RTP (Real-time Transport Protocol) is a protocol for streaming video and audio data over the internet, and other computer networks. It usually runs over UDP.
RTCP (RTP Control Protocol) is a "sister protocol" of RTP. It transmits high-level information used for quality control, statistics, etc.
The term RTP can mean just the main RTP protocol, or it can be an umbrella term for both RTP and RTCP.
