The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. RTP is used in communication and entertainment systems that involve streaming media, such as telephony, video teleconference applications including WebRTC, television services and web-based push-to-talk features.

2022年12月8日 · The transport layer is the fourth layer in the OSI model and the second layer in the TCP/IP model. The transport layer provides with end to end connection between the source and the destination and reliable delivery of the services.

RTP depends upon the lower-layer protocol to provide some mechanism such as ports to multiplex the RTP and RTCP packets of a session. Transport address: The combination of a network address and port that identifies a transport-level …

2024年7月26日 · The Real-time Transport Protocol (RTP), defined in RFC 3550, is an IETF standard protocol to enable real-time connectivity for exchanging data that needs real-time priority. This article provides an overview of what RTP is …

RTP，即real-time transport protocol（实时传输协议），为实时传输交互的音频和视频提供了端到端传输服务。 其中包括载荷的类型确认，序列编码，时间戳和传输监控功能。 一般应用都是基于 UDP协议，来使用RTP的多路技术以及验和服务。 然而，RTP还可以与其它适合的协议并用，如果底层网络支持多路分发，RTP还可以将数据传输给多个目标。 需要注意的是RTP不提供任何机制以保证数据的实时性和 QOS (quality-of-service)，而是依赖底层的服务来提供这些功能，RTP既 …

What is the use of RTCP for two-party calls? How do I register an RTP payload type? What is the current list of RTP payload types? What are dynamic payload types? Do receivers need their own SSRC identifiers? Why can't we just use TCP for audio and video? Can't we just use XTP? How should RTP sessions be played back?

2023年9月9日 · Real-time Transport Protocol (RTP) runs on top of UDP. Specifically, audio or video chunks of data, generated by the sending side of a multimedia application, are encapsulated in RTP packets, and each RTP packet is in turn encapsulated in a UDP segment.

2024年10月19日 · rtp是一种面向数据包的传输协议，设计用于高效传输实时或近实时的音频、视频和其他时间敏感数据。rtp通常与rtcp（实时传输控制协议）一起使用，rtcp负责提供质量反馈、同步信息以及...

The RTP standard actually defines a pair of protocols: R TP and R TCP. RTP is used for the exchange of multimedia data, while RTCP is the control part and is used to periodically obtain feedback control information regarding the quality of transmission associated with the data flows. RTP usually runs over UDP/IP; but efforts are

RTP provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services. RTP does not address resource reservation and does …
