users will also be required to install an additional plugin when they use Add Video for the first
time (again, if they are configured with this privilege).

Locked-Down Windows PC s
As described above, the Portal Server automatically downloads components to client PCs
depending on the Global Assignment setting. This download can be an issue in environments
that have restrictions on client software installation. For playback of WM files, Portal Server
uses the existing Windows Media Player components on the client PC and there is no need
for the extra components to be downloaded. This means that Portal Server and WM can be
used in some but not all restrictive or "locked-down" environments.
Even if downloads are configured, a client PC will still refuse to accept the component
download if the Internet Explorer security feature Download signed ActiveX controls is
disabled. When using Portal Server 4.0 exclusively with WM streams and a WM VOD, the
client PC can refuse to accept the downloaded components and all Portal Server features
except Add Video will work. In this case you should uncheck the Add Video Utility in Global
Assignments.
Some sites also require that their PCs be configured with certain Internet Explorer security
settings. The Portal Server will not work on clients with Internet Explorer security set to
High. The Portal Server will work at any level at or below Medium. If you start at High, the
client will still work with Portal Server if you enable Run ActiveX controls and plug-ins, Script
ActiveX controls marked safe for scripting, and Active scripting.
Since firewalls on LAN client PCs can also cause problems with Portal Server, it is
recommended that firewalls be disabled on LAN clients. (In Windows XP with Service Pack
2, the f irewall is enab led by de fault. ) Portal Server 's suppo rt for Intern et clien ts is de signed t o
work through firewalls. If you have Internet clients with firewalls see the description of
LAN/Internet address ranges in Global Assignments on page 19.
Macintosh PCs
If configured with the appropriate components, Macintosh PCs (with Safari or Firefox)
can play all stream types including MPEG-1, MPEG-2, MPEG-4, and Windows Media.
In a Macintosh environment, if downloads are configured in Global Assignments, when you
launch the ETV Portal Server for the first time, the Home page (see Figure 2) displays a link
prompting you to download components that are appropriate for your computer. If you
agree, these components are automatically installed and no additional download is necessary
for subsequent access. On Macintosh PCs, Portal Server functionality is the same as in
Windows except that the Add Video feature is not available. Table4 shows the stream types
supported for each environment; Table 5 shows the operating systems that are tested and
supported. Note that there are certain performance limitations in Macintosh environments;
see the ETV Portal Server Release Notes for information and recommendations.
