To enable content rollover in case of encoder failure

1. In the Windows Media Playlist Editor, expand the playlist, and then expand the smil element to show the elements in the playlist.
2. On the toolbar, click the Add element button.

   The Add Media Elements dialog box appears.

3. In Location of content, specify the URL of the encoder that will be the primary source of content for the broadcast.
4. Repeat steps 2 and 3 to specify the location of the alternate content source for the broadcast. This content will be streamed when the encoder session ends or if there is an interruption in the encoder stream. The alternate content source can be another encoder, an advertisement, a remote publishing point, a playlist, or a digital media file or files.
5. You can change the value of the repeatCount attribute of the smil element to Indefinite if you want the server to switch back to the original encoder in the case of secondary content source failure. For more information about changing attribute settings, see To change the value of an offline playlist attribute.
6. Name and save the new playlist.
7. In the console tree, click the broadcast publishing point for which you want to enable content rollover.
8. In the details pane, click the Source tab.
9. In Content source, click Change.

   Change <publishing point> content source on <server> appears.

10. In Location, type the name and location of the playlist you created in the first five steps.

Note

• By using redundant encoders and a rollover playlist, you can greatly improve the reliability of your broadcast stream. You can further increase reliability by using load balancing techniques.
