Silverlight 3 Arrives, Brings Smoother Video, Better Web Apps
Microsoft has released the latest version of its Silverlight player.
The release of Silverlight 3 arrived late Thursday night. The company’s presentation technology for graphics and video on the web was supposed to be released to the public on Friday morning, July 10 — there’s even a lavish launch event scheduled at a San Francisco hotel — but Microsoft decided to push Silverlight out a day early.
Silverlight 3 is a small, free plug-in download from Microsoft. It’s cross-browser and cross-platform, so it runs on Windows, Mac (the newest versions are Intel only) and Linux computers. The open-source Linux version is called Moonlight, and it ships with Novell distributions. If you’re running Ubuntu or some other non-Novell distribution, you can download it and install it manually.
Silverlight is Microsoft’s plug-in based player for streaming video and audio content, handling rich internet apps and displaying animated user interfaces in the browser — Redmond’s answer to Adobe Flash and open-source technologies like those promised by HTML 5. When Silverlight first arrived in 2007, it didn’t run too well on non-Windows desktops. Worse, with very little content available on the web for Silverlight to play, there wasn’t much of a reason to bother with it.
But quite a bit has changed in two years. Most notably, the compelling content finally arrived. Microsoft streamed live video and highlight clips on NBC’s official Beijing Olympics website in the summer of 2008 using Silverlight. The company released version 2 in September of 2008, an upgrade which improved Silverlight’s performance on Macs and improved the video playback quality overall. Silverlight was used again to stream coverage of the 2008 Democratic National Convention and all of the NCAA March Madness basketball tournament games in 2009, serving to raise Silverlight’s profile — and it’s install base — even more.
By now, Silverlight is installed on around 30% of web-connected PCs and devices like Windows Mobile smartphones. It’s a far cry from Adobe Flash’s install base (which is over 90%) but it’s a significant gain in a short period of time nonetheless. Also, Microsoft claims there are over 300,000 developers actively building web sites, apps and animated user interfaces in Silverlight right now.
Silverlight’s video capabilities have always been impressive when compared to Flash, and the new version boasts some new features that should keep the competition with Flash hot. It uses a media broadcasting technology Microsoft calls Smooth Streaming, an adaptive technology for playing the same H.264 video stream at the highest bitrate the device and its bandwidth limitations will allow. So if you’ve got a fast computer with an HD monitor and a wide open pipe, you’ll see super high quality video at up to full 1080p HD. If you’ve got a dinky smartphone with mid-level data service, you’ll see a constrained version of the same video.
The new version of Silverlight also has better 3-D graphics support and the ability to offload graphics work to a GPU for a smoother, hardware-accelerated user experience.
On the rich internet apps front, Silverlight 3 includes the ability for developers to create apps that run outside of the browser on a PC desktop, or on a mobile phone — yet another place where Silverlight 3 is catching up to competing technologies like AIR, Adobe’s Flash-based runtime for running webapps outside of the browser.
Also due to be released Friday (but not showing up yet, as of this writing late Thursday night) is Expression Studio 3, Microsoft’s set of tools for building Silverlight apps, standards-based websites and vector graphics for the web. The current version, Expression Studio 2, costs $700, or $350 for an upgrade from previous versions.
As mentioned previously, the Silverlight browser plug-in is free.
