The Ehmediastatus.idl file that is included in the Windows Media Center SDK defines the interfaces, structures, and enumeration types that are used by a media status sink component.
Note The Media State Aggregation Service API has been deprecated.
To receive status information from the media state aggregation service (MSAS), a driver or other software component must implement the interfaces below:
| Interface | Description |
| IMediaStatusSession | Passes media status properties to the media status sink. |
| IMediaStatusSink | Initializes the media status sink and creates a media status session. |
A driver or other software component can use the following structures and enumeration types to process media status notifications that are sent to its media status sink:
| Structure or Enumeration Type | Description |
| MEDIASTATUSPROPERTY | Contains a media status property that has changed. |
| MEDIASTATUSPROPERTYTAG | Contains values that identify properties of media status notifications. |
