Dual Screen

Emerging online communication landscapes are reshaping the media panorama through the introduction of models based on hyper-personalization and gamification. Live-streaming phenomena, with platforms like Twitch at the forefront, integrates information, entertainment, and social interaction, asserting its importance as a modern sociocultural phenomenon. This research aims to investigate the current scope of international scientific studies on Twitch and live-streaming. To achieve this, the study employed a systematic literature review according to the PRISMA 2020 protocol, consulting the Scopus and WOS databases from 2008 to 2023, with a total sample of 73 articles. Findings reveal a marked increase in scientific publications from 2019 onwards, indicating a rising interest in this phenomenon. The research predominantly focuses on the critical role of social interaction, its impacts-both positive and negative-the streamer's influence, and the platform's role. The study concludes by pointing out several areas that future research should further explore to fully understand the evolving communicative model and its wider implications beyond the gaming.

Eje de trabajo: Comunicación e investigación. Título: Televisión Digital Interactiva. Nuevos usos de un viejo medio. Palabras claves: Televisión Digital Abierta (TDA); usos de tecnologías; interactividad; apropiación tecnológica. Las consideraciones que se exponen en este artículo forman parte de los primeros resultados que ha arrojado un acercamiento exploratorio a los distintos aspectos que configuran los usos de la Televisión Digital Abierta (TDA) en la región 9na de la Provincia de Buenos Aires 1 . Dejando de lado la vieja señal analógica, que es la que actualmente se continúa consumiendo en la mayoría de los hogares, la Televisión Digital "consiste en el muestreo y codificación de las imágenes en un flujo de datos binarios (ceros y unos) que es transmitido a través de una red de transporte (terrestre, cable, satélite, etc.) hacia un aparato receptor que decodifica y reconstruye la imagen original" 2 . De esta forma, los errores más habituales que presenta la televisión analógica ("lluvia", "fritura", "fantasmas") se verán corregidos en su totalidad, ya que si la transmisión no es óptima, la imagen no se reproducirá; al mismo tiempo, se generará una calidad de imagen y de sonido superior a la recibida por la televisión convencional. En Argentina, la Televisión Digital comenzó el 8 de agosto de 2009, de la mano del Decreto Nº 1148/2009 que dio origen al Sistema Argentino de Televisión Digital Terrestre (SATVD-T) a partir del cual comenzó a implementarse la digitalización de las señales analógicas de televisión. En nuestro país existen aproximadamente 12 millones de televisores, de los cuales un 20% no tiene acceso a la TV paga o por cable 3 , pero si pueden acceder a la Televisión Digital Abierta (TDA) teniendo como mínimo requisito la colocación de un decodificador en el televisor que permita la conversión a las señales digitales y una antena para que las capte. Si bien el acceso a computadoras, celulares y otras tecnologías de la información y la comunicación han desplazado el consumo de televisión, esto no quiere decir que hayan suprimido su existencia, sino que han reconfigurado los hábitos de consumo por parte de los usuarios. La TDA buscará dar acceso a este medio a los sectores más vulnerables a lo largo y ancho del país, de manera gratuita y ofreciendo un servicio de alta calidad, con una amplia oferta de canales, en oposición a la antigua grilla de 4 o 5 canales abiertos (o de aire). Actualmente, según el sitio web oficial de la TDA al momento de finalización de este trabajo se han entregado por parte del Gobierno Nacional, a través del Ministerio de Planificación Federal, Inversiones Públicas y Servicios, 1.080.000 decodificadores distribuidos por todo el país, de los cuales más de 1600 4 han arribado a la región 9na de

In this paper we describe how Twitter is used in various languages. We observe notable differences between languages regarding the use of hashtags, links, mentions, and conversations. We propose two dimensions that can be used to classify languages, each of which is likely to require different ways of analysis.

This article seeks to explain political persuasion in relation to second screening-people's use of a second screen (i.e., smartphone/laptop) while watching television to access further information or discuss TV programs. Employing a two-wave-panel survey in the United States, results show this emergent practice makes people more open to changing their political opinions, particularly among those who habitually use social media for news or frequently interact with others in social media contexts. Participatory online media afford people greater ability to engage in emergent communicative practices that increasingly help to shape public narratives about political events. Some have argued that this newfound ability gives news audiences more power relative to elite social institutions than they had in the past (Benkler, 2006). That is, individuals have become less dependent on political parties, interest groups, and news media organizations as sources of political information, because they are free to rely on information from other citizens. In this vein, some scholars point toward "second screening" as a communication practice that alters the relationship between news media organizations and their audiences (Anstead & O'Loughlin, 2011; Chadwick, Dennis, & Smith, 2016). More than two-thirds of U.S. adults own a smartphone (68%), and nearly half (45%) own a tablet computer (Pew, 2015). These devices are often used while

Commonly conducted alongside political TV viewing, second screening is a new media use behavior that merits explorations at diverse levels. But the research on second screening is still in its infancy. To deeply understand the complicated mechanism of second screening and its influence in a political milieu, this study focuses on the second screening activities aroused by televised political campaign news and programs, and (1) identifies specific categories of second screening activities during television campaign exposure, and (2) establishes the indirect influences of each type of second screening activity on individuals' cognition (political knowledge) and behavior (political participation) through internal (internal political efficacy) and external (political discussion) factors.

This paper focuses on 'political social TV'. Social TV corresponds to two phenomena: TV viewers have the opportunity to react to a program by posting tweets, SMS or Facebook messages, and these digital messages are integrated into the TV program. Thus, social TV is intended to allow users to contribute to public discussions and to facilitate the constitution of a transmedia and digital agora. This paper proposes an analysis of the tweets produced by TV viewers, selected by the program director and displayed on screen during the French political TV program Des Paroles et Des Actes, broadcast by France 2 on 6 February 2014. Through the interactional and pragmatic analysis of these messages, several questions will be addressed: what are the addressee and the reception format of these tweets? Who are the authors of these messages? What are the main functions of these tweets? From a more general perspective, this analysis raises questions about the participatory and dialogical dimensions of social TV and the digital agora.

This article analyses how in the main political talk show on television in Spain, La Sexta Noche, the main themes of the European agenda were silenced or conditioned by the themes of the national, regional and local agenda during the last European elections. The media debate was oriented towards an analysis of the results of national elections and the campaign for regional and local elections that allowed for a greater spectacle, thanks to the shock effect of such polarized ideologies and the trivialization of national politics. This research has studied all the shows of the programme broadcast as of the national elections on 28th April 2019 up until the European elections held on 26th May 2019, analysing the main topics covered and the kind and tone of discourses made. Due to the fact that controversial political issues are preferred to more relevant ones in order to generate a spectacle and bigger audiences, the results indicate that the political talk show analysed contributes to the trivialization of debates and the impoverishment of public space, aided by formal elements inherent in the infotainment genre.

The use of second screening to express emotions and opinions while watching television has proliferated among media consumers. However, the relationships proposed so far between second screening and political outcomes are relatively limited in scope and simple. This study contributes to the literature in two ways. 1) We identify how second screening influences users' online participation through two mediators-elaboration on social media and social media political efficacy. As such, this study provides empirical evidence of second screening's political effects by uncovering specific indirect mechanism. 2) Using a sample of second screeners in China, this study fills in a blank of the current Western-dominant second screening research.

Online social media such as Twitter, Facebook, Wikis and Linkedin have made a great impact on the way we consume information in our day to day life. Now it has become increasingly important that we come across appropriate content from the social media to avoid information explosion. In case of Twitter, popular information can be tracked using hashtags. Studying the characteristics of tweets containing hashtags becomes important for a number of tasks, such as breaking news detection, personalized message recommendation, friends recommendation, and sentiment analysis among others. In this paper, we have analyzed Twitter data based on trending hashtags, which is widely used nowadays. We have used event based hashtags to know users' thoughts on those events and to decide whether the rest of the users might find it interesting or not. We have used topic modeling, which reveals the hidden thematic structure of the documents (tweets in this case) in addition to sentiment analysis in exploring and summarizing the content of the documents. A technique to find the interestingness of event based twitter hashtag and the associated sentiment has been proposed. The proposed technique helps twitter follower to read, relevant and interesting hashtag.

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 Media — 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 one hand, it was a chance to usenew audiovisual methods to better convey political information to citizens. On the other hand, it gave the network and its masters the chance to renounce the shameless political partisanship that had so marred Canal 9’s history. This paper looks at the extent to whi...

A field experiment was conducted to analyze the third and final 2016 presidential debate. Randomly assigned participants watched the debate in the format of mainly solo camera shots that alternate between the candidates (i.e., switched feed), or with both candidates framed side-by-side on screen (i.e., split screen feed). Though viewer feelings of positivity toward the candidates did not differ, visual presentation style had a significant effect on trait judgments for Donald Trump overall. Participants watching Trump on the switched camera feed perceived him as significantly more Sophisticated, Honest, Attractive, Sincere, Strong, Active, Intelligent, Trustworthy, and Generous. There was not an effect for Hillary Clinton’s trait ratings overall, though she was perceived as significantly more Strong, Competent, and Intelligent by those watching the switched feed. This suggests that visual presentation style significantly influenced viewer perceptions. Political ideology was a signifi...

In many societies alcohol is a legal and common recreational substance and socially accepted. Alcohol consumption often comes along with social events as it helps people to increase their sociability and to overcome their inhibitions. On the other hand we know that increased alcohol consumption can lead to serious health issues, such as cancer, cardiovascular diseases and diseases of the digestive system, to mention a few. This work examines alcohol consumption during the FIFA Football World Cup 2018, particularly the usage of alcohol related information on Twitter. For this we analyse the tweeting behaviour and show that the tournament strongly increases the interest in beer. Furthermore we show that countries who had to leave the tournament at early stage might have done something good to their fans as the interest in beer decreased again.

Using survey data on second screening activities while watching eight types of television programs among 570 Twitter users, we identified four types of second screeners: Specifically, Second Screeners for Politics and News mainly second screens for political events and news; Second Screeners for Sporting Events and Commercials mostly second screens for sporting events and commercials; High Second Screeners second screens all eight types of television programming, with particularly high levels while watching scripted dramas, situation comedies, and live television programming; Low Second Screeners do not exhibit salient second screening behaviors. Matching survey data with a year’s worth of Twitter activities from survey respondents, this paper extends the previous research on second screening as purposive hybrid media practice by examining how fine-grained Twitter behaviors are associated with four types second screeners. We discuss the implications of how different types of televis...

Real-time response methods, which were developed by media and communication researchers as early as the 1940s, have significant potential for understanding media audiences today. However, this potential is not realized fully by current methods such as “the worm,” which are limited to collecting positive and negative responses and fail to examine why audience members respond as they do. This article advocates a new research agenda for understanding how audiences respond to political messages through real-time response methods. Instead of measuring preferences, we suggest that real-time response methods should focus on people’s sense of whether their democratic capabilities are advanced—an approach that would provide a more critical as well as a more nuanced understanding of how audiences respond to political communication. We describe an innovative Web-based app our team has designed to capture audience responses to political messages, and we outline some key questions we hope to add...

Dentro del nuevo modelo comunicativo caracterizado por la convergencia multimedia, las aplicaciones de segunda pantalla televisiva para dispositivos móviles están conociendo un lento crecimiento en España. La de mayor implantación y alcance actualmente es Ant 3.0, de ahí su interés como objeto de análisis. Por ello este artículo propone conocer el funcionamiento y principales servicios que ofrece la primera aplicación de contenido sincrónica en España desde la praxis, previo acercamiento al concepto de actividad de segunda pantalla.

Second screening is a relatively new set of media practices that arguably empower audiences to shape public narratives alongside news organizations and political elites. But in developing countries such as Colombia, it is important to examine who participates in this process, as substantial inequalities in both access to and use of information and communication technologies (ICTs) persist. This study examines how socioeconomic status (SES) relates to the adoption of second screening practices in Colombia, a country in which the technological access and literacy necessary to engage in these practices are becoming widespread but are not yet ubiquitous. Based on a random sample of face-to-face interviews, results show evidence of persistent digital divides in Colombia in terms of ICT access, ICT use, and second screening for news. Additionally, results indicate that the relationship between SES and second screening for news is indirect, mediated through technological access and public ...

Los cambios sociológicos, culturales y simbólicos que se han producido en la era digital han tenido una gran repercusión en el ámbito de la comunicación y evidencian que es necesario que las marcas tracen nuevos caminos en su búsqueda para conectar con sus públicos. Ante esta realidad, nuestra propuesta de rock&love apuesta por un modo diferente de aproximarse a los públicos, más en sintonía con las nuevas posibilidades que brinda el contexto digital. Este artículo presenta una investigación en la que se parte de la hipótesis de que la comunicación para móviles —vehiculada a través de apps principalmente— es el terreno idóneo para que las marcas se comporten de acuerdo a los postulados del rock&love y tiene como principal objetivo la identificación de los factores que permiten determinar cuáles son los recursos creativos que responden a los conceptos de rock y love. Para ello, se ha realizado un análisis de contenido a un corpus de trabajo compuesto por las campañas ganadoras del Fe...

 Internet se ha convertido en el medio de referencia entre los jóvenes y su uso está muy extendido se pueden identificar perfiles de usuarios respecto a la actitud hacia el medio interactivo y su estilo de navegación. El objetivo del estudio se centra en identificar dicho perfiles y poner a prueba su relación con su comportamiento en Internet. El estudio utiliza una metodología correlacional, con una muestra de conveniencia formada por 320 jóvenes entre 14 y 19 años procedentes de varios centros de educación secundaria. Los resultados muestran que se pueden identificar varios patrones de los adolescentes en el consumo de medios interactivos en función de su estilo de navegación y actitud hacia el medio. El estilo de navegación exploratorio está asociado a participar en actividades comerciales de la red y a dedicar más tiempo al medio interactivo particularmente durante la semana. Así mismo, los jóvenes que se enfrentan al medio con una actitud más confiada y ven el medio como un veh...

Spatial analysis and social network analysis typically take into consideration social processes in specific contexts of geographical or network space. The research in political science increasingly strives to model heterogeneity and spatial dependence. To better understand and geographically model the relationship between "nonpolitical" events, streaming data from social networks, and political climate was the primary objective of the current study. Geographic information systems (GIS) are useful tools in the organization and analysis of streaming data from social networks. In this study, geographical and statistical analysis were combined in order to define the temporal and spatial nature of the data eminating from the popular social network Twitter during the 2014 FIFA World Cup. The study spans the entire globe because Twitter's geotagging function, the fundamental data that makes this study possible, is not limited to a geographic area. By examining the public reactions to an inherenlty non-political event, this study serves to illuminate broader questions about social behavior and spatial dependence. From a practical perspective, the analyses demonstrate how the discussion of political topics fluсtuate according to football matches. Tableau and Rapidminer, in addition to a set basic statistical methods, were applied to find patterns in the social behavior in space and time in different geographic regions. It was found some insight into the relationship between an ostensibly non-political event-the World Cup-and public opinion transmitted by social media. The methodology could serve as a prototype for future studies and guide policy makers in governmental and non-governmental organizations in gauging the public opinion in certain geographic locations.

The distributed nature of cloud computing makes it vulnerable and prone to sophisticated distributed intrusion attacks such as Distributed Denial of Service (DDoS) attacks. In order to detect those network attacks and respond swiftly, there must be a reliable defense system designed to distinguish anomalies embedded in legitimate traffic. In order to ensure the high availability of any offered services, the data center resources must be protected from DDoS threats. The existing solutions for monitoring incoming traffic and detecting DDoS attacks have excessive false alarms and become ineffective in early detection of high level flooding attacks and resolution of the cloud service availability issues. Therefore, it is necessary to devise a model that can detect DDoS attacks and serve the legitimate users with available resources with minimal downtime. This research paper addresses this need by investigating the multivariate correlation among the selected and ranked features. This stu...

Digital media has gradually replaced paper as a medium of communication. These new media have need the existence of mechanical devices for reading documents that until now were directly manipulated by the reader. In printed paper graphical layout of text and images depended on each book. The choice of size, color and proportion was a consequence of the structure of the work. However, in digital age, graphic layout depends on the device that makes available documents to the reader. Despite its obvious advantages to reorder the information, have incorporated interactive procedures from print media that were relevant to the reader’s ability to see, read and understand the whole layout. This paper analyzes the survival of graphical interaction models in these new media.

Podemos entender un "mensaje híbrido" como todo intento pagado de influenciar a las audiencias para un objetivo comercial, utilizando comunicaciones que proyectan un carácter no-comercial (Balasubramanian, 1994). Durante las dos décadas transcurridas, los mensajes híbridos han crecido en importancia y presencia. Algunos de estos mensajes, como el patrocinio o el emplazamiento de producto, han sido ampliamente estudiados, no así formas más novedosas como el branded content, el content marketing o el branded entertainment. No existe consenso entre los diferentes autores sobre el alcance, naturaleza, definición y clasificación de estas nuevas formas de comunicación. En este trabajo se ha realizado una exhaustiva revisión de las publicaciones aparecidas en los últimos años, lo que ha permitido clarificar los tres conceptos aludidos, así como realizar una propuesta de clasificación de los mensajes híbridos, en la que el principal factor de diferenciación es la intencionalidad en la creación del contenido.

Currently, social networks present information of great relevance to various government agencies and different types of companies, which need knowledge insights for their business strategies. From this point of view, an important technique for data analysis is to create and maintain an environment for collecting data and transforming them into intelligence information to enable analysts to observe the evolution of a given topic, elaborate the analysis hypothesis, identify botnets, and generate data to aid in the decision-making process. Focusing on collecting, analyzing, and supporting decision-making, this paper proposes an architecture designed to monitor and perform anonymous real-time searches in tweets to generate information allowing sentiment analysis on a given subject. Therefore, a technological structure and its implementation are defined, followed by processes for data collection and analysis. The results obtained indicate that the proposed solution provides a high capaci...

Political communication in social media has gained increasing importance in the last years. In this study, we analyze the political parties’ communication on Twitter and understand the sentiment of their communication. First by identifying their communication performance regarding the daily number of tweets, favorite tweets, number of retweets per day and per political party. We present a sentiment analysis by the political party using tweets data. In this study, we propose an explanatory model with the main drivers of retweets. To conduct this study, our approach used data analysis and machine learning techniques methods. Results indicate the main determinants that influence future retweets of political posts globally. Here we present a comparison of the communication content between tweets posts and the political parties’ programs available on their institutional websites. We identify the similarities between tweets and formal programs per party and among all parties. This study c...

Event detection over microblogs has attracted great research interest due to its wide application in crisis management and decision making etc. In natural disasters, complex events are reported in real time on social media sites, but these reports are invisible to crisis coordinators. Detecting these crisis events helps watchers to make right decisions rapidly, reducing injuries, deaths and economic loss. In sporting activities, detecting events helps audiences make better and more timely game viewing plans. However, existing event detection techniques are not effective at handling complex social events that evolve over time. In this

La revolución tecnológica ha facilitado que la distribución de contenidos audiovisuales se realice más allá de los soportes tradicionales como el televisor y se extienda a los dispositivos móviles (teléfonos, tabletas, etc.). Las cadenas de televisión distribuyen los contenidos en todas las plataformas posibles y ven en los dispositivos móviles, una vía para el consumo multiplataforma de sus contenidos. El espectador pasa a ser un usuario que puede generar contenido o multiplicar la incidencia del mismo. Esta investigación se centra en el análisis de los contenidos que distribuyen en tabletas, los operadores de televisión generalista en España (TVE, Mediaset y Atresmedia) así como el estudio de la interactividad que mantienen en estos dispositivos. Para realizar el análisis se ha utilizado una plantilla original diseñada por los autores para identificar cada uno de los elementos que interfieren en la interactividad de las aplicaciones investigadas y, también, se ha elaborado un anál...

Sacar la televisión de la televisión representa darle al usuario el control total de los contenidos audiovisuales. Tras el prolongado éxito de las series de televisión la presente investigación profundiza en el modelo de negocio y comunicación desarrollado por los grandes conglomerados multimediáticos para la generación de nuevos fenómenos de masas. El texto explora las megatendencias de la industria del entretenimiento, la evolución de la televisión, los cambios en las audiencias y sus motivaciones para describir el tipo de conexiones que establecen los jóvenes espectadores con los contenidos televisivos. Se particulariza el análisis tomando como referencia la teleserie Lost para la construcción teórica del concepto de Hipertelevisión; un nuevo modelo de producción audiovisual que contempla contenidos multimediáticos interactivos, hipertextuales, personalizdos, con servicios integrados y transmitidos por múltiples canales. Asimismo la investigación presenta las estrategias desarrolladas para garantizar un modelo de negocio efectivo para la industria televisiva ofreciendo estrategias integrales para replicar dichos éxitos en otros contenidos. La nueva experiencia televisiva comprende el desarrollo de estrategias de integración tecnológica, publicitaria, de contenido, mercadológicas y corporativas. La investigación ofrece un análisis de caso contemplando las estrategias emprendidas por corporativos como Walt Disney Corp así como las iniciativas desarrolladas por los principales actores de los hiperconglomerados mediáticos para impulsar sus contenidos fuera de los medios tradicionales en un entorno global.

A partir del libro Contro il colonialismo digitale de Roberto Casati, se analizan las nuevas formas de lectura de textos digitales para establecer sus especificidades, principalmente en lo que concierne a posibles cambios cognitivos, con el objetivo de estudiar cuál puede ser el medio idóneo destinado a la enseñanza. Este análisis tendrá una primera aproximación ontológica al texto digital para reflexionar posteriormente sobre las prácticas que se están implantando en nuestra sociedad. http://www.icono14.net/ojs/index.php/icono14/article/view/660 Icono 14, 2014

Gracias a la digitalización, los contenidos televisivos pueden disfrutarse en múltiples pantallas además del televisor. Las compañías de televisión han desarrollado un modelo de televisión online e interactivo que permite un consumo personalizado a través de varios soportes. Siguiendo el modelo de las televisiones nacionales en el entorno digital, analizamos aquí la oferta digital de las televisiones públicas autonómicas en España desde la óptica de la medición de audiencias. La segunda fuente de financiación de estas televisiones proviene de la publicidad y los anunciantes demandan datos de audiencia para invertir en los medios. Por eso, encontrar un sistema de medición de audiencias que unifique todos los dispositivos es esencial para el desarrollo de la estrategia online desde el punto de vista comercial. Para el análisis se han elegido las televisiones autonómicas pioneras, la Corporació Catalana de Mitjans Audiovisuals (CCMA) y Euskal Irrati Telebista (EITB). La metodología empleada será la observación directa y análisis crítico.

Advanced analysis techniques and big data approaches have abundantly been used on Twitter data for sentiment analysis. We expand on this knowledge by analyzing the relation between the native language used in tweets and emotional state. Through MapReduce we have analyzed a sample of 16 million tweets made during the 2014 FIFA World Cup. Our research attempts to show that emotions may be an influence on the use of language on Twitter. Sufficient correlation has been found between the language used to tweet and events that took place during matches.
