The Real-Time Streaming Protocol (RTSP) is a fundamental technology for multimedia streaming, enabling control over audio and video data transmission across IP networks. It uses commands like SETUP, PLAY, PAUSE, and TEARDOWN to manage streaming sessions. While newer protocols like WebRTC and HLS offer different features, RTSP remains essential in applications requiring direct interaction with the media stream, such as surveillance systems and live broadcasting. As technology advances, RTSP may adapt to new standards and formats, ensuring its continued relevance in digital media.
