NAB - Microsoft unveils Silverlight as Flash killer

NAB - Microsoft unveils Silverlight as Flash killer

New technology delivers rich media applications on the Web

Microsoft this week will reveal new technology to deliver rich media applications on the Web, part of a broader strategy to go head-to-head with Web and design tools powerhouse, Adobe Systems.

As described by Forest Key, a director of product management for Microsoft's Server and Tools Division, Silverlight is a browser plug-in that allows Web content providers to offer a rich video and interactive media experience from directly within Web sites. The technology, which leverages Vista's new graphics framework, Windows Presentation Foundation (WPF), will debut at the 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 was 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 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 would not have to download different video player technology to view online media based on what OS they were running, Key said.

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

Microsoft 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 -- is also key to Silverlight because designers will use it to create application to be delivered through the technology. Expression should be generally available in June.

IT developer and analyst for ProAssurance, Keith Cutcliffe, is skeptical that Microsoft will ever gain the faithful user base Adobe has. However, he said that enterprise customers that had developed Flash applications to run on Microsoft-based Web infrastructure eventually might use Silverlight and Expression instead because of the underlying back-end platform ties.

CEO of application development firm Vertigo Software, Scott Stanfield, seems supportive of that sentiment. He said Silverlight filled a major gap in Microsoft's strategy to provide a mechanism to deliver and build applications that provided the stability of desktop applications with the user experience of media-rich Web applications.

"Previously Flash was the only answer," he said. "Now Silverlight becomes a viable alternative."

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

In Pictures: Houston, we have a bug - 9 famous software glitches in space

There’s never a good time to run into software bugs, but some times are worse than others - like during a mission to space. Spacecraft of all shapes and sizes rely heavily on software to complete their objectives. But those missions can be quickly ended by the simplest of human errors when writing code. The omission of an overbar here or overflow error checking code there can mean the difference between success or failure, not to mention the loss of hundreds of millions of dollars, years of work and, on manned missions, human life. Use the arrows above to read about 9 examples that show that, despite the care with which these systems are built, bugs have occurred in spacecraft software since we started to fling rockets into space - and will, no doubt, continue to crop up.
