Broadcasting Indigenous Voices
2008
Ethnic minority media embody much of the multiculturalist, multilingual and transnational changes in the media landscape and in the wider societal frame as well. Often minority media aim at providing relevant information, but also alternative publicity and empowering experiences in regard to their own identity, language and culture. Through an analysis of journalists' interviews and ethnographic data, this article examines how these tendencies, possibilities and limitations are played out in the indigenous Sami media. The findings suggest that the Sami journalists have managed to provide an alternative public space and contribute to linguistic revitalization. Yet, working within translocal …
Audiovisual Representation in Spanish and European Election Debates
2020
The presence of ever more conflicting stances between Europhiles and Eurosceptics has revealed some audiovisual discourses unknown until now. The fragmentation of inconclusive narrative discourse and staged situations with a clear intent to clash all make it necessary to analyse in detail the role given by the audiovisual media to the European process of democratisation. This study addresses the audiovisual discourse in Spanish public television (TVE) with the intention of discovering how the different topics addressed in debates are dealt with in audiovisual production, and whether those topics have benefited from certain decisions by the production team that are subjective a priori. Using…
An efficient distributed algorithm for generating and updating multicast trees
2006
As group applications are becoming widespread, efficient network utilization becomes a growing concern. Multicast transmission represents a necessary lower network service for the wide diffusion of new multimedia network applications. Multicast transmission may use network resources more efficiently than multiple point-to-point messages; however, creating optimal multicast trees (Steiner Tree Problem in networks) is prohibitively expensive. This paper proposes a distributed algorithm for the heuristic solution of the Steiner Tree Problem, allowing the construction of effective distribution trees using a coordination protocol among the network nodes. Furthermore, we propose a novel distribut…
Filecasting for streaming content delivery in IP datacast over DVB-H systems
2008
In this paper we investigate the potential gain that can be obtained in DVB-H by delivering streaming content as a succession of time-constrained flies using Application Layer - Forward Error Correction (AL-FEC) for improving the reception for mobile terminals. Compared to the conventional approach with link layer MPE-FEC, this technique allows to increase the robustness of the DVB-H transmission not only as a function of the capacity devoted for error repair (FEC overhead), but also as a function of the number of data bursts coded jointly ("file" or, source data block, size). The main drawback of this approach is an increase of the network latency proportional to the source block size, tha…
Streaming: ventajas, desafíos y oportunidades de las radiotelevisiones para captar audiencias
2021
La investigación muestra el crecimiento del consumo de streaming en los últimos años y refleja su incremento exponencial a raíz de la pandemia por la Covid 19 en 2020. La base científica cita a los autores más relevantes en esta temática y está avalada por los estudios e informes de organismos oficiales y privados de relevancia internacional. Se estudia el origen del streaming, su evolución y futuro con la ayuda de las nuevas herramientas tecnológicas, como las appsque permiten a los periodistas y al público poder entrar en directo en un informativo. Ello suponenuevas oportunidades de negocio para las radiotelevisiones generalistas creadoras de contenido en España. La investigación muestra …
“Not Only for a Celebration of Competitive Overwatch but Also for National Pride”: Sportificating the Overwatch World Cup 2016
2020
While the most popular forms of organized competitive digital gaming, also known as eSports, have begun finding their place within and in relation to both mainstream entertainment culture and the field of traditional sports, their history is one of struggling to be accepted as “true sports.” Partly because of this history, great effort has been put into the sportification of eSports by presenting competitions in familiar ways adapted from traditional sports. In this article, we examine the process of sportification of eSports in the context of tournament broadcasts. We analyze the Overwatch World Cup 2016 tournament, comparing its final broadcast to the 2014 FIFA World Cup’s final broadcast…
Valencian Politicians under the spotlight of the À Punt TV network: A study of television coverage of the 2019 regional elections
2020
Despite repeated failures by the former Valencian television network — Canal 9 [Channel 9] — to live up to its public broadcasting duties, the station’s closure in 2013 still came as a shock. The step by the regional government (then run by the Conservative Partido Popular — PP) had a huge public impact, depriving Valencians of their public TV network at a stroke. That is why Valencian society had high hopes when a new public media platform — Punt Mèdia — was launched. Among other things, politicians and broadcasters needed to show that a more even-handed, professional approach could be taken to media reporting. The 2019 Regional Elections were a wonderful opportunity to prove this. On the …
Nonverbal Influence During Televised Debates
2016
Experimental studies find a strong influence of nonverbal signals on the evaluation of political candidates when raters are asked to judge unknown candidates from short-duration exposures. Yet when viewers are exposed to candidates’ verbal and nonverbal communication in a more naturally occurring context, the presence of verbal communication can make the influence of nonverbal communication seem attenuated. To link these findings, the present study uses continuous response measurement to uncover the relative influence of verbal and nonverbal communication on political opinion formation during a debate clip lasting about 9 minutes. The analysis suggests that nonverbal communication influenc…
ADM : A Density And Priority Levels Aware Protocol For Broadcasting In Vehicular Ad-Hoc Networks
2014
The broadcasting communication mode is widely used in Vehicular Ad~hoc Networks (VANETs). It is used for sending emergency messages, road-traffic information or to help routing protocols to determine routes. This communication mode is known to be hard to achieve efficiently since it depends on the network density. Indeed, broadcasting methods may cause network congestion if they are not well designed. This paper introduces a novel Autonomic Dissemination Method (ADM) which delivers messages in accordance with given message classes and network density levels. The proposed approach is based on two steps: an offline optimization process and an online adaptation to the network characteristics. …
Audiovisual constructs of Paralympic Games : scalarity and camera angle
2014
This research will analyze the variables differentiating between the audiovisual television of the XIII edition of the Paralympic Games and the Games of the XXIX Olympiad, held in Beijing from the 7th of September to the 17th, 2008. This study will serve as a methodological basis for similar future research. By means of a qualitative and quantitative methodology, this study also focuses on determining if TV representations of Paralympic sportspersons favour their social integration or if, on the contrary, lead to higher stigmatization.
