    2. Session EX32 Smooth Streaming Live in HD: From Camera to Screen The Olympics video team offers you a rare chance to witness an HD production set up, step-by-step, from scratch. Starting with an HD camera, we push the signal through an encoder with a tuned Smooth Streaming configuration, into Internet Information Services (IIS) 7.0, and then out through a Microsoft Silverlight 4 player using File | New and the Silverlight Media Framework. See the same techniques behind Sunday Night Football and the 2010 Winter Olympics, only on a smaller scale. This is a one-of-a-kind session including specialized hardware; not to be missed if you're curious about HD Internet broadcast.

    3. Smooth Streaming “Hello World” Setup the shot Setup the IIS 7.5 Server Setup the video encoder Build a video player in Visual Studio

    4. What’s On Stage? Camera, connected to a Video encoder, connected to a IIS 7.5, connected to a CDN, connected to a Vertigo video player, inside My browser

    5. What is HD? Frame Size 1280 x 720, or 1920 x 1080 Scanning System Progressive or Interlaced Frame Rate 24 or 30 fps 720p30

    6. What is HD

    7. Video Acquisition and Encoding Acquire the video source Convert signal to a connection type that the Inlet encoder supports Preview window on the encoder Profile preset on the encoder to do IIS Smooth Streaming • IIS ingest server • IIS 7.5 with IIS Media Services 3.0 • IIS Publishing Point • Pick the bitrates on the encoder • Alex’s Smooth Streaming calculator • 16:9 (divisible by 16) Pick the “in page” player size Start encoder

    8. Silverlight 4 Player Development Writing a simple Video Player using the SMF Wire up the manifest URL Hit F5 and run the player • Watching the live audience (with a 6 delay second) SMF sites on top of the Microsoft Smooth Streaming Media Element • Available at CodePlex(http://smf.codeplex.com) • SMF opens in Expression Blend • SMF 1.1 out now and 2.0 coming soon • Support for Progressive and Adaptive Streaming

    11. HOOK UP ENCODER

    12. Smooth Streaming Multi-Bitrate Calc

    13. Video Window Size Divisible by 16 for optimal path on the encoding algorithm

    18. SMF v2 – Step 1: Add Assemblies

    19. SMF v2 – Step 2: config.xml <?xmlversion="1.0"encoding="utf-8" ?> <LiveSmoothStreamingSettings> <BufferingEngineSettings ForceAccurateSeeks="true" LiveBufferTimeMilliseconds= "16000" /> <HeuristicsEngineSettings SwitchingFrequencyChunksBeforeUpgrade= "2" SwitchingFrequencyStepSizeForUpgrade="3" WindowSizeHeuristicsMinimumPercentageOfNextLargestTrack= "0.8" FrameRateHeuristicsSuspendTrackIfMoreThanXPercentDroppedFrames= "0.30" FrameRateHeuristicsFlushBufferIfMoreThanXPercentDroppedFrames= "0.40“ FrameRateHeuristicsSuspendNextLowestTrackIfMoreThanXPercentDroppedFrames= "0.50" /> </LiveSmoothStreamingSettings>

    20. SMF v2 – Step 3: Add Namespaces xmlns:smf="clr-namespace:Microsoft.SilverlightMediaFramework;assembly=Microsoft.SilverlightMediaFramework" xmlns:smf_Media="clr-namespace:Microsoft.SilverlightMediaFramework.Media;assembly=Microsoft.SilverlightMediaFramework.Media"

    21. SMF v2 – Step 4: Add Code <smf:Player d:LayoutOverrides="Height"> <smf:Player.Playlist> <smf_Media:Playlist> <smf_Media:Playlist.Items> <smf_Media:PlaylistItemDeliveryMethod="AdaptiveStreaming"MediaSource="http://server/mix10.isml/Manifest"/> </smf_Media:Playlist.Items> </smf_Media:Playlist> </smf:Player.Playlist> </smf:Player>
