Automatic Genre and Show Identification of Broadcast Media [PDF]
arXiv, 2016 Huge amounts of digital videos are being produced and broadcast every day, leading to giant media archives. Effective techniques are needed to make such data accessible further. Automatic meta-data labelling of broadcast media is an essential task for multimedia indexing, where it is standard to use multi-modal input for such purposes.

A novel channel estimation based on spread pilots for terrestrial digital video broadcasting [PDF]
Broadband Multimedia Systems and Broadcasting, Las Vegas :
\'Etats-Unis d'Am\'erique (2008), 2008 In this paper, we propose a novel channel estimation technique based on spread pilots for digital video broadcasting. This technique consists in adding a linear preceding function before the OFDM modulation and dedicating one of the preceding sequence to transmit the pilot symbols for the channel estimation.

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.
