On the Provisioning of Mobile Digital Terrestrial TV Services to Vehicles With DVB-T
2012
[EN] Most of the DVB-T (Digital Video Broadcasting -Terrestrial) networks deployments worldwide have been designed for fixed rooftop antennas and high transmission capacity, not providing good coverage level for vehicular mobile reception. This letter analyzes how to combine different technical solutions, so far studied individually, in order to increase the robustness of the transmission for vehicular reception to provide in-band mobile services. In particular, we consider: receive antenna diversity, hierarchical modulation, and Application Layer Forward Error Correction (AL-FEC). Performance evaluation results have been obtained by means of simulations, laboratory tests, and field measure…
Indicadores compuestos como metodología innovadora en Comunicación. Aplicación para la evaluación de los medios públicos europeos
2020
The currently dominant scientific production model in the field of Communication exhibits an excess of standardization towards mainly empirical work that is overwhelming caried out using quantitative techniques based on simple statistical analyses, in many cases limiting the presentation of results to a reading of the available data. This article presents an innovative proposal in this area, designed as a new form of dissemination and scientific presentation, with the objective of constructing three composite indicators that, when applied to European public service media, will enable the assessment of the perception of their social value, independence, and management efficiency. Another aim…
Teledu: Transmedia Learning Ecosystem for People at Risk of Exclusion
2021
The TELEDU tele-education ecosystem, integrated by software and hardware components, allows the use of Web resources through Interactive Digital TV (iDTV) without the need to be continuously connected. It works with any existing digital TV standard and is especially useful for users who do not have broadband, being a very effective solution in places where there is a digital divide. The user must have, at least, a cell phone with 3G connection and any of these three options: Digital Terrestrial TV (DTT), Satellite TV or Cable TV. The conception of TELEDU is based on the premise that the software will offer a friendly interaction. Based on this, an interoperable, open and scalable environmen…
The relationship between body and screen in Studio Azzurro’s performances since the 1980s until today
2018
Studio Azzurro is an Italian group that has been working with different performative languages since the 1980s: video installations, theater, video art, cinema, interactive installations, interactive museums. In all these artistic experiences Studio Azzurro has never worked using the languages handed down by tradition, but has always experimented by mixing them with new technologies. The work they have conducted in theater is particular, because the use of new technologies has transformed the concept of theater and has opened the way for the development of new performative forms such as digital or technological theater. In what follows, we will study the relationship between body and screen…
Climate Change in Literature, Television and Film from Norway
2020
Environmental and climatic change has become a frequent motif in contemporary Norwegian literature, television and film, and Norway has the worldwide first organization of writers committed to climate action (The Norwegian Writers’ Climate Campaign, founded in 2013). In this article, we argue that Norwegian climate change fiction and related works draw on elements that relate to specific national and/or Nordic cultural, societal and historical features, and that these elements give these works their distinct identity. We focus on four such features: (1) notions of “Nordicity”; (2) an (imagined) intimate connection between Norwegianness and nature, often seen as a typical element of Norwegia…
Análisis de los factores determinantes del uso de mensajes SMS para participar en programas de televisión
2010
[ES] El envío de mensajes cortos a programas, anuncios o concursos de televisión se ha convertido hoy en día en una fuente importante de ingresos tanto para los operadores de telefonía móvil como para las cadenas y productoras televisivas. El objetivo del presente trabajo es analizar cómo contribuye la actitud y la relación individuo-medio en que el telespectador utilice este servicio de mensajería para participar en los programas televisivos. Los resultados ponen de relieve que tanto la compatibilidad del individuo con el servicio como el entretenimiento percibido al participar en este tipo de programas y la actitud hacia el uso son factores determinantes de la utilización del servicio. [E…
La alteridad en el discurso de la ciencia ficción : identidad y desarraigo en Beforeigners (HBO: 2019- )
2021
La representación del miedo hacia el Otro ha sido una de las temáticas más recurrentes en el género de la ciencia ficción. En esta línea, esta investigación articula un análisis de la serie noruega Beforeigners en torno al discurso de la identidad. Desde una perspectiva cualitativa, se ha realizado un análisis textual que ha puesto de manifiesto que en la serie prevalecen los valores comunitarios y solidarios. En la discusión se han contrapuestos los resultados con otras series del género y se ha evidenciado que la serie rompe con las narrativas típicas de la ciencia ficción. Asimismo, se destaca el tono crítico de la serie hacia las políticas de inmigración de la Unión Europea. The portray…
The Crystal Barrel data acquisition system
1992
The main detector components of the Crystal Barrel (CBAR) experiment at the Low Energy Antiproton Ring (LEAR) at CERN are two proportional wire chambers, a jet drift chamber and an electromagnetic calorimeter composed of 1380 CsI(Tl) crystals, with a total of 4380 analog channels. A description is given of the use of distributed VME-based microcomputers to collect data from the various subdetectors and to merge the full event information in a global event builder. At this level the data are transferred to a mu VAX for tape storage and monitoring. >
An evaluation of exposure metrics in an epidemiologic study on radio and television broadcast transmitters and the risk of childhood leukemia.
2009
Electric field strength values calculated by wave propagation modeling were applied as an exposure metric in a case–control study conducted in Germany to investigate a possible association between radio frequency electromagnetic fields (RF-EMF) emitted from television and radio broadcast transmitters and the risk of childhood leukemia. To validate this approach it was examined at 850 measurement sites whether calculated RF-EMF are an improvement to an exposure proxy based on distance from the place of residence to a transmitter. Further, the agreement between measured and calculated RF-EMF was explored. For dichotomization at the 90% quantiles of the exposure distributions it was found that…
