Since the RTP is suitable for real-time data transmission in multimedia services like VoD, AoD, and VoIP, it has been adopted as a real-time transport protocol by RTSP, H.323, and SIP. Even though the RTP protocol stack for embedded systems has been in great need for efficient support of multimedia services, such a stack has not been developed yet. In this paper, we explain
embeddedRTP
which supports the RTP protocol stack at the kernel level so that it is suitable for embedded systems. Since
embeddedRTP
is designed to reside in the UDP module, existing applications which rely on TCP/IP services can be processed the same as before, while applications which rely on the RTP protocol stack can request RTP services through
embeddedRTP
’s API. Our performance test shows that packet-processing speed of
embeddedRTP
is about 7.8 times faster than that of UCL RTP for multimedia streaming services on PDA in spite that its object code size is reduced about by 58% with respect to UCL RTP’s.
