Setting up a multicast

If you are multicasting a Windows Media-based stream, you must generate a stream format file because it contains information that the player uses to decode and play the stream. For example, the types of media contained in the stream (audio, video, and script), the audiences, and the codecs used to encode it. The stream format file has an .asf extension.

You can use the encoder to create the stream format file, and the Windows Media Services Administrator on the Windows Media server to add the file to the list of supported stream formats on your multicast station.

Note   If you are creating a new multicast station using the QuickStart Wizard, you must use the station properties to add the stream format file manually. The QuickStart Wizard does not recognize .asf extensions for stream format files.

The multicast station contains all of the information needed to deliver a Windows Media stream to a player, including the IP address, port, time-to-live (TTL), value, and so on.

For more information about creating and managing multicast stations, see Windows Media Services Help.
