  6. 6. Media Delivery Mechanisms<br />Two most-common audio/video delivery mechanisms...<br />Streaming<br />Progressive <br />Download<br />Simple send-and-forget HTTP delivery of an audio/video file that starts to play after a few seconds of downloading<br />Actively-controlled transfer of a/v content typically received in near- real-time by the client and then discarded after rendering<br />Scenario: You are hosting Web sites and want to add rich media experiences<br />Scenario: You want to deliver media to mobile devices or for live events, such as baseball games<br />

Notas do Editor

  • These are the primary media delivery scenarios for which WMS and IIS are focused on providing great features.
  • Microsoft provides great products for the primary media workflow, from encoding to delivery to consumption.
  • Peer-to-peer is not specifically called out on this slide – for the purposes of this discussion, peer-to-peer solutions (e.g. BitTorrent DNA, Abacast, Kontiki) have similarity or overlap with CDNs. UGC = User-Generated ContentCDN = Content Delivery Network (also referred to as Content Distribution Network)ASP = Application Service ProviderDIY = Do It YourselfThis presentation is primarily focused on the DIY customer.
  • These definitions set the context for discussing Microsoft media server offerings.
  • At a basic network transaction level, here is what streaming looks like.Client asks for information about the mediaServer provides infoClient asks server to set up delivery for two of the streams (e.g. Video and English-language audio)Server acknowledgesClient requests mediaServer delivers mediaServer and client talk throughout the delivery
  • Standard Progressive Download is much simpler. The client says “Give me media,” and the server sends it down as fast as possible, with no further discussion.
  • Windows Server 2008 provides two great options for media delivery:Windows Media Services 2008, an advanced streaming serverIIS Media Pack, which provides advanced progressive download features
  • WMS 2008 provides a great value proposition, as we’ll talk about in the following slides…
  • WMS is in use at most CDNs and more than half of the enterprises around the world.Customers tell us that WMS is 2-4x more scalable that Real Helix, Apple QuickTime, and Adobe Flash Media ServerWMS has been used for some of the largest Web events, such as the 300,000 concurrent users watching the “Return to Space” launch of the U.S. space shuttle, and the upcoming NBC coverage of the Summer 2008 Olympics
  • Dual Intel Xeon 3.0 GHz processors2 GbE NICs with TOE support 4 GB RAMTwo or more 15k+ SCSI hard drivesServer Core adds 10-25% more scalability _on top_ of these numbers
  • Now let’s look at the latest media serving technology being developed…
  • The Media Pack is a set of IIS extensions. Like all IIS7 functionality, we simply built new modules using the extendable IIS7 architecture.
  • The green bar represents data being downloaded on a media player. The key here is that if a broadband end user drops off after only watching 20% of the content, you still paid to download 100% of it by using standard progressive download.
  • With Bit Rate Throttling, you only pay to deliver a little extra data if an end user doesn’t watch the whole file, typically 10 seconds worth.
  • When enabled,Bit Rate Throttling automatically detects, bursts, and then throttles eleven media file types. You can also add additional media formats through the configuration file. Bit Rate Throttling works just as well for non-media, or data, file types, such as large database or PowerPoint files. You can also throttle based on MIME types.
