Multicast Playback
There are several ways to play the multicast stream from your VBrick WM Appliance on
Windows Media player. The following playback options all use the .asx file and therefore
offer all the .asx features including Program Name, Author, Copyright, Banner, and Log URL
that are configured on the Announce (SAP) screen. The .asx file uses a URL reference to the
NSC file on the WM Appliance so these playback methods also offer all the features of the
NSC file including the Unicast Rollover URL, Allow Stream Splitting, Allow Fast Caching,
Cache Expiration Time, and Network Buffer Time.
T To play back a multicast stream:
• Launch the player directly from the IWS by clicking

. This is
a good way for the WM Appliance administrator to easily view the stream when adjusting
various encoder parameters via the IWS.
• Right-click on
Click here to play multicast
and select
Save Target As
to save the .asx
file on your computer. You can then double click the .asx file to launch the player and
play the multicast stream. E-mail the .asx file or make it available on a shared network
drive to allow other viewers on your network to play the multicast stream.
• Play the multicast stream from a browser or from a standalone player using the URL
http://vbrickipaddress/vbs1multi.asx . (The WM Appliance serves the .asx file via
HTTP.) The URL to the multicast .asx for Slot2 of a dual WM Appliance is http://
vbrickipaddress/vbs2multi.asx .
• Use VBrick's StreamPlayer product to add an automatic program guide to Windows
Media Player so when you run StreamPlayer it will automatically list all the multicast
programs available on your network. The user can then click on a program to launch
Windows Media Player to play the stream. (The WM Appliance can send network

Unicast Rollover URL When present, the player will try to use the rollover URL to play the
stream if it cannot receive the multicast.
Allow Stream Splitting Tells receivers of the multicast stream whether they should be
allowed to replicate the stream to multiple clients.
Allow Fast Caching Tells receivers of the multicast stream whether they should be
allowed to cache the stream to disk.
Cache Expiration
Time The cache expiration time in seconds. Tells receivers of the multicast
how long a cache of the stream is valid.
Network Buffer Time The buffer time in milliseconds. Adjusts the depth of the player's
network buffer.
