Before You Begin - Polycom PVX Release Note

Installing Polycom PVX Version 8.0.2

Before You Begin

The CPU speed for H.263+ video is based on the Low camera driver load setting.
To check this setting, see the For the camera you have selected, specify the
camera driver's load on the system field on the Setup > Video > Advanced page.
If your camera driver load setting is set to High or Medium, you must manually
compensate for the different setting as follows:
• If your camera driver load setting is set to High, subtract 600 MHz from the
speed shown. For example, if your system's CPU speed is 2000 MHz, subtract
600 MHz from that, for a total of 1400 MHz.
• If your camera driver load setting is set to Medium, subtract 200 MHz from
the speed shown. For example, if your system's CPU speed is 2000 MHz,
subtract 200 MHz from that, for a total of 1800 MHz.
For more information about the camera driver load, refer to the Selecting Audio
and Video Devices for Use with Polycom PVX document, available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf.
If you have ViaVideo version 5.x or earlier currently installed on your system and
you wish to preserve user preferences and directories, you will first need to
upgrade to Polycom PVX version 6.x before upgrading to PVX version 8.0.2.
Polycom PVX 6.x downloads and release notes are available on Polycom's
website at www.polycom.com/videosoftware.
If you have ViaVideo version 5.x or earlier and do not need to preserve user
preferences and directories, then use the Windows Add/Remove Programs
Control Panel to uninstall ViaVideo and install PVX version 8.0.2 as directed in
the next section.
If you are upgrading from PVX version 8.0.0, be sure that you select Use local
settings on the Setup > GMS page before you begin the upgrade to version 8.0.2.
(If Use provisioned settings is selected, some of the settings might get lost during
the upgrade.)
