The RTSP is a level protocol application for control over the delivery of real-time data such as audio and video; it establishes and controls one or more time-synchronised broadcasts of continuous media (Schulzrinne et al., 1998). Through RTSP, the algorithm identifies each camera with the information provided by the NVR, using their IP as an identifier, to know the exact location of each one, selects the channel to analyse, and the video is transmitted to the website where, from the backend, it is first transformed into photo frames. After that, they are consumed by the model that is in charge, the frames are analysed in search of a detected face and, if so, the comparison is made in the knowledge base; if a similarity is found, the queries are executed to extract the personal information of the identified individual, thus activating the actions of the notification module.
Audio formats and data interchange

Various real-time protocols have also been developed for use on the Internet, such as RTP (real-time transport protocol). Here packets are time-stamped and may be reassembled in the correct order and synchronised with a receiver clock. RTP does not guarantee quality of service or reserve bandwidth but this can be handled by a protocol known as RSVP (reservation protocol). RTSP is the real-time streaming protocol that manages more sophisticated functionality for streaming media servers and players, such a stream control (play, stop, fast-forward, etc.) and multicast (streaming to numerous receivers).
Media Transport Protocol and Media Negotiation
Published in Radhika Ranjan Roy, Handbook on Session Initiation Protocol, 2018
The Real-Time Streaming Protocol (RTSP), an application-level protocol, is being developed for control over the delivery of data with real-time properties of the near-RT media stream. RTSP (RFC 2326) provides an extensible framework to enable controlled, on-demand delivery of real-time data, such as audio and video. Sources of data can include both live data feeds and stored clips. This protocol is intended to control multiple data delivery sessions; provide a means for choosing delivery channels such as UDP, multicast UDP, and TCP; and to provide a means for choosing delivery mechanisms based on RTP (RFC 3550).

Streaming is the process of dividing data in the file is bro-ken into small packets that are sent in a steady and continuous flow, as a stream to the end device. As soon as few initial data packets received, the playback starts as the rest of the packets are transferred to the end user's device while playing. The client plays out buffer makes sure that the playback to continue uninterrupted despite variations in the rate of received rate and network delay. RTP over UDP widely used in low latency media and entertainment applications such as streaming, video telephony, video conference, set top box application and push-to-talk features. RTP and RTCP protocols are used for payload transmission and control, respectively. Generally Real Time Streaming Protocol (RTSP) over TCP is used for session initiation and description even though specification allows RTSP over UDP.
