The paper is proposing a study and practical experiments of testing methods in digital television, transmitted in Digital Video Broadcasting standard. The main objective of the research presented in this paper was to establish if the testing tools designed and validated for DVB-S, are useable to evaluate DVB-S2. This is important in educational environments and small enterprises, to find new ap...

Integrated Services Digital Broadcasting for Terrestrial (ISDB-T) One-Seg is a Japanese standard for digital television specifically for mobile reception. It uses Orthogonal Frequency Division Multiplexing (OFDM) that provides robustness against multipath fading. A novel approach called Compressed Sensing (CS) has been implemented for estimating the Channel State Information (CSI). The CS impro...

The reception of a COFDM signal is analyzed here for the case where phase noise has been added to the signal, e.g. by a receiver local oscillator. Two effects are distinguished: common phase error (a rotation of the signal constellation) and inter-carrier interference (similar to additive Gaussian noise). It is shown that the amounts of these effects can be deduced from the spectrum of the phas...

This paper presents a compatibility study between future digital television (DTV) and Long Term Evolution (LTE) in the UHF band using Nigeria as a case study. This is done by carrying out an adjacent interference analysis to evaluate the impact of LTE base station on DVB-T2 reception using SEAMCAT software. Results obtained from simulations suggest that deploying LTE in an adjacent band would r...

Consumer and Business demand for Multi-Media services has led to a proliferation of solutions that provide a wide range of services such as Digital Television, Internet Connectivity and others. Set-Top Boxes (STB), the consumer device employed in Digital Video Broadcasting Networks, are mainly used for digital television reception and also for interactive services such as Internet Access or Hom...

This article refers to a reception research of seven television prevention campaigns, done in South Brazil - Porto Alegre, Rio Grande do Sul, with 38 women, ages 18-51 years old, from low-income class. The sample was divided in two groups: women that don't participate in groups that fight against AIDS/HIV and women that participates in groups that fight against AIDS/HIV. Based in a qualitative ...

Digital terrestrial television services using the DVB-T standard will be launched later this year in the UK, followed by Sweden and perhaps other countries soon afterwards. Reception of these services will make use of domestic set-top boxes and integrated receivers using DVB-T demodulator ICs (integrated circuits). The first of these ICs are now becoming available, and it is important that thei...

The recent emergence of e-readers and e-books has brought the death of the book to the centre of current debates on new media. In this article, we analyse alternative narratives that surround the possibility of the disappearance of print books, dominated by fetishism, fears about the end of humanism, and ideas of techno-fundamentalist progress. We argue that, in order to comprehend such narrati...

Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission, where a single data stream is transmitted over a number of lower rate subcarriers. Orthogonal frequency division multiplexing (OFDM) has been chosen as modulation technique for different application wireless communications. OFDM can provide large data rates with sufficient robustness to radio chann...

The paper deals with the first part of results of the Czech Science Foundation research project that was aimed into the simulation and measurement of the transmission distortions of the digital terrestrial television according to DVB-T/H standards. In this part the modulator performance characteristics and its simulation and laboratory measurements are presented with focus on typical DVB-T/H br...
