Microsoft is adding iPhone compatibility to Silverlight and has already demonstrated the technology. No modifications to Safari are necessary, as the software will send video in an iPhone-compatible H.264 stream just like YouTube and other streaming sites do currently.
Content providers will have the option of making their Silverlight streaming video iPhone-compatible now that Microsoft has added the feature on the server side.
Silverlight was released in April of 2007. The product is often compared to Adobe Flash, as it allows the same content to be viewed over the web regardless of browser, operating system or platform.
Apple has not allowed Adobe Flash to run on the iPhone. Reports have indicated Apple is concerned about the performance of Flash on the iPhone and heavy demand on the internal battery.Netflix is one company that uses Silverlight to stream on-demand movies to subscribers via their broadband connection.
