Real Time Streaming Protocol (RTSP protocol)

RTSP is co-sponsored by the RealNetworks and Netscape, and the one to many application protocol defines how IP networks through the delivery of multimedia data. RTSP is located in the system structure on top of RTP and RTCP, which uses TCP or RTP for data transmission. Compared with the RTSP HTTP, HTTP send HTML, and RTP is the multimedia data transmission. HTTP request sent by the client, the server responds; use RTSP, the client and the server can request that the RTSP can be bidirectional.
Real Time Streaming Protocol (RTSP) is the application-level protocol to control real-time data transmission. RTSP provides an extensible framework to enable real-time data, such as audio and video, controlled, on-demand possible. Data sources include field data and the data stored in the clip. The agreement aims to control the multiple data transmission connections, for the selection of transmission channels, such as UDP, multicast UDP and TCP, provides a means for selection is based on the transmission mechanism of RTP method.
