In this article different mathematical models are implemented (using linear regression) in order to estimate or predict the losses that can be produced when delivering television and video content on demand on an IPTV-IMS platform using the RTSP protocols.Several scenarios are evaluated for this.Initially, television is broadcast using the RTSP protocol, switching between wireless and wired networks, and varying the network load.Later this process is repeated when video is transmitted on demand repeating the load conditions and type of network.Each of the proposed scenarios starts with a user receiving the transmission and ends when 10 users are connected.The results of these tests are tabulated, plotted and compared in order to determine how successful the estimation models developed are.
