Real-Time Transport 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.
