The Real-time Transport Protocol (RTP) specifies a general-purpose data format and network protocol for transmitting digital media streams on Internet Protocol (IP) networks. The details of media encoding, such as signal sampling rate, frame size and timing, are specified in …

2025年3月17日 · The clock rate and number of channels shown here are the normal values for those payload formats that have a normal value. Both type and subtype names are case-insensitive as defined in [ RFC6838 ]. This registry has been closed; it was considered redundant because all RTP payload formats are part of the [ IANA registry media-types ].

RTP is designed for end-to-end, real-time transfer of streaming media. The protocol provides facilities for jitter compensation and detection of packet loss and out-of-order delivery, which are common, especially during UDP transmissions on an IP network. RTP allows data transfer to multiple destinations through IP multicast. [3] .

2022年1月10日 · 和rtp相关的协议有两个rfc, 分别是. RFC 3550是对RFC 1889的稍微改进，然而大体上是没什么改变的。 所以我们可以直接看RFC 3550。 Synchronization source (SSRC): The source of a stream of RTP packets, identified by a 32-bit numeric SSRC identifier carried in the RTP header so as not to be dependent upon the network address.

When an RTP packet is received from a participant whose SSRC is not in the sender table, the SSRC is added to the table, and the value for senders is updated. For each compound RTCP packet received, the value of avg_rtcp_size is updated: avg_rtcp_size = (1/16) * packet_size + (15/16) * avg_rtcp_size where packet_size is the size of the RTCP ...

2022年12月8日 · A protocol is designed to handle real-time traffic (like audio and video) of the Internet, is known as Real Time Transport Protocol (RTP). RTP must be used with UDP. It does not have any delivery mechanism like multicasting or port numbers. RTP supports different formats of files like MPEG and MJPEG.

Real-Time Transport Protocol (RTP) session. An SSRC value is part of an RTP packet header, as described in [RFC3550]. Transmission Control Protocol (TCP): A protocol used with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. TCP handles keeping

2025年3月10日 · Real-Time Transport Protocol (RTP) is a network communication protocol developed on the User Datagram Protocol (UDP), which helps transport audio, video, and media traffic in real-time while minimizing jitter and packet loss. This article explains how RTP works, its critical applications, and associated protocols like RTCP and RTSP.

Many aspects of RTP and the VAT protocol are similar, but RTP improves upon the VAT protocol in a number of ways: The VAT protocol was designed for audio only, while RTP is specified for audio and video and may be suitable for other real-time applications.

This object represents a Rtp value and provides utility methods to retrieve the object represenations for the various types of Rtps such as Member, Members, DateAsNumber, Member Range etc. Not all methods are available for all types of Rtps.
