IIS Media Pack 1.0 Released


The IIS Team has released the final version (1.0) of the IIS Media Pack.

IIS Media Pack 1.0 currently includes the Bit Rate Throttling and Web Playlists extensions for IIS 7.0, which enable you to:

  • Save bandwidth costs by throttling the speed at which content is downloaded
  • Decrease network traffic by metering your media deliveries
  • Monetize media assets with Web playlists that personalize content and prevent ad skipping
  • Intelligently deliver multiple media formats from a single server, including .wmv, .flv, and .mp4 files

Rich media usage is exploding on the Web, and seventy percent of videos are delivered from Web servers. IIS Media Pack 1.0 provides media-specific IIS extensions that make Web server delivery of media simple and cost-effective. Building on the security, reliability, and manageability of IIS 7.0, IIS Media Pack 1.0 protects media assets as it increases scalability by supporting more concurrent users per server.

Bit Rate Throttling

Bit Rate Throttling lets Web server administrators meter the delivery of multiple media file types as well as data. By controlling how fast or how much data is downloaded to the client, site operators can see significant bandwidth cost savings for rich media content that has a high drop-off rate. Additionally, by controlling how much data is sent to the client, the number of concurrent users per server will increase.

Web Playlists

Web Playlists let you deliver server-controlled media playlists from your Web server infrastructure rather than using a dedicated streaming server.  They enable you to control whether clients can Seek or Skip for each media asset, which lends itself very well to monetizing your content with pre-roll and in-stream ads. Web Playlists also obfuscate the location of media assets from the end user, and prevent client-side caching of those assets.

More extensions

In the future we’ll see more extensions for IIS 7.0, this is just the beginning. A future extension would be Smooth Streaming, which enables adaptive streaming of media to Silverlight clients over HTTP.  This provides a high-quality viewing experience that scales massively on content distribution networks.
