Microsoft has turned on the Silverlight.
Silverlight 1.0, a development platform for delivering audio and video via the Web, was made available yesterday, according to a company press release. It’s aimed at Adobe’s ubiquitous Flash platform.
Silverlight is cross-platform and cross-browser, allowing usage and development on Macs and Linux. Its importance to Microsoft is hinted at by the fact that Microsoft Chief Software Architect Ray Ozzie is quoted in the release.
To make inroads against Flash, Silverlight needs to offer some functionality Flash doesn’t; and it does that in its initial release, offering 720p high-definition video for higher quality. Flash is working on its own version, but hasn’t delivered a product yet that can handle resolution that high.
Microsoft also announced an extension of its growing relationship with Linux vendor Novell. According to the release, Microsoft will deliver Silverlight support for Linux under the name Moonlight. It’s expected to be ready in about six months.
Microsoft first announced Silverlight in April, at the National Association of Broadcasters conference. It hit its timeframe, as final availability was put at Summer 2007. Silverlight, previously called Windows Presentation Foundation Everywhere (WPF/E), is part of the .NET Framework.
Silverlight is a free download from the Microsoft site.
In addition to Silverlight, Microsoft released Expression Encoder 1.0 for designers and multimedia authors. Expression is Silverlight’s built-in encoder.
