[B]Smooth Streaming for IIS 7.0 - Managing Your Presentations [/B]


[LIST][*]Author: John Bocharov[/LIST]

The Smooth Streaming extension for [URL="http://go.microsoft.com/?linkid=9652406"]Internet Information Services (IIS) 7.0[/URL] allows you to set up a Web server as a Smooth Streaming server with a default [URL="http://go.microsoft.com/?linkid=9652120"]Microsoft Silverlight 2.0[/URL] client implementation and sample content, and to manage your content using IIS Manager. This document covers the following scenarios:

[B]Prerequisites[/B]

The scenarios in this article require a Smooth Streaming server. Follow the steps in [URL="http://learn.iis.net/page.aspx/558/smooth-streaming-for-iis-70---getting-started/"]Smooth Streaming for IIS 7.0 - Getting Started[/URL] to set up a Smooth Streaming server and deploy the Smooth Streaming sample content.
[B]Viewing the Tracks in a Smooth Streaming Presentation[/B]

The [B]Smooth Streaming Presentations[/B] page in IIS Manager is useful for displaying the Smooth Streaming presentation files in a directory at a glance. To open the [B]Smooth Streaming Presentations[/B] page in IIS Manager, do the following:

[LIST][*]In the [B]Connections[/B] pane, click the directory where you deployed the sample content, and then in the [B]Features View[/B] pane, under [B]Media Services[/B], double-click the [B]Smooth Streaming Presentations[/B] icon.

As highlighted below, the [B]Smooth Streaming Presentations[/B] page displays a summary of the video and audio bit rates available for each presentation.

[B]Cloning a Smooth Streaming Presentation[/B]

To clone a Smooth Streaming presentation, select a presentation in the [B]Smooth Streaming Presentations[/B] page (described in the [URL="http://learn.iis.net/page.aspx/569/smooth-streaming-for-iis-70---managing-your-presentations#tracks"]previous section[/URL]), and then in the [B]Actions[/B] pane, click [B]Clone[/B].
[URL="http://learn.iis.net/file.axd?i=1558"][IMG]http://learn.iis.net/file.axd?i=1558[/IMG][/URL]
In the [B]Clone Presentation[/B] dialog box, enter a new name for the cloned presentation, (for example, [B]Big Buck Bunny - Limited[/B]), and then click [B]OK[/B].
[URL="http://learn.iis.net/file.axd?i=1559"][IMG]http://learn.iis.net/file.axd?i=1559[/IMG][/URL]
The cloned presentation is displayed in the [B]Smooth Streaming Presentations[/B] page.

Cloning creates a version of a presentation that shares the presentation metadata without making a deep-copy of the media (.ismv) files. You can observe this behavior by selecting the [B]Content View[/B] tab for the presentation in IIS Manager. The following figure shows that .ism and .ismc files have been created for the cloned presentation, and that the original and cloned presentations share the same set of media files.
[URL="http://learn.iis.net/file.axd?i=1561"][IMG]http://learn.iis.net/file.axd?i=1561[/IMG][/URL]
To view the cloned presentation, do the following:

[LIST=1][*]Navigate your Web browser to [URL]http://localhost/Big_Buck_Bunny/Default.html[/URL].

[B]Note[/B] If you stored the sample content in a different content directory, substitute its URL for [B]Big_Buck_Bunny[/B]. To view the content from a remote computer, substitute the server’s URL for [B]localhost[/B].[*]In [B]Presentation Name[/B], enter [B]Big Buck Bunny – Limited[/B].[*]In [B]Silverlight Player[/B], select [B]User Experience Simulator[/B].

[B]Saving Bandwidth Costs by Limiting the Maximum Bit Rate[/B]

After you clone a presentation (described in the [URL="http://learn.iis.net/page.aspx/569/smooth-streaming-for-iis-70---managing-your-presentations#clone"]previous section[/URL]), notice the highest bit rate value in the [B]Bit Rate History[/B] panel in the Silverlight User Experience Simulator.
[URL="http://learn.iis.net/file.axd?i=1563"][IMG]http://learn.iis.net/file.axd?i=1563[/IMG][/URL]
You can save bandwidth by removing the highest available bit rate for the presentation in IIS Manager. To do this, do the following:

[LIST=1][*]In the [B]Connections[/B] pane, click the directory where you deployed the sample content, and then in the [B]Features View[/B] pane, under [B]Media Services[/B], double-click the [B]Smooth Streaming Presentations[/B] icon.
[IMG]http://learn.iis.net/file.axd?i=1796[/IMG][*]In the [B]Smooth Streaming Presentations[/B] page, select the [B]Big Buck Bunny - Limited.ism[/B] presentation, and then, in the [B]Actions[/B] pane, click [B]Edit Smooth Stream[/B].
[URL="http://learn.iis.net/file.axd?i=1564"][IMG]http://learn.iis.net/file.axd?i=1564[/IMG][/URL][*]In the [B]Smooth Streaming Presentation[/B] page that appears, perform the following actions to remove the highest bit rate from the presentation:

a. Select the video track with the highest bit rate value ([B]2436000[/B]).
b. Click [B]Remove[/B].
c. In the [B]Actions[/B] pane, click [B]Apply[/B].
[URL="http://learn.iis.net/file.axd?i=1565"][IMG]http://learn.iis.net/file.axd?i=1565[/IMG][/URL][*]Navigate your Web browser to [URL]http://localhost/Big_Buck_Bunny/Default.html[/URL].
[B]Note[/B] If you stored the sample content in a different content directory, substitute its URL for [B]Big_Buck_Bunny[/B]. To view the content from a remote computer, substitute the server’s URL for [B]localhost[/B].[*]In [B]Presentation Name[/B], enter [B]Big Buck Bunny - Limited[/B].[*]In [B]Silverlight Player[/B], select [B]User Experience Simulator[/B].
[URL="http://learn.iis.net/file.axd?i=1562"][IMG]http://learn.iis.net/file.axd?i=1562[/IMG][/URL][*]Verify that the highest bit rate value in the [B]Bit Rate History[/B] panel in the Silverlight User Experience Simulator is lower.[URL="http://learn.iis.net/file.axd?i=1567"]
