Before going into the detailed structure of RTP, you should know that RTP is basically a combination of two parts -
- Real Time Protocol (RTP): It carries real-time data.
- Real Time Control Protocol (RTCP): It monitors the quality of service and conveys information about the participants.
We will go through RTP first and then discuss RTCP. Both play important roles in the transmission. Here you should note that the data and control messages are separated in the forms of RTP and RTCP.
