Editing Real-time Transport Protocol (section)

==Application design==
A functional multimedia application requires other protocols and standards used in conjunction with RTP. Protocols such as SIP, [[Jingle (protocol)|Jingle]], RTSP, [[H.225]] and [[H.245]] are used for session initiation, control and termination. Other standards, such as H.264, MPEG and H.263, are used for encoding the payload data as specified by the applicable RTP profile.<ref name="perkins_11">{{harvnb|Perkins|2003|pp=11–13}}</ref>

An RTP sender captures the multimedia data, then encodes, frames and transmits it as RTP packets with appropriate timestamps and increasing timestamps and sequence numbers. The sender sets the ''payload type'' field in accordance with connection negotiation and the RTP profile in use. The RTP receiver detects missing packets and may reorder packets. It decodes the media data in the packets according to the payload type and presents the stream to its user.<ref name="perkins_11"/>
