Das gegenüber dem RTP um Sicherheitsfunktionen erweiterte SRTP (Secure Real-Time Transport Protocol) besitzt den Vorteil einer zusätzlichen. Seit ist RTP im RFC spezifiziert. Das Real Time Transport Protocol ist in der Lage, Multimediadatenströme wie Audio oder Video zu kodieren, in Pakete. Der Internet-Protokollstandard Real-Time Transport Protocol (RTP) wurde für die Echtzeitübertragung von Multimediadaten konzipiert.
RTP und SRTP – was steckt hinter den beiden Protokollen?Die Übertragung läuft über das RTP-Protokoll (Real-Time Protocol, siehe RFC ), welches auf UDP basiert. RTP Audio unterstützt dabei sowohl IPv4 als auch. Greifen Sie mit Ihrer RTP Play-App auf über 20 Live-Übertragungen und Tausende von Inhalten zu. Mit RTP Play können Sie: Programme, Kanäle und. RTCP (Real-Time Control Protocol) zusammen. Typische Anwendungen von RTP sind die VoIP-Telefonie oder IP-basierte Videokonferenzen.

For example, loss of a packet in audio application may result in loss of a fraction of a second of audio data, which can be made unnoticeable with suitable error concealment algorithms.
RTP is used in conjunction with other protocols such as H. The data transfer protocol, RTP, carries real-time data.
Information provided by this protocol includes timestamps for synchronization , sequence numbers for packet loss and reordering detection and the payload format which indicates the encoded format of the data.
RTP sessions are typically initiated between communicating peers using a signaling protocol, such as H. These protocols may use the Session Description Protocol to specify the parameters for the sessions.
An RTP session is established for each multimedia stream. Audio and video streams may use separate RTP sessions, enabling a receiver to selectively receive components of a particular stream.
Applications most typically use UDP with port numbers in the unprivileged range to RTP is designed to carry a multitude of multimedia formats, which permits the development of new formats without revising the RTP standard.
To this end, the information required by a specific application of the protocol is not included in the generic RTP header. For each class of application e.
The profile defines the codecs used to encode the payload data and their mapping to payload format codes in the protocol field Payload Type PT of the RTP header.
Each profile is accompanied by several payload format specifications, each of which describes the transport of particular encoded data.
RTP packets are created at the application layer and handed to the transport layer for delivery. The RTP header has a minimum size of 12 bytes.
After the header, optional header extensions may be present. This is followed by the RTP payload, the format of which is determined by the particular class of application.
A functional multimedia application requires other protocols and standards used in conjunction with RTP. Other standards, such as H.
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. From Wikipedia, the free encyclopedia.
