4. What do Web Hosting Companies Need to Know? 1.Media Formats 2.Streaming vs. Progressive Download 3.MIME Types 4.Integrating with Web Analytics 5.Integrating with Content Delivery Networks (CDNs) 6.Additional Services around RIA Construction

5. Media Formats: Video WMV1: Windows Media Video 7 WMV2: Windows Media Video 8 WMV3: Windows Media Video 9 WMVA: Windows Media Video Advanced Profile, non-VC-1 WMVC1: Windows Media Video Advanced Profile, VC-1 + Multiple Bit Rate (MBR)

6. Media Formats: Audio WMA 7: Windows Media Audio 7 WMA 8: Windows Media Audio 8 WMA 9: Windows Media Audio 9 MP3: ISO/MPEG Layer-3 – see Silverlight SDK for additional detail

7. Media Formats: Encoding Use Expression Encoder – Has command-line interface so it can be scripted as part of a media workflow – Encode from.3g2.mod.3gp.mov.asf.mp4.avi.mpeg.dv.mpg.dvr-ms.ts.m2v.vob.m4v.wmv.aiff.m4A m4B bwf mp3 wav wma – Use Windows Media Encoder Use any other encoder that creates supported formats

8. Streaming vs. Progressive Download Progressive Download – Put a media file on any server – vanilla hosting – Can only view content that’s been download so far – Cannot monitor consumption from server Streaming – On demand/live media – Can monitor consumption from server – Windows Media Server – IIS Add-on – Random-access: Can fast forward/move around content immediately

9. MIME Types You must at the MIME type for XAML to the website configuration to support Silverlight. XAML = application/xaml+xml

10. Integrating with Web Analytics Measuring the performance of your website with respect to business goals. Most web analytics services use JavaScript page tags JavaScript page tags can be triggered by Silverlight events Scenarios: – Track user interaction behavior – Track media drop-off with progressive download

11. Web Analytics: User Interaction Analytics can be introduced at any stage of the web development process With compiled RIA formats, analytics must be introduced before design is created. Add Event handlers that then call page tags

12. Web Analytics: Media Drop-Off Use invisible media markers every 5 seconds inserted in media when it is initially loaded. Media markers trigger JavaScript events JavaScript events call page tags

13. Web Analytics: A/B Testing Design in XAML is separated from the code in JavaScript Very easy to try different XAML in controlled tests Upcoming webinar on Silverlight + Web Analytics – Tuesday, Oct 16 2007, 11:00 AM PST – Detail on my blog: http://blogs.msdn.com/synergisthttp://blogs.msdn.com/synergist

14. Integrating with CDNs What should be on CDNs? – Images – Video – Audio What shouldn’t be on CDNs? – XAML – Cross-domain access security issues – Microsoft is working on a solution

15. Additional Services around Silverlight RIA Design & Development using Expression Blend Media Encoding using Expression Encoder Media Storage
