audio/video media, while TCP is used for data and control signaling transmission. The main difference between UDP and TCP is that the two differ in how to achieve reliable transmission of information. The TCP protocol includes a special delivery guarantee mechanism, and when the data receiver receives the message from the sender, it automatically sends a confirmation message to the sender, and the sender will wait until the confirmation message is re

Real-time transmission protocol RTP (Realtime Transport Protocol) is a transmission protocol for multimedia data streams over the Internet. It is published by IETF (Internet Engineering Task Group) as rfc1889. RTP is defined to work during one-to-one or one-to-many transmission. It aims to provide time information and implement stream synchronization. Typical RTP

recorder Remote Control Protocol ".1.1. Introduction to RTSP To implement the RTSP control function, not only the protocol, but also the media player and Media Server ). The relationship between media servers and media players is the relationship between servers and customers. The biggest difference between a media server and a common web server is that a Media Server supports stream audio and video transmission, therefore, you can download and play

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

-bit length fields that provide the number of 32-bit characters in the extended header except the first 4 bytes (So 0 is valid ). A maximum of one extension header can be appended to the RTP Header. In order to allow multiple interoperability for independent testing of different header extensions, or to allow a specific implementation of additional header extensions, the header 16 bits of the header extension are reserved as differentiated identifiers

RTSP is similar to HTTP in terms of syntax and message parameters. RTSP is used to control the transmission of media stream

stream. (4) The streaming media server uses the RTP/UDP protocol to transmit audio/video data to the client. Once audio/video data arrives at the client, the audio/video client program can play the output. It should be noted that in stream transmission, two different communication protocols, RTP/udp and RTSP/tcp, are used to establish a connection with the Streaming Media Server, this is to redirect the se

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 m

it is the problem with the program you're writing). If you understand above, then we are further: in fact, the timestamp increase is not a microsecond in our usual sense, but it increases the length of time for a sample interval. For instance. Different acquisition has different sampling frequency, for example, the general audio is 8K sampling frequency, that is, 8 times a millisecond collection of data, that is, each sampling interval is 1/8ms, and timestamp an increase of 1 means that a sampl
