Output Formats Page

Web playlist files (files that have .isx file name extensions) use XML that is based on the Synchronized Multimedia Integration Language (SMIL) 2.0 language specification. Web Playlists delivers media assets referenced in .isx files as Advanced Stream Redirector (ASX) bit streams in the HTTP response to clients. The ASX format is also based on XML. Players that support ASX include Windows Media® Player and Microsoft® Silverlight®.

noteNote
For more information about the XML syntax in Web playlist files, see Playlist XML Format.

You can use Extensible Stylesheet Language Transformations (XSLT) style sheets in Web Playlists to filter or customize the XML data in a Web Playlist file so that it can be used by other applications. For example, you can create an XSLT style sheet that transforms the Web Playlists response so that the data is rendered by players that do not support the ASX format. You can also create an XSLT style sheet that transforms the Web Playlists file format to a Web feed format, such as Atom or RSS.

noteNote
For more information about how to write XSLT style sheets that work with the ASX format, see Extending Output Formats using XSLT.

Use the Output Formats feature page to manage the XSL transformations that you create for Web playlist files. You can sort the list by clicking one of the feature page column headings or select a value from the Group by drop-down list to group similar items.

The following tables describe the UI elements that are available on the feature page and in the Actions pane.

 

Element Name Description

Format Name

Displays the format name that must be specified in the playlist URL for the user (for example, http://server_name/playlist_name.isx?format=format_name), where format_name is any name that you use to identify the output format (for example, atom).

XSLT Path

Displays the path of the uploaded XSLT style sheet, relative to the site root (for example, /xslt/atom.xsl).

Enabled

Displays whether the XSL transformation is enabled on the Web server.

Content Type

Displays the MIME media type setting for the output format (for example, application/atom+xml). The MIME media type setting identifies the file format on the Internet. For a complete list of registered MIME media types, see the Internet Assigned Numbers Authority (IANA) Web site.
