Abstract

The paper presents a new mathematical model of a link carrying by the Real Time Transport Protocol. The model attempts to meet the key features of the real link functioning like the frame delays, losses, bursting reception etc. The proposed approach is based on the Hidden Markov concept. The unobservable state is assumed to be a finite-dimensional Markov process. The observation is a non-Markovian multivariate point process that indicates heterogenous frames reception. The paper also contains the formulation and solution to the filtering problem of the hidden link state given the observable multivariate point process. Proposed link model validity and filtering algorithm performance are illustrated by processing of captured real video streams delivered via 3G mobile network.
