RTCP is used for conveying quality information about the RTP
transmission and for communicating an identifier with each RTP
stream that can be used to match up RTP streams that belong to
eachother (like a video with audio, where each is sent as a separate
RTP stream). RTCP is part of the RTP specification and is optional
for unicast, but mandatory for multicast sessions.

RTSP is used for session initiation and simple controls like Start, Stop,
Skip forward, Skip backward etc.

So they suite entirely different purposes.
