Remarks

Previous releases of the PlayReady API required callers to hard-code a well-known string and GUID in their code. These APIs provide those values to the caller so they can request them rather than hard-coding them.

In the MediaProtectionManager.Properties property (a PropertySet object), the "Windows.Media.Protection.MediaProtectionSystemIdMapping" string maps to another PropertySet. This in turn will typically have the string "Windows.Media.Protection.PlayReady.PlayReadyStatics.MediaProtectionSystemId" map to Windows.Media.Protection.PlayReady.PlayReadyStatics.InputTrustAuthorityToCreate.

MediaProtectionManager protectionManager = new MediaProtectionManager();
protectionManager.Properties.Add(
    "Windows.Media.Protection.MediaProtectionContainerGuid", 
    PlayReadyStatics.ProtectionSystemId.ToString());
Windows.Foundation.Collections.PropertySet cpSystems = 
    new Windows.Foundation.Collections.PropertySet();
cpSystems.Add(
    PlayReadyStatics.MediaProtectionSystemId.ToString(), 
    PlayReadyStatics.InputTrustAuthorityToCreate);
