+BlueZ D-Bus Media API description
+*********************************
+
+Media hierarchy
+===============
+
+Service		org.bluez
+Interface	org.bluez.Media
+Object path	[variable prefix]/{hci0,hci1,...}
+
+Methods		void RegisterEndpoint(object endpoint, dict properties)
+
+			Register a local end point to sender, the sender can
+			register as many end points as it likes.
+
+			Note: If the sender disconnects the end points are
+			automatically unregistered.
+
+			possible properties:
+
+				string UUID:
+
+					UUID of the profile which the endpoint
+					is for.
+
+				byte Codec:
+
+					Assigned mumber of codec that the
+					endpoint implements. The values should
+					match the profile specification which
+					is indicated by the UUID.
+
+				array{byte} Capabilities:
+
+					Capabilities blob, it is used as it is
+					so the size and byte order must match.
+
+		void UnregisterEndpoint(object endpoint)
+
+			Unregister sender end point.
+
+MediaEndpoint hierarchy
+=======================
+
+Service		unique name
+Interface	org.bluez.MediaEndpoint
+Object path	freely definable
+
+Methods		void SetConfiguration(object transport, array{byte} configuration)
+
+			Set configuration for the transport.
+
+		array{byte} SelectConfiguration(array{byte} capabilities)
+
+			Select preferable configuration from the supported
+			capabilities.
+
+			Returns a configuration which can be used to setup
+			a transport.
+
+			Note: There is no need to cache the selected
+			configuration since on success the configuration is
+			send back as parameter of SetConfiguration.
+
+		void ClearConfiguration()
+
+			Clear any configuration set.
+
+MediaTransport hierarchy
+========================
+
+Service		org.bluez
+Interface	org.bluez.MediaTransport
+Object path	[variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX/fdX
+
+Methods		dict GetProperties()
+
+			Returns all properties for the interface. See the
+			properties section for available properties.
+
+		fd Acquire(string accesstype)
+
+			Acquire transport file descriptor.
+
+			possible accesstype:
+
+				"r" : Read only access
+
+				"w" : Write only access
+
+				"rw": Read and write access
+
+		void Release(string accesstype)
+
+			Releases file descriptor.
+
+		void SetProperty(string name, variant value)
+
+			Changes the value of the specified property. Only
+			properties that are listed a read-write are changeable.
+			On success this will emit a PropertyChanged signal.
+
+Signals		void PropertyChanged(string name, variant value)
+
+			This signal indicates a changed value of the given
+			property.
+
+Properties	uint16 Delay [readwrite]
+
+			Optional. Transport delay in 1/10 of milisecond, this
+			property is only writeable when the transport was
+			acquired by the sender and the sender is a sink.
+
+		boolean NREC [readwrite]
+
+			Optional. It tells if echo cancelling and noise
+			reduction functions are active in the transport, this
+			property is only writeable when the transport was
+			acquired by the sender.
+
+		object Device [readonly]
+
+			Device object which the transport is connected to.
