Server-Side Playlist Object
A Windows Media server always creates at least one playlist object in memory for each connected client. It can create additional playlist objects depending on whether the client connects to an on-demand or a broadcast publishing point. For more information, see the following sections:
The server uses playlist objects to determine which streams to send to the client. You can use the server object model and the XML Document Object Model (DOM) to create or modify playlist objects programmatically. For more information, see the following sections:
Playlist objects are created by playlist parser plug-ins. Windows Media Services provides the WMS SMIL Playlist Parser plug-in for creating playlist objects from documents containing elements and attributes based on the SMIL 2.0 specification. Windows Media Services also contains the WMS Directory Playlist Parser plug-in for creating a playlist object referencing all of the media files in a directory. You can create your own plug-ins to parse other playlist formats. For more information, see Creating Playlist Parser Plug-ins.
