Examples

The following example shows how to create a MediaProtectionManager, set the Properties property, and add event listeners for ComponentLoadFailed and ServiceRequested.

private void InitMediaProtectionManager()
{
   mediaProtectionManager = new Windows.Media.Protection.MediaProtectionManager();
   mediaProtectionManager.ServiceRequested += MediaProtectionManager_ServiceRequested;
   mediaProtectionManager.ComponentLoadFailed += MediaProtectionManager_ComponentLoadFailed;
   mediaProtectionManager.RebootNeeded += MediaProtectionManager_RebootNeeded;
}



private void MediaProtectionManager_RebootNeeded(MediaProtectionManager sender)
{
   LogMessage("Reboot Required");
}

private void MediaProtectionManager_ComponentLoadFailed(MediaProtectionManager sender, ComponentLoadFailedEventArgs e)
{
   LogMessage(e.Information.Items.Count.ToString() + " failed components");
   LogMessage("<h2>Components:</h2>");

   //  List the failing components
   for (var i = 0; i < e.Information.Items.Count; i++)
   {
         LogMessage("<h3>" + e.Information.Items[i].Name + "</h3>" +
               "<p>Reasons=0x" + e.Information.Items[i].Reasons.ToString() +
               "<p>Renewal Id=" + e.Information.Items[i].RenewalId);
   }

   e.Completion.Complete(true);
}

private void MediaProtectionManager_ServiceRequested(MediaProtectionManager sender, ServiceRequestedEventArgs e)
{
   LogMessage("Got Enabler - system/type: {" + e.Request.ProtectionSystem + "}/{" + e.Request.Type + "}");
   e.Completion.Complete(true);
}

Remarks

The MediaProtectionManager can be passed to the media playback infrastructure in either of two ways:

• As an attribute for a <video> or <audio> tag using the msSetMediaProtectionManager method.
• Directly to a media playback API. The MediaProtectionManager object is notified of content enabler objects. These objects must be processed by the application, to establish access to protected content. Each MediaProtectionManager object is associated with a single instance of playback.

Constructors

MediaProtectionManager()

Initializes a new instance of the MediaProtectionManager class.

Properties

Properties

Gets a PropertySet object containing any properties attached to the protection manager.

Events

ComponentLoadFailed	Fires when the load of binary data fails.
RebootNeeded	Fires when a reboot is needed after the component is renewed.
ServiceRequested	Fires when a service is requested.
