Release Notes

Polycom PVX Version 8.0.2
What's New in Release 8.0.2?
What's New in Release 8.0.1?
May 2006
3725-22754-006/A
Polycom is pleased to announce the release of Polycom PVX™ version 8.0.2.
Polycom PVX version 8.0.2 delivers unprecedented technology and
performance to computer video conferencing. With premium audio and video
algorithms and enhanced collaboration features, the Polycom PVX software
delivers power and performance never before seen in computer video
conferencing.
Working together with a computer and a standard USB camera, the Polycom
PVX 8.0.2 software application brings video conferencing to your desktop. It
is ideal for employees who work from home, sales or consulting professionals
who travel, educators conducting distance learning events, or health care
professionals delivering services in remote facilities. Polycom PVX software
extends Polycom's unmatched capabilities and conference room performance
to the desktop.
Polycom PVX 8.0.2 will continue to support the ViaVideo™ and ViaVideo II
cameras. However, Polycom recommends using standard USB 2.x webcams to
achieve the highest video quality. When you choose a standard webcam, the
computer's processing capabilities let you use additional features such as
H.264 and Siren™ 14. View-only mode allows users without cameras to
participate in video conferences using audio and to share content using
People+Content™ and standards-based H.239.
Polycom PVX 8.0.2 is a maintenance release. This release includes general
improvements to SIP interoperability and stability, support for the SIP Express
Router (SER) SIP server, and other minor improvements.
Polycom PVX 8.0.1 is a maintenance release. A number of minor
improvements have been added to PVX for this release; however, the major
change is that you can now specify the CPU resources required by your
camera.
A new tab, the Advanced Tab, has been added to the Video page. Settings on
this tab allow you to configure PVX to compensate for a higher CPU load from
your camera driver. You can lower the estimated CPU power by a fixed
amount and, thereby, enhance the quality of your PVX video.

  • Page 14 If that user is the first user on the computer, PVX will initialize the computer-specific properties, as well. At first launch, PVX displays a setup wizard to help the user to set up the system. Alternatively, an administrator could provide a .pvp initialization file that contains the initial settings.
  • Page 15 Set to TRUE or FALSE. H323_QOS_ENABLE = TRUE • If you use a .pvp file to specify a gatekeeper, GDS, or ILS, the PVX will not register with these servers until the PVX application is restarted. • If you use PVXSET to change the system’s H.323 name, the H.323 name is reset to the User Name when you restart PVX.

  • Page 22 PVX calls that are transferred to an invalid extension will display black video and require manual disconnection of the call. When a call is placed from a PVX system registered to a gatekeeper to an endpoint with call forwarding activated, the entry saved to the address book when the call completes will need to be modified.
  • Page 23 The QoS tab on the Setup > Network page has been simplified so that a single setting allows you to enable or disable QoS. In PVX version 8.0.0, IP Precedence and DiffServ had to be set separately, which did not work reliably on all Windows systems.
