Estrutura de conteúdos educativos para TV Digital: um modelo de referência

This paper proposes a model of educative content structuring for interactive digital television programs. Its intent was to provide references for collaborative production processes and content organization in learning networks associated with university and educative television broadcasting services. The model defines terms, actors, events, environments, as well as content categories, classes and attributes, indicating criteria for their synchronic or asynchronic association in a dynamic television schedule. The model is presented in both descriptive and visual formats, with the use of conceptual maps. The results indicate that interactive use of digital television in education requires systematic content models covering communitarian participation in both media production and distribution processes, in order to enhance learning instruments beyond vertical, hierarchical and centralized communication sustained by traditional broadcast channels.

Gamificação: abordagem e construção conceitual para aplicativosem TV Digital Interativa

The deployment of Digital TV in Brazil opens up space for the development of educative content based on the concepts of t-learning and edutertainment. The study proposes the application of the gamification as a link of communication to encourage and modify the users’ behavior. However, bumps into itself on the conceptual problem, once the literature brings several definitions that vary according to the application context. The objective this study, exploratory, is to propose a conceptual approach, in order to build a delimited concept that substantiates the gamification system in Interactive Digital TV.

As possibilidades interativas do telejornalismo na TV digital aberta no Brasil

This paper presents proposals for the use of interactivity in the telejournalism in an open television broadcaster and the consequences of this use. The issues raised here go beyond technical issues and also addresses issues of theoretical field. The fundamental purpose of this paper is to present interactive possibilities in television journalism as a way of providing this television format tools to keep up with technological changes in the field of production and sharing news. However, by using these tools, the television news is enabling reversal of two important hypotheses that describe the analog television journalism: Scheduling Hypothesis and the Spiral of Silence. To reach your main goal we used a theoretical framework relevant to the issues addressed here and a survey of some interactive applications for digital television developed specifically for TV newscast. From this instrument, we selected two sets of interactive features that can be employed, in general, newscasts, and how these features relate to the hypotheses of Scheduling and Spiral of Silence.

Gamificação: modelagem de conteúdos para programas e aplicativos educativos no ambiente da TV digital interativa

With the deployment of Digital TV in Brazil, there is a need to foment the development and production of interactive audiovisual quality content, especially for programs that present educational messages from the entertainment concept - defined as Edutertainment. The objective of this study is to propose application of the gamification as a link of communication to encourage and modify user behavior, through a narrative that encourages intrinsic motivation for learning and entertainment in this media. This paper points out that there are few models of screenplays for applications production, particularly educational, with simultaneous interactive applications for television flow or complementary programming content offered. For this reason, a special attention is given to the screenplay, by virtue of inserting in its construction, the elements that make up the mechanics and dynamics of games. As a result, is shown the entry "Gamification-iDTV", which defines these two scenarios, as well as the development of a modeling methodology of a content and process, supported by conceptual maps, wireframes and roadmaps, substantiating the conception and elaboration of screenplay's prototype with elements of gamification for educational programs and its interaction applications.

An Architecture for End-User TV Content Enrichment

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.

MHP Oriented Interactive Augmented Reality System for Sports Broadcasting Environments

Television and movie images have been altered ever since it was technically possible. Nowadays embedding advertisements, or incorporating text and graphics in TV scenes, are common practice, but they can not be considered as integrated part of the scene. The introduction of new services for interactive augmented television is discussed in this paper. We analyse the main aspects related with the whole chain of augmented reality production. Interactivity is one of the most important added values of the digital television: This paper aims to break the model where all TV viewers receive the same final image. Thus, we introduce and discuss the new concept of interactive augmented television, i. e. real time composition of video and computer graphics - e.g. a real scene and freely selectable images or spatial rendered objects - edited and customized by the end user within the context of the user's set top box and TV receiver.

A IMAGEM E A COMPOSIÇÃO VISUAL NA TV DIGITAL

O trabalho aborda questões sobre a produção e composição da imagem em alta definição na TV Digital HDTV. Por meio dos dados levantados na literatura específica, impressa e eletrônica, e com entrevistas com profissionais da área e observações da programação disponível em HDTV na cidade de São Paulo puderam ser analisadas as imagens e composição visual que advém com a TV Digital de alta definição e interativa. Para tanto, a produção da imagem em alta definição precisa atender a dois tipos de público: o que assiste a transmissão digital e o que ainda continuará assistindo no sistema analógico com baixa percepção para os detalhes visuais. Os resultados demonstraram duas questões fundamentais e interdependentes: as práticas de produção, materiais cenográficos e processos de composição dos elementos da imagem precisam ser atualizados segundo as novas características tecnológicas e que o processo de implantação da TV Digital no Brasil deve ser revisto, com correções de prazos e das políticas adotadas sob o risco de se atrasar todo o processo de produção de conteúdo e da imagem em alta definição para este suporte.

A TV digital e o setor industrial tecnológico brasileiro

O presente estudo disserta sobre o papel da indústria, com foco nos fabricantes de televisores e sua participação na implantação e desenvolvimento da TV Digital no Brasil, como os primeiros atores desse cenário a apontar o norte para a viabilização de um modelo de negócio para a Televisão Digital (TVD) e Televisão Digital Interativa (TVDI): a TV Conectada e a TV Inteligente. Faz um levantamento histórico do tema desde o Governo FHC, passando pelo Governo Lula até o atual Governo Dilma. O texto apresenta os desafios técnico, político e econômico dessa implementação. Pretende identificar os acertos e enganos dos atores envolvidos nesse cenário, montado para a implementação do sistema digital da TV brasileira. Ressalta os interesses, nem sempre harmônicos, de todos os envolvidos: do capital, com foco no lucro; do governo, com seus acordos políticos, muitas vezes contrapondo ao cumprimento de seu papel de representante dos interesses da maioria da população brasileira; e da dinâmica científico tecnológico-industrial, que necessita de campo fértil, propício e contínuo para se desenvolver.(AU)

Inclusão via TV digital interativa brasileira: um estudo de caso no estado do Maranhão

Este trabalho discorre sobre o processo de implantação da TV digital interativa no Brasil, tendo como estudo de caso o estado do Maranhão e foca as possibilidades de inclusão social e digital em regiões com fragilidades de prestação de serviços públicos como Previdência Social, atendimento médico, bancário e de ensino a distância. Para tanto, aborda políticas públicas que conduziram ao SBTVD Sistema Brasileiro de Televisão Digital no país. O estudo apresenta as discussões na esfera pública e privada com a participação de organizações reconhecidamente qualificadas dentro e fora do país. Mostra também o complexo processo de articulação governamental com entidades da indústria eletroeletrônica e de grupos de telecomunicações privados instalados no Brasil, bem como a resistência de radiodifusores do setor privado em adotar o modelo proposto pelo Decreto 5.820/06 que prevê distribuição e acesso gratuito da população a serviços públicos essenciais por meio da televisão aberta. As consequências refletidas na permanência do atraso e baixo desenvolvimento do estado do Maranhão abrem possibilidades de superação com os novos programas disponibilizados pela Secretaria de Inclusão Digital (SID), do Ministério das Comunicações para responder à enorme demanda que priva regiões do Brasil como o Maranhão de desenvolvimento social e inclusão digital.

TV DIGITAL E EAD POSSIBILIDADES, LIMITES E TENSÕES

Essa pesquisa discorre sobre possibilidades e entraves na aplicação do Sistema Brasileiro de Televisão Digital Interativa Terrestre (SBTVDI-T) nos Sistemas de Ensino a Distância (EAD) de nível superior. Justifica-se a importância da pesquisa pelas especulações que o nascimento do SBTVDI gera quanto a suas contribuições tecnológicas, algumas delas voltadas especificamente para o sistema de ensino. Objetiva-se coletar e analisar as possibilidades e impasses da nova tecnologia em relação a EAD de nível superior, considerando a visão dos profissionais envolvidos na implantação da nova TV brasileira. A metodologia da dissertação está composta de pesquisas documentais e bibliográficas que fundamentam a televisão digital brasileira, interatividade e EAD relacionadas com entrevistas em profundidade com os desenvolvedores e pesquisadores da nova tecnologia, sistematizadas pelo método da análise interpretativa. Concluí-se que TV digital pode ser aliada à EAD, independente do grau de ensino, mas ainda é inconclusiva sua participação específica na convergência entre as tecnologias da informação e da comunicação (TIC) disponíveis.

Exploring the adoption of interactive digital television services as a retail shopping platform

The aim of this research is to consider the possible effect of an emerging technology platform on the uptake of online shopping: interactive (digital) Television (iTV), which enables viewers to select a variety of viewing options, publicity materials, games, entertainment and more recently shopping. An augmented version of the original TAM is applied to this study. Two new constructs are considered namely access and awareness together with perceived ease of use, perceived usefulness, perceived enjoyment and security. The results show that indeed the augmented TAM can be used as a predictive model for the adoption of iTV as an online shopping platform. It is concluded that access, perceived ease of use, perceived enjoyment and perceived usefulness are significant factors to determine the consumers’behavioural intentions towards the use of digital TV as a new shopping platform. However, awareness and security are considered to be insignificant with no effect on consumers’ behavioural intentions towards the new shopping medium.
