At the start of November, when it released IIS Media Services 4.0 to manufacturing, Microsoft promised that a new version of the IIS Smooth Streaming Client would follow soon enough. The Redmond company certainly lived up to the promise, with version 1.5 of the IIS Smooth Streaming Client hitting release to web (RTW) at the start of December 2010.

IIS Smooth Streaming Client 1.5 RTW is now available free of charge via the Microsoft Download Center, and customers looking to offer customers on-demand and live IIS Smooth Streaming content should have a look at the technology.

The focus with IIS Media Services 4.0 was placed on offering rich media experiences across three screens, and the IIS Smooth Streaming Client 1.5 makes it possible for content to be served to Silverlight and Windows Phone 7 applications.

In addition to on-demand and live streaming capabilities, IIS Smooth Streaming Client 1.5 sports a variety of other features including full DVR, live ad insertion, multiple camera angles, trickplay, etc., according to Microsoft.

Obviously, customers looking to leverage version 1.5 of the IIS Smooth Streaming Client 1.5 will also need IIS Media Services manifest compression. At the same time, IIS Smooth Streaming Client 1.5 is designed to work in concert with IIS Media Services 4.0 or higher.
