinea systems). The Tseng driver will
not crash at other resolutions or depths (i.e.,
640x480x16-bit).
ò If you have Sound Blaster installed in your PC, please note the
following. Because of a conflict between MicrosoftÆs
MSACM.DRV (which is installed with Video For Windows) and
Sound Blaster software, you may experience rare General
Protection Faults (GPFs) in module USER.EXE. In this case
contact Creative technical support for a software upgrade of the
CSPMAN.DLL. Or, you can avoid this problem by editing your
SYSTEM.INI file. Add semicolons to comment out the following
two lines:
;MSACM.msadpcm=msadpcm.acm
;MSACM.imaadpcm=imaadpcm.acm
ò When application sharing, there may be times that colors and fonts
at the host side are not available at the guest side. In these cases,
the colors and fonts are matched as closely as possible.
ò When application sharing, regions of a window at the host that are
obscured by another window or dialog will not be updated at the
guest side.
ò When application sharing, in version 2.0 of ShareVision, if the
host side is printing a document from any Windows'95 application, the
printer will output blank pages.
