-
- 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.
