Microsoft is set to announce its alternative to Flash, Adobe’s rich media application for the Web.

Forest Key, a director of product management for Microsoft's Server and Tools Division, said the product, named Silverlight, is a browser plug-in that allows Web content providers to offer rich video and interactive media experience from directly within Web sites.

The technology, which builds on Vista's new graphics framework Windows Presentation Foundation (WPF), will be revealed at the US National Association of Broadcasters (NAB) conference, being held this week in Las Vegas.

Microsoft also will unveil Web content providers who have signed up to use the technology once it is available, including Akamai Technologies, Brightcove, Eyeblaster, Major League Baseball and Netflix.

Key said Microsoft is targeting three core audiences with Silverlight, formerly code-named WPF/E: content providers that want to distribute video and rich media over the Web; designers and developers that are building rich interactive applications; and end users that want the best possible experience when viewing Web-based media.

Silverlight is compatible with a range of browsers, including Internet Explorer (IE), Safari and Firefox. As demonstrated by Key, the technology delivers a similar user experience on both IE 7 running on Windows Vista and Firefox running on an Apple Macintosh computer. In fact, a big benefit of the technology for end users is that they will not have to download different video player technology to view online media based on what OS they are running, Key said.

Microsoft is highlighting the video-delivery capabilities of Silverlight at NAB, but the company plans to show how companies can use Silverlight in a similar way to Adobe's Flash to deliver Web-based applications that use animation and other rich media, Key said.

Microsoft also plans to optimise other components of its software platform to add value to Silverlight. For example, the forthcoming Windows Server, code-named Longhorn, will include as a plug-in the IIS7 Media Pack, which adds new features to enhance and reduce the cost of delivering rich media over the Web.

Microsoft's Expression toolset to build rich Internet applications -- which Microsoft is pitting as an alternative to Adobe's recently released Creative Suite 3 -- also is key to Silverlight because designers will use it to create application to be delivered through the technology. Expression should be generally available in June.

Microsoft will deliver a beta of Silverlight at its MIX 2007 conference at the end of April, and will announce plans for general availability at that time, Key said.
