Real-Time Transport Protocol RTP <protocol> (RTP) An {Internet} {protocol} for transmitting {real-time} data such as {audio} and {video}. RTP itself does not guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support {streaming} data. Typically, RTP runs on top of the {UDP} protocol, although the specification is general enough to support other {transport protocols}. RTP has received wide industry support. {Netscape} intends to base its {LiveMedia} technology on RTP, and {Microsoft} claims that its {NetMeeting} product supports RTP. (2003-07-06)
