Release Notes

ViaVideo 5.1

This Polycom®ViaVideo™ multimedia conferencing system software release bulletin provides

information about maintenance update 5.1.

What’s New in 5.1?

If you are currently using software version 3.x or 5.0, Polycom recommends that you install

update 5.1. This maintenance update contains the following improvements from version 5.0:

Improvements to the user interface, based on customer feedback.



• Improved legibility

• Easier access to controls

• Streamlined configuration pages

Directory enhancements

• New speed dial list.

• User option to display local and global directory entries either together or

separately.

• Support for saving to the directory calls dialed using an E.164 address and calls

dialed through a gateway.

• Improved directory searching. The directory’s search feature now returns all

directory entries with words that start with the search criteria. Previously, the

search returned only those entries whose first word started with the search

criteria.

• Faster directory look-up

Improved integration with Polycom’s Global Directory Server (GDS). Systems

configured to auto-start ViaVideo in the background now register with GDS on system

startup. Previously, ViaVideo would wait for the main user interface to be launched

before it registered.

Enhanced security options. Administrators can now disable VideoMail and outgoing

calls.

Improved VPN performance.

Release Notes

ViaVideo 5.1

What’s New in 5.0?

ViaVideo 5.0 introduces enhancements including easier connectivity, a new Windows-like user

interface, and integration with other version 5.0 Polycom Office products including the MGC

bridge, ViewStation products, PathNavigator, and Global Management System (GMS).

The ViaVideo 5.0 features include:

Increased Data Rates

ViaVideo 5.0 now supports calls up to 512 Kbps. At speeds above 320 Kbps, you will

see crisp, clean video motion with video frame rates of up to 30 fps.



User Interface Enhancements

Based on customer feedback, we have redesigned the user interface for ease of use. The

interface now looks and behaves more like other Windows applications and is therefore

more intuitive for Windows users. The application now has resizable and detachable

windows.

The look and feel of the web interface has matured. Navigation is significantly enhanced

and security can be set from almost every page.

You can now set the ViaVideo interface to use these four additional languages:

Traditional Chinese, Simplified Chinese, Korean, and Norwegian. As in the previous

version, you can also use ViaVideo in English, French, German, Spanish, Italian,

Portuguese, or Japanese.

ViaVideo 5.0 has over 100 new messages that provide descriptive information in the

event of an error. These errors are also reported in the Call Detail Record.

Location Profiles - Home, Office, Travel

We’ve made videoconferencing for travelers much easier with customizable location

profiles. ViaVideo now provides location profiles that allow you to set up and save

network characteristics for Home, Office, and Travel use.

You only have to set up your location profiles once. After that, every time you start the

ViaVideo program, simply select which of the three location profiles you want to use and

you will be ready to place and receive calls.

Video Enhancements

ViaVideo 5.0 offers one of the most requested features – full screen video! This feature

allows you to increase the size of the meetings you conduct with ViaVideo. Now you can

gather in small groups and everyone can easily see the remote location. If you are in a

multipoint call, using Conference on Demand, the quadrants are large enough in full

screen mode for everyone to view the remote locations. To switch to full screen mode

during a call, click the icon in the top left corner of the main window. To return to normal

viewing mode, simply press the Esc key.

Version 5.0 now allows for multiple monitors to be used in conjunction with the

ViaVideo application. Two or more VGA displays can be attached to your PC or laptop,

expanding the desktop conferencing space for enhanced visual collaboration.

Enhanced Configuration Options

In this version, integrated Polycom Video Error Concealment (PVEC) allows ViaVideo

to use the highest possible picture quality and frame rate, providing clear audio and video

connectivity even on congested networks.

Release Notes

ViaVideo 5.1

ViaVideo 5.0 now registers directly with the Global Management System (GMS), just as

the ViewStation products do. In previous versions, ILS registration was required in order

to register with the Global Address Book. ILS registration is still an option for those who

have applications calling for it.



ViaVideo 5.0 allows for three GMS server entries and three ILS server entries.

ViaVideo can now auto-detect your VPN’s dynamically-assigned IP address.

The addition of canMapAlias now provides the gatekeeper with more control in routing

the call by allowing it to tell the endpoint to modify the destination address.

ViaVideo now supports alias recognition for E.164 addresses. When you select another

system to dial from the directory and when ViaVideo is on a network connected to a

gatekeeper, ViaVideo automatically dials using that system’s E.164 number (extension) if

one is available. If an E.164 number is not available, then ViaVideo uses the IP address.

For example, if Mary Smith has a system with an extension of “3456”, and an IP address

“255.255.255.0”, your ViaVideo will dial using the extension “3456” when you call

Mary Smith's system using your Directory.

New VideoMail Format

ViaVideo VideoMail now supports .asf files. The .asf file format can be played by all

recent versions of MediaPlayer and RealPlayer. In addition, .asf files are usually about a

quarter of the size of a corresponding .avi file, with no loss in video quality.

Enhanced Help Features

To make ViaVideo even easier to use, we’ve developed ‘What’s This?’ Help for all of the

interface items. If you need more information about an interface option, click the ‘?’ icon

in the top left corner of the application, select What’s This?, then click the item on the

interface to see an explanation.

We have also enhanced our application help to cover all topics concerning network

configuration as well as general usage.

Enhanced Configuration Security

ViaVideo 5.0 provides enhanced security of configuration settings by allowing

administrators to password protect individual setup screens.

Extensive Windows Support

The ViaVideo 5.0 device drivers have been certified by Microsoft to be compatible with

Windows XP and Windows 2000.

ViaVideo can be used with Windows XP, 2000, 98 SE, and ME.

Issues and Restrictions

The following types of issues are described in this section:

General Issues Hardware Issues Network Issues

Audio Issues Installation Video Issues

Calling Issues Microsoft Windows VideoMail Issues

General Issues

In video calls of 256k and below, customer may experience a slight video delay due to

PVEC compensation.



If snapshots taken locally or in a call are not displayed in a maximized browser, increase

the time between snapshots to 5 seconds or more. The extra time allows the first snapshot

to arrive completely before delivering the next snapshot.

If the system is registered with an Internet Locator Server or a Global Directory and you

delete the server address, the system displays a server error message. Uncheck the

the ViaVideo icon appears in the system tray. Double-clicking this icon does not launch

ViaVideo. To launch ViaVideo, use the start menu.

The VideoMail display in the Setup Wizard intermittently fails. This does not affect the

VideoMail feature.

Audio Issues

Users may experience various audio anomalies using USB audio. Polycom recommends

using analog audio instead.

You may notice loss of far-end audio when you speak at the same time as the far end.

Users may experience audio clipping in a videoconference call when minimizing or

maximizing the any application. To avoid audio clipping, set applications to 75% of the

maximized screen size.

Users may notice an increase or decrease of the audio volume level when starting the

ViaVideo application.

Customized Sound Events ViaVideo 5.0 does not support customized sound events.

Users who upgrade from ViaVideo 2.5 or later will lose their customized sound events.

When users are in an audio-only call, they may lose their local video if they click the PIP

button. To avoid this, do not click the PIP button in an audio-only call.

Calling Issues

If your system is registered with a gatekeeper, you must use quotes when you call an alias

or extension that includes a space in the name. For example, to dial Polycom Austin as an

alias, you must enter “Polycom Austin” in the address field to connect the call.

The Global and Local directories are not currently available in the web interface.

When you select a call speed in the Directory window, the speed you select becomes the

default for all calls placed from the directory.

If you change the available speeds on the directory drop-down list (via the H.323 >

Dialing Speeds tab), If you remove the current directory default speed, you must go back

to the directory and explicitly change to the new speed. If you do not select a new speed

Release Notes

ViaVideo 5.1

in the directory, ViaVideo will continue to place calls at the previous default speed, even

though that speed no longer appears in the list. This issue will be addressed in a future

release.

If users are having problems with E.164 or ISDN dialing, check on the Setup > Directory

screen that they have the Dial using H.323 extension when connected to a gatekeeper

option enabled.



Users may see incorrect information in the Recent Calls tab when dialing E.164 prefixes

through an MCU. This issue will be addressed in a future release of the ViaVideo

software.

Hardware Issues

In this version, the software may intermittently fail to recognize the camera. If this

happens, close the camera’s shutter and open it again.

Users using USB hubs may experience problems loading the camera’s firmware. If this

happens, connect the ViaVideo unit directly to computer’s USB port.

Users may experience a computer system lockup when placing an outbound

videoconference call while recording data to a CDROM recorder. To avoid this, complete

the call before recording data to a CDROM.

Users may experience increased CPU usage when mousing over buttons and icons in the

ViaVideo application.

When you use WebOffice to run ViaVideo on a docked laptop, ViaVideo may not appear

to be running if you undock and then redock. If this happens, close the camera’s shutter

and open it again.

Users using laptop docking stations may experience problems loading the camera’s

firmware. If this happens, connect the ViaVideo unit directly to computer’s USB port.

Some Windows 2000 systems may fail to exit stand-by mode if they entered stand-by

while ViaVideo was running. On these systems, exit ViaVideo before entering stand-by

mode.
