+ * <para>
+ * RTSP supports transport over TCP or UDP in unicast or multicast mode. By
+ * default rtspsrc will negotiate a connection in the following order:
+ * UDP unicast/UDP multicast/TCP. The order cannot be changed but the allowed
+ * protocols can be controlled with the "protocols" property.
+ * </para>
+ * <para>
+ * rtspsrc currently understands SDP as the format of the session description.
+ * For each stream listed in the SDP a new rtp_stream%d pad will be created
+ * with caps derived from the SDP media description. This is a caps of mime type
+ * "application/x-rtp" that can be connected to any available rtp depayloader
+ * element. 
+ * </para>
+ * <para>
+ * rtspsrc will internally instantiate an RTP session manager element
+ * that will handle the RTCP messages to and from the server, jitter removal,
+ * packet reordering along with providing a clock for the pipeline. 
+ * This feature is however currently not yet implemented.
+ * </para>
+ * <para>
