Anomaly Detection in a Digital Video Broadcasting System Using Timed Automata [PDF]
arXiv, 2017 This paper focuses on detecting anomalies in a digital video broadcasting (DVB) system from providers' perspective. We learn a probabilistic deterministic real timed automaton profiling benign behavior of encryption control in the DVB control access system. This profile is used as a one-class classifier.

Continuous Phase Modulation for Digital Video Broadcasting
International Journal of Computer Applications, 2013 ABSTRACT In this paper, we study the performance of the Digital Video Broadcasting- Terrestrial (DVB-T) system with Continuous Phase Modulation Orthogonal Frequency Division Multiplexing (CPM-OFDM). The proposed structure combines the advantage of mitigating the Peak-to-Average Power Ratio (PAPR) problem in the Power Amplifier (PA)in addition to ...
