+    \class QMediaService
+    \brief The QMediaService class provides a common base class for media
+    service implementations.
+    \ingroup multimedia-serv
+    \preliminary
+    \since 4.7
+
+    Media services provide implementations of the functionality promised
+    by media objects, and allow multiple providers to implement a QMediaObject.
+
+    To provide the functionality of a QMediaObject media services implement
+    QMediaControl interfaces.  Services typically implement one core media
+    control which provides the core feature of a media object, and some
+    number of additional controls which provide either optional features of
+    the media object, or features of a secondary media object or peripheral
+    object.
+
+    A pointer to media service's QMediaControl implementation can be
+    obtained by passing the control's interface name to the control() function.
+
+    \code
+    QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
+            service->control("com.nokia.Qt.QMediaPlayerControl/1.0"));
+    \endcode
+
+    Media objects can use services loaded dynamically from plug-ins or
+    implemented statically within an applications.  Plug-in based services
+    should also implement the QMediaServiceProviderPlugin interface.  Static
+    services should implement the QMediaServiceProvider interface.
+
+    \sa QMediaObject, QMediaControl, QMediaServiceProvider, QMediaServiceProviderPlugin
