What is RTSP and how does it work?
RTSP, or Real-Time Streaming Protocol, is a protocol used for streaming media over the internet. It allows users to control the streaming of audio and video content, enabling them to play, pause, and record streams. RTSP works by establishing a connection between the client and the server, and then sending commands to the server to control the stream. The client can request the server to start or stop streaming, and the server will respond accordingly. This protocol is widely used in various applications, including video conferencing, online streaming, and surveillance systems.
The working of RTSP involves a series of steps, including connection setup, stream control, and teardown. When a client requests a stream, it sends a request to the server, which then responds with the stream’s parameters. The client can then send commands to the server to control the stream, such as play, pause, or record. The server will respond to these commands and adjust the stream accordingly. RTSP also supports authentication and authorization, ensuring that only authorized users can access and control the streams. This makes RTSP a secure and reliable protocol for streaming media over the internet.
