rtp tutorial

RTP provides an end-to-end network transmission function, suitable for applications that transmit real-time data (multicast or Unicast Network Services), such as audio and video. RTP does not require resource reservation or guarantee the service quality of real-time services. The Data Transmission Control Protocol RTCP is enhanced. This protocol is suitable for monitoring data transmission in large multicas

1. Introductionwith the development of information industry, people's demand for information resources has been gradually transition from text and pictures to audio and video, and more and more emphasis is placed on the real-time and interactivity of acquiring resources. But people are faced with another unavoidable embarrassment of having to spend a lot of time waiting to transfer files while seeing vivid and clear media demonstrations on the web. In order to solve this contradiction, a new med

One, RTP (real-time transmission protocol) The RTP full name is the real-time Transport Protocol (real-time transport protocol), and the RTP protocol is commonly used in streaming media systems (with RTCP protocol or RTSP protocol). Because RTP itself has time stamp, it is used as a formate in FFmpeg. Each

http://blog.csdn.net/heanyu/article/details/6202500 RTP (Real time Transport Protocol) RTP is a transport protocol for multimedia traffic on the Internet that is published by the IETF (Internet Engineering Task Force) as RFC1889 . RTP is defined as a one-to-many transmission, with the purpose of providing time information and implementing stream synchronization

Streaming media transmission, video monitoring, video conferencing, and VoIP are all inseparable from the application of the RTP protocol, but when everyone chooses the RTP protocol based on experience or other people's applications, you may have wondered why we should use RTP for streaming media transmission? Why must we use

Jrtplib is a fully open-source RTP Library developed by EDM (expertise centre for digital media) of Hasselt University in Belgium and implemented in C ++, currently, it can run on Windows, Linux, F

With the rapid development of the Internet, streaming media technology has become more and more widely used. streaming media technology has been used for broadcasting on the internet, playing movies, remote teaching, and online news websites. However, most of the information reported in the existing public documents is the use of the existing Streaming Media Server to build a streaming media service system, or the research on the encoding method of streaming media data. This article focuses on h

Its syntax is as follows: + --------------- +| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |+-+| F | NRI | type |+ --------------- + F: 1 bit.Forbidden_zero_bit. The H.264 specification specifies that this digit must be 0. NRI: 2 bits.Nal_ref_idc. 00 ~ 11. It seems to indicate the importance of

coding standards jointly developed by a Joint Video group (JVT) consisting of the ITU-T video coding Expert Group (VCEG) and the ISO/IEC dynamic image Expert Group (mPEG, its biggest advantage is its high data compression ratio. h. 264 of the compression ratio is more than 2 times of the MPEG-2, is the MPEG-4 of 1.5 ~ 2 times. At the same time, the video encoding layer (VCL) and network extraction layer (NAL) are used.The hierarchical design is very suitable for real-time transmission of stream

-time multimedia transmission. RTP is an application-oriented transport layer protocol that does not provide any guarantee of Transmission reliability and traffic congestion control mechanisms. RTP is located on top of UDP (User datainprotocol. Although UDP is not as reliable as TCP and cannot guarantee the service quality of real-time services, RTCP needs to monitor data transmission and service quality in

Streaming media refers to the continuous time-based media transmitted using stream technology in the network. It features that the entire file does not need to be downloaded before playback, but is played by downloading and playing, it is the technical basis for video conferences, IP phones, and other applications. RTP is a standard protocol and Key Technology for Real-Time Streaming Media transmission. This article describes how to program Real-Time

IntroductionAt present, the realization of real-time voice, video communication and application in IP network has become a mainstream technology and development direction of network application, this paper introduces the standard protocol RTP for real-time voice and video data transmission in IP protocol family (real-time Transport Protocol) and RTCP (RTP Co

The data in the live555 is sent in the end to be sent using the RTP protocol, which describes the RTP package format.RTP PacketRTP is based on the UDP protocol, and the RTP server passes the UDP protocol, typically sending an RTP packet each time. The client reads the data and then plays it by parsing the

RTP Message Format The RTP message consists of two parts: header and payload. The RTP header format is shown in the following illustration, where: L The version number of the V:RTP protocol, which accounts for 2 digits, and the current protocol version number is 2. L P: Fill mark, 1 digits, if p=1, then fill one or more additional eight-bit groups at the en

(1) Introduction to concepts RTP (Real-Time Transport Protocol) is defined as a transmission protocol for transmitting real-time data, such as audio, video, and analog data, compared with the traditional high-reliability data transmission transport layer protocol, it focuses more on real-time data transmission, services provided by this Protocol include data sequence numbers, time tags, and transmission control.
