Depending on the selections you made in the wizard, you must to
name and save some or all of the following types of files:
Multicast information file name. Enter a name and
location for the multicast information file or accept the default.
The file must have an .nsc file name extension. This file contains
information a player needs to access and decode the stream, such as
the IP address, port, and stream format. You should save this file
to a location that can be accessed by clients when they are
connecting to your multicast broadcast, such as a network shared
folder or a Web folder. Clients must obtain this file before they
can receive a multicast stream.
Announcement file name. Enter a name and location for
the announcement file or accept the default. This file directs
clients to the multicast information file. It can either be
directly opened by the player or embedded within a Web page. If you
are going to use your announcement file with a Web page, make sure
to save it in a location that is accessible to your Web server and
Web page with embedded player. Enter a name and location
for the Web page or accept the default. This is an automatically
generated Web page with an embedded Player control that a user can
use to access the multicast stream. You should save this file in a
location that can be referenced by your Web server.
Copy syntax for embedding a player to clipboard. Select
this check box if you want to copy the HTML code for the embedded
Player control to the Clipboard. You can then use the code as part
of an existing Web page.
If you make the multicast information file
available on your Web server, be sure to configure the Web server
to either not allow caching of the file or to require a "freshness"
check when cached by a client. This will prevent players from using
multicast information that is outdated.
If you want to select the Test files when
this wizard finishes option at the end of the wizard, you must
either enable Internet Information Services (IIS) on your computer
or save the .nsc file to a computer that has IIS enabled or to a
public Universal Naming Convention (UNC) share location. Then, on
the Specify URL to Multicast Information File page, select
the Network share option.
The server does not use your user account to
access folders and other resources; it uses the Network Service
account by default. If you are saving files to a location other
than C:\WMPub and its subdirectories, make sure that the folder is
shared and that the Network Service account has read and write
permissions for the folder. If the Network Service account does not
have permissions for a folder, the server will not be able to save
files to it. For more information about rights and permissions, see
Multicast streaming and the WMS Multicast Data
