This work had as objective the development of a prototype of educational content, as an experimental process, making use of resources from Interactive Digital TV. The characteristics of interactive digital terrestrial television are presented, in the form of a media mode capable of performing as a complementary source to education. The methodology used is composed of four phases: deduction, analysis, induction and synthesis. Its conception takes as issue the expressed need stated by UNESCO to use ICT (Information and Communications Technology) towards education, as well as the possibility of applying digital television in an educational process. The content is structured in the form of a quiz, a type of question-answer game as an informal way of education for high school students. The prototype developed in this work is presented as a structural script and map, taking into account the necessary activities and routines to put it into operation in the tested environments, eclipse, virtual set-top-box and Developer Box. The practice of prototyping was carried out in NCLua, based on middleware Ginga. As a result, we concluded that Ginga offers enough support to carry out the task, providing characteristics of interaction to publish the proposed content, at the moment of the actual practice.

In Brazil, the discussion about thereplacement of analog television signals to digitaland its impact on society, in media companies andgovernment began in the 90s. Embryonic steps towardsdigitalisation of the television signal ground were thegovernment of Fernando Collor de Mello (1990-1992),with advances during the government of FernandoHenrique Cardoso (1994-2001) and in the governmentof Luiz Inacio Lula da Silva (2002). The academy startsthe discussion in 1996. This article aims to bring to lightthe results obtained from the survey Digital television:a historical perspective , which received the supportof CNPq for funding of two scholarships for scientifi cinitiation between August 2008 and July 2009. Theproject sought to identify what has been published onthe subject in the fi eld of Social Sciences and from threemacrodescritores (information management, publicpolicy and value chain), providing the li ing of a virtualcollection Zotero bibliographic innovative platform.The mapping serves to show the growing interest anddevelopment of research in the country during theperiod - when the number jumped to three works inthe fi rst seven years (1995-2001) to 198 in the last sevenyears (2002-2008). The research sought to identify themajor authors and works related to digital televisionand published in the country. The survey took intoaccount books, articles published in books, journals,Annals of Compós and Intercom, and dissertations andtheses. Data and refl ections on the survey are containedin this communication.

This article presents considerations concerning the interaction between communication and digital platforms and applications developed to perform computerized climate monitoring and issue alerts about natural disasters. From work in the Center for Integrated Natural Disaster Alert (CIADEN), which processes meteorological data provided by Platform Monitoring, Analysis and Warning TerraMA2 designed by the National Institute for Space Research (INPE) to conduct monitoring and fi ring warning about climate risk environment, we propose the expansion of interactivity with the various possibilities of digital communication available today for signifi cant portion of society. On another front, the CIADEN has articulated teaching and research on climate monitoring and warning of natural disasters, weather, and geoprocessing environment, involving teachers and students both in school and in higher and technical.

This article presents a study on the concept of social TV and the user’s experience. We made a literature review in search of the several meanings and features given to the subject. We have analyzed the aspects that express changes in the field, beginning with the TV set connected to the internet, which allows users to new experiences of socialization, previously available only in other devices. This new scenario provides a new platform called “TV everywhere”, the ubiquitous television that is everywhere, regardless of location, time or space. We have researched the origin of social TV and the process that altered the old television model. Finally, we propose a new term to express such changes regarding social television: “Social TV”, representing the user’s experience through the convergence between television and the Internet, shared locally and remotely through any technological means.

his article is the result of an empirical research on the technology and market development resulting from the deployment of Digital TV in Brazil. Two aspects were selected to discuss the proposed question: the economic and political motivations that led to the digitization of broadcast TV in Brazil and the preliminary analysis of the effects on popularization of cyberculture in the Brazilian audiovisual scenario, changes can be observed in the production, dissemination and enjoyment of audiovisual content. For the development of the analysis the following theoretical and analytical tools were used: Theory Empirical Approach (Wolf, 1987), the Cultural Studies (Zallo, 1988; 1992), the digitalization media process (Lemos), the transition from television to cyberculture studies (Manovich, 2005) and (Fechine, 2013).

Wireless networks rapidly became a fundamental pillar of everyday activities. Whether at work or elsewhere, people often benefits from always-on connections. This trend is likely to increase, and hence actual technologies struggle to cope with the increase in traffic demand. To this end, Cognitive Wireless Networks have been studied. These networks aim at a better utilization of the spectrum, by understanding the environment in which they operate, and adapt accordingly. In particular recently national regulators opened up consultations on the opportunistic use of the TV bands, which became partially free due to the digital TV switch over. In this work, we focus on the indoor use of of TVWS. Interesting use cases like smart metering and WiFI like connectivity arise, and are studied and compared against state of the art technology. New measurements for TVWS networks will be presented and evaluated, and fundamental characteristics of the signal derived. Then, building on that, a new model of spectrum sharing, which takes into account also the height from the terrain, is presented and evaluated in a real scenario. The principal limits and performance of TVWS operated networks will be studied for two main use cases, namely Machine to Machine communication and for wireless sensor networks, particularly for the smart grid scenario. The outcome is that TVWS are certainly interesting to be studied and deployed, in particular when used as an additional offload for other wireless technologies. Seeing TVWS as the only wireless technology on a device is harder to be seen: the uncertainity in channel availability is the major drawback of opportunistic networks, since depending on the primary network channel allocation might lead in having no channels available for communication. TVWS can be effectively exploited as offloading solutions, and most of the contributions presented in this work proceed in this direction.

This paper proposes an extension to the televisionwatching paradigm that permits an end-user to enrich broadcast content. Examples of this enriched content are: virtual edits that allow the order of presentation within the content to be changed or that allow the content to be subsetted; conditional text, graphic or video objects that can be placed to appear within content and triggered by viewer interaction; additional navigation links that can be added to structure how other users view the base content object. The enriched content can be viewed directly within the context of the TV viewing experience. It may also be shared with other users within a distributed peer group. Our architecture is based on a model that allows the original content to remain unaltered, and which respects DRM restrictions on content reuse. The fundamental approach we use is to define an intermediate content enhancement layer that is based on the W3C’s SMIL language. Using a pen-based enhancement interface, end-users can manipulate content that is saved in a home PDR setting. This paper describes our architecture and it provides several examples of how our system handles content enhancement. We also describe a reference implementation for creating and viewing enhancements.

Este trabalho pretende refletir sobre a qualidade dos programas dedicados aos jovens na TV Cultura de São Paulo. A emissora pública, premiada nacional e internacionalmente pela qualidade da programação infantil e que fideliza muito bem as crianças, perde mais de 80% da audiência quando passa da faixa infantil para a dos adolescentes, entre 12 e 17 anos. O objetivo é identificar os motivos da queda de audiência e buscar respostas positivas para fidelizar o jovem na Cultura, emissora preocupada em formar telespectadores mais reflexivos. Foram realizadas quinze entrevistas abertas com estudantes adolescentes do segundo grau da Fundação Instituto Tecnológico de Osasco, grande São Paulo, que foram telespectadores assíduos da Tv Cultura quando crianças. A pesquisa procurou identificar as causas que levam o telespectador jovem a trocar a Cultura por outros canais de televisão. Verificou-se que o jovem busca não só outras emissoras, mas especialmente outras mídias digitais, games e internet e dão preferência à comunicação com interatividade.(AU)
