Today, with increased internet access, users are often interested in new content-based multimedia applications of high added value such as interactive TV, video on demand (VoD), and catch-up TV services such as YouTube or Dailymotion frameworks. Despite the easy and rapid access to media information of these services, they present the risk of the wide propagation of fake news. As a solution, the authors propose that the input for these services must be from a trustworthy traditional media, precisely TV program content. So, the automatic process of TV program identification and their internal segmentation facilitate the availability of these programs. In this chapter, the major originality of the authors' approach is the use of contextual and operational characteristics of TV production rules as prior knowledge that captures the structure for recurrent TV news program content. The authors validate their approach by experiments conducted using the TRECVID dataset that demonstrate its robustness.

The different uses of large TV streams have continued to diversify since the appearance of digital TV. For conveniently retrieving and navigating in TV streams, users are often interested in new content-based multimedia applications of high added value such as Interactive TV, Video on Demand (VoD), YouTube or Dailymotion. These applications offer fast and easy access to best explore a particular TV program. So, the automatic process of TV program identification and their internal segmentation facilitate the availability of these programs. Therefore, it is necessary at first, to be able to retrieve a particular program within a large TV stream and secondly segment this program into semantic units related to appropriate retrieval entities. In this paper, the major originality of the authors' approach is the use of contextual and operational characteristics of TV production/post-production rules as prior knowledge that captures the structure for recurrent TV news program content. The authors validate their approach by experiments conducted using the TRECVID dataset that demonstrate its robustness.

TV stream is a major source of multimedia data. The proposed method aims to enable a good exploitation of this source of video by multimedia services social community, and video-sharing platforms In this work, we propose an approach to the automatic topics segmentation of news video. The originality of the approach is the use of Clustering of Histogram of Orientation Gradients (HOG) faces as prior knowledge. This knowledge is modeled as images which governs the structuring of TV stream content. This structuring is carried out on two levels. The first consists in the identification of anchorperson by Single-Linkage Clustering of HOG faces. The second level aims to identify the topics of news program due to the large audience because of the pertinent information they contain. Experiments comparing the proposed technique to similar works were carried out on the TREC Video Retrieval Evaluation (TRECVID) 2003 database. The results show significant improvements to TV news structuring exceeding 96 %.

This study investigates how exposure to different news sources, propensity to vote (PTV) for a party and demographics are related to belief in conspiracy theories drawing on three repeated cross-sectional surveys in Germany 2017–2019. Results show that frequent exposure to alternative news sites and video-sharing platforms increased conspiratorial beliefs. Frequency of exposure to the quality press, public service TV news, and news aggregators diminished beliefs in conspiracy theories. Exposure to TV news, legacy media online, tabloids, social media, and user comments was unrelated to such beliefs. PTV for far left and right parties increased conspiratorial beliefs, moderate party preference reduced them.

Tv Culture

As media globalization has progressed, transnational media have evolved, and this article contends that a new generation has emerged. The first that developed in the latter part of the twentieth century consists of cross-border TV networks and formats. The second is the rise of streaming platforms. During the first generation, the transnational remained a professional practice out of viewers’ reach. With the arrival of the second generation, the transnational has become an everyday mode of media consumption and interaction. Online entertainment services have altered the status of the transnational within TV culture, and what was once at the margins now sits at the core. This article theorizes the notion of the transnational before examining the first and second generations of cross-border media. Considering the advent of streaming, it divides the market into three spaces: subscription video on demand (SVoD), advertising video on demand (AVoD) and video sharing. This article demonstrates how transnational consumption makes SVoD platforms more cosmopolitan than cross-border TV networks. Turning to video-sharing platforms – YouTube in particular – it argues that in the history of TV culture this constitutes a shift in status of the transnational by turning a professional practice into a popular one performed by millions. Based on interviews, this article shows how international access lowers the threshold of economic viability for content creators, while users get involved in cross-border conversations through memetic videos and comments. It is no longer place but technology that determines the fate of stories and ideas, and internet delivery has loosened the ties between TV culture and national culture more than ever.

Discursive Approach

AbstractThis article aims to show the added value of studying transnational advocacy networks through a discursive approach in order to better understand the outcomes of norm diffusion in postconflict contexts. I argue that constructivist approaches to norm diffusion fall short as an explanation of norm adoption because they assume an automatic process of norm propagation through socialisation mechanisms. The first goal of the article is then to discuss how the internal dynamics of discourse negotiation in transnational advocacy networks impact the diffusion and implementation of international norms. The second goal is to propose the concept of the rebound effect and to explore the conditions under which it takes place. Through data collected during extended fieldwork, the article examines a prominent case, namely the transnational campaign for the implementation of United Nations Security Council Resolution 1325 on Women, Peace, and Security in Burundi and Liberia. I ask why and how the campaign was understood as a success in Liberia and as a failure in Burundi. I argue that there is another way of looking at these cases in less dichotomised ways. Crucially, my findings demonstrate how in both cases a very particular discourse on gender security is (re)produced through power relations between local and transnational activists limiting the type of policies that are advocated for and depoliticising the grassroots.

The Impact

AbstractA fundamental component of liberal democracy – citizen knowledge – has only recently been examined in Japan; rarer still are assessments of the impact of media consumption on political awareness. In this paper, we utilize two recent sources – the Japanese Election Studies III (JESIII) and GLOPE2005 – to address two related questions: (1) what factors influence Japanese political knowledge? and (2) is the changing media environment in Japan having an influence on what citizens know about political affairs? With regard to the first question, we find, in line with previous studies in the US context, that knowledge is explained by education, gender, and politically impinged employment as base factors, with interest, efficacy, and civic duty playing a role as second-stage behavioral factors. Evidence of other traits presumed to distinguish the more informed Japanese – dissatisfaction with politics and community mobilization context (living in urban areas, districts with higher voter turnout, and having larger social networks – remains mixed. Regarding the second question, we find that the effects of media exposure on knowledge vary. Where the GLOPE2005 finds an influence of regular newspaper reading, the JESIII indicates that watching a TV news program ‘often’ also boosts knowledge. The JESIII results reveal further that,ceteris paribus, regular exposure to NHK contributes to higher levels of knowledge at a rate that is comparable to a one unit increase in educational attainment. Conversely, we find that softer news programs (e.g., Fuji TV'sSuper News) have a depressive effect that appears to decrease knowledge as exposure accumulates. The direction of the causal arrow is not entirely clear. At the same time, our findings lend credence to previous work that raises concerns about the ‘infotainization’ of Japanese (and US) news programming (e.g., Taniguchi, 2007; Prior, 2005). Rather than demystifying or democratizing Japanese politics, softer programs may simply be perpetuating extant gaps between elites and the public.

The present work tried to ponder about the communication strategies employed by a local television station, TV Anhanguera, an affiliate of Rede Globo in the state of Goiás, during the Covid-19 Pandemic period, with regard to the professional exercise of the presenters of Bom Dia Goiás, Anhanguera Newspaper 1st edition and Anhanguera Newspaper 2nd edition. From the monitoring of the three TV news programs for a period of two months, an analysis was made of the mediation built with the viewers in view of the policy of rotation of professionals adopted by the broadcaster. It was possible to conclude that there was no highlight to a presenter who represented "the face" of each news program, but the work in home office emphasized the possibility of approaching viewers by highlighting the intimacy of journalists through the exposure of their homes.
