Web Playlists is an IIS Media Services extension that provides developers and hosters unprecedented control of how media content is delivered to users. Powerful customization features make it possible to monetize media delivery scenarios by inserting in-stream or pre-roll video ads and dynamically determine the content to be delivered based on the session history and configurable server-side rules.

Control playback of digital media files from IIS using playlists

The Web Playlists extension allows you to create server-controlled sequences of digital media content and prevent caching of content on client computers. The delivered playlists protect the direct URLs to your content and allow you to monetize the content through advertising. Web Playlists are created in IIS using a playlist format based on the W3C Synchronized Multimedia Interface Language (SMIL).

Monetize media scenarios with no-skip advertising content

Web Playlists allows you to control the order and playback of media content, and prevent users from skipping advertisements. In addition, you maintain control of whether content is cached on client computers. The Web Playlists feature generates client-side playlists dynamically per request, allowing you to personalize and control the media delivered to each user.

Extend existing applications and control the format of your playlists

By default, web playlists are simple to create and deliver. To personalize the experience, you can dynamically change the content of each client-side playlist by implementing custom providers and by leveraging existing web applications such as ASP and PHP. In addition, the output of the client-side playlist can be transformed to any XML format by using the Extensible Stylesheet Language (XSL).
