Configuring a Macintosh for Tunneled Streams
You may need to perform certain configuration steps on a Macintosh before you can use
QuickTime to view streams tunneled over HTTP from a VOD-W server.
T
To configure QuickTime for tunneled streams:
1. Launch QuickTime on a Macintosh and click on the
Apple QuickTime
player to set focus
on the task bar at the top of the screen.
2. Click
QuickTime Player
in the task bar and go to
QuickTime Preferences
.
3. On the
Advanced
tab, click on
Transport Setup
and then
Custom
.
4. Check the
Port ID
used for the HTTP
Transport Protocol
. The
Port ID
must match the
HTTP Tunneling Port
set on the Portal Server for the VOD-W server (default = 8000). If
necessary, get this port number from your system administrator. See the VOD-W Admin
Guide for more information.
Linux PCs
If configured with the appropriate components, Linux PCs running Fedora or Red Hat
(on Firefox) can play MPEG-1, MPEG-2, MPEG-4, and WM streams. However, the
Portal Server must download Linux components to
each-end user desktop before any streams
will play. This should only be performed by a system administrator. When you access the
Portal Server for the first time, you will see a message in the embedded player window
indicating that the appropriate plugins are not installed. See "Installing Linux Components"
in the
Portal Server Release Notes for detailed instructions. On Linux PCs, Portal Server
functionality is the same as in Windows except that the
Add Video
feature is not available.
Table 4 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
Linux environments; see the
ETV Portal Server Release Notes for information and
recommendations.
