Real-Time Streaming: A Comparative Study Between RTSP and WebRTC

摘要

This work presents a comparative study between two of the most used streaming protocols, RTSP and WebRTC. It describes a system designed to evaluate times at live streaming: establishment time and stream reception time from a single source to a large quantity of receivers with the use of smartphones. Two systems that use the commented protocols have been implemented, specifically, two Android applications that use these protocols in the scope of video surveillance at airports. Both systems are composed of a mobile application and a web service. The design of the systems has been done avoiding differences between these protocols for P2P communication in the same local network. Several simulations have been performed to compare them and the obtained results have been used for a comparative study between streaming establishment and sending package times of each protocol.
