Ii. Streaming Media ProtocolReal-Time Transport Protocol (PRT) is a network protocol used to process multimedia data streams over the Internet. It can be used in one-to-one (unicast, unicast) scenarios) or you can transmit streaming media data in real time in a one-to-multiple (Multi-play) network environment. RTP usually uses UDP for multimedia data transmission, but other protocols such as TCP or ATM can be used if needed. The entire RTP protocol consists
delivery technologies mainly fall into two categories: connection-oriented streaming media technologies represented by RTSP/RTP (Real Time Streaming Protocol/Real Time Transfer Protocol, another type is the connectionless HTTP progressive download of mainstream video websites.

These parameters may include the directory information, the encoding type of A/V data, or the server address related to A/V retrieval.
The A/V Helper Program and A/V server run the real-time stream protocol (RTSP, Real-Time Streaming Protocol) to exchange the contr

RTSP (Real Time Streaming Protocol) Real-time stream protocol. RTSP uses the push server method to send a request to the audio and video browser, the Network Camera only keeps pushing audio and video encoded data encapsulated into RTP groups to the browser end.

From the functional level, the player main module can be divided into four layers: RTSP session control layer, RTP data transmission layer, decoding layer, and display playback layer (1 ). The communication between the player and the server is mainly implemented by the RTSP protocol at the application layer and the RTP protocol (Rea
acquisition layer includes obtaining local files, streaming media files, and sending the camera control information. The former only needs to read local files, and obtaining streaming media files requires obtaining media data from the Streaming Media Server. The streaming media file acquisition part includes the session negotiation part, data transmission part, and data buffer part. In the media information negotiation section, you need to use the RTSP

Media Server is a pure RTSP server. Supports multiple media files:
* TS Stream file, with the extension ts.* PS stream file, with the extension mpg.* MPEG-4 video basic stream file with the extension m4e.* MP3 file, with the extension of MP3.* WAV file (PCM) with the extension WAV.* AMR audio file, with the extension. Amr.* AAC file, in ADTs format, with the extension AAC.

Recently, some of the RTSP server projects for PC and embedded platforms have been made, most of which are simple but fully functional and have a strong performance. After comprehensive consideration, the basic is on the basis of live555 based on the development, in the optimization of the Live555 itself and the program internal video data transm

Generally, the stream transmission process includes three steps:
(1) After a user selects a first-class media service, the Web browser and the Web server use HTTP/TCP to exchange control information and obtain the real-time data to be transmitted. Then, the Web browser on the client starts the/V Helper Program and uses HTTP to retrieve relevant parameters from the Web server to initialize the Helper Program. These parameters may include the directory in

Theoretically these three kinds can be used for video broadcast or on-demand. But usually, live broadcast with RTMP, RTSP. And on-demand with HTTP.The following are the characteristics of the following three respectively. The 1,RTMP Protocol (1) is a streaming media pr
