>I need to transmit data

What kind of data is this?  You cannot just transmit data using RTP 
without knowing what kind of data it is.  Each media type has a 
different "RTP paayload format" - i.e., rules for how the data is 
packaged into RTP packets.

"PassiveServerMediaSession" is used to provide access to streams 
(typically multicast) that already 
exist.  "OnDemandServerMediaSession" creates a new (unicast) stream 
for each new client.

No - "testRelay" does not use RTSP at all.  It simply relays UDP packets.
