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.

Subtitling as a pedagogical tool for language teaching in journalism

This study was designed to present and discuss some results produced by a research involving the use of English subtitles of some news videos from the webiste Reuters.com (http://www.reuters.com) with pedagogical reasons in a Brazilian context (Academic English for Journalism). We have developed the research during two semesters at UNESP (Universidade Estadual Paulista Júlio de Mesquita Filho). The professor in charge of the study has chosen the students of Journalism as the audience to whom the videos were presented. The assumptions of many theorists and experts in Audiovisual Translation were adopted as our Theoretical Sources. The first step of the study was the assessment of the syllabus of each course. This was very helpful as a guidance in order to choose the most relevant and interesting videos for students. After the evaluation of academic and professional interests, we chose some videos to insert appropriate subtitles, according to some strategies suggested by Panayota Georgakopoulou and Henrik Gottlieb. Finally we presented the videos during the English classes. At the first time, they were presented without subtitles just to notice the comprehension level of the students. After that, the videos were presented with English subtitles. As we first assumed, the students haven’t had the whole comprehension of specific details during the first presentation, they have just used their previous knowledge and the visual aids to help them in a superficial understanding of the news. As the subtitles appear, the process of communication was finally accomplished.

A estética da imagem na TV digital

This text reflects on the techniques and the process of image production and its artistic composition to digital television in high defini- tion, whereas the 4:3 and 16:9 formats will exist until shutdown of the analog signal. Within this period, consumers of television programming that have analog receivers will continue to see the images in 4:3 format. That fact determines that the productions in high definition, while capturing images with larger viewing area and have high contrast ratio (>1000:1) must be main- tain the elements of visual storytelling within the smallest area and with the contrast ratio of the analog tv (30:1), at the risk of distorting visually the messages produced by the directors.

Known as second screen, viewers interact simultaneously across these devices, sharing information about the programming on social networks, seeking additional information about the contents well aired, in addition to being likely to purchase products and services on platforms of mobile-commerce persuaded by the scheduling of programming through commercials. Given this, the aim of this article is to propose and prototyping an application visually in second screen with emphasis on business model with possible application on TV Unesp, where the viewer to interact with the programming through the application is exposed to previously scheduled ads, links to mobile-commerce and posts indicating purchase suggestions.

New Business Models And Editorial Exemption: A Study On Service Journalism Based On Ecommerce Operations

The paper presents and discusses business strategies based on the association from journalistic content to new commercial practices in digital media. We describe selected examples from Folha de S. Paulo and El País involving service guides, links and ecommerce advertisements. The employed method provides content analysis to illustrate how the search for new business models in journalism may conduct its commercial activities beyond the conventional sale of advertising and subscriptions, including a discussion on the challenges and implications of this practice. The hypothesis is demonstrated by describing operations for the sale of tickets, books, music, and films related to news features and service journalism contents. The text finally wonders and discusses how such commercial actions may affect editorial autonomy and publishing exemption.

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.

A TV no ecossistema dos onívoros digitais

A quick setup of the digital environment that occurs in these first decades of the twentyfirst century has involved the use of electronic devices for consume content both at home, at work and on the go (ComScore, 2011).

Uma mirada em dois projetos e concepções sul-americanas de TV pública digital: análise comparativa entre TV Brasil e Canal 7 Argentina

Esta tesis es resultado de un intenso trabajo de investigación realizado de agosto de 2014 a agosto de 2015, con financiación de la Fundação de Amparo à Pesquisa do Estado de São Paulo (Fapesp). El objetivo se centró en la realización de un análisis, aunque preliminar, del papel de la TV pública con tecnología digital, como también de las tendencias, desafíos y perspectivas para consolidarla, tanto en Brasil como en Argentina, países con diversas similitudes en contextos económicos, sociales, políticos y culturales. Para cumplir los objetivos, estudiamos los recientes proyectos gubernamentales de televisión pública en los dos países suramericanos. El gobierno argentino invirtió en modernización en Canal 7 (antiguo Argentina Televisora Color-ATC), una emisora de casi seis décadas de funcionamiento, que ha sido prácticamente refundada a partir de los investimentos públicos del gobierno nacional argentino, realizados para digitalizar los sistemas de transmisión y de recepción de televisión abierta. El nuevo Canal 7 pasó a servir de cabeza de red del sistema de televisión pública de Argentina. En Brasil, el gobierno creó a fines del 2007, la Empresa Brasil de Comunicación (EBC), estructura administrativa que opera la red de televisión pública de TV Brasil. Ambos proyectos prometen construir y gestionar sistemas nacionales abiertos, modernos y competitivos de TV Pública Digital Abierta (TVPDA). Esta tesis también describe y compara de modo sucinto el desarrollo histórico de la radiodifusión - evidenciando la televisión como una plataforma en permanente disputa comunicacional, política, ideológica, publicitaria, cultural y económica -, tal como los modelos de televisión pública y comercial en cada uno de los dos países analizados (no entiendo la expresión). La estudiante de periodismo pretende confrontar el desarrollo de una estructura nacional de televisión pública iniciada en el...

Video Quality Assessments on Digital TV and Video Streaming Services Using Objective Metrics

There is a wide range of telecommunications services that transmit voice, video and data through complex transmission networks and in some cases, the service has not an acceptable quality level for the end user. In this sense the study of methods for assessing video quality and voice have a very important role. This paper presents a classification scheme, based on different criteria, of the methods and metrics that are being studied in recent years. This paper presents how the video quality is affected by degradation in the transmission channel in two kinds of services: Digital TV (ISDB-TB) due the fading in the air interface and video streaming service on an IP network due packet loss. For Digital TV tests was set up a scenario where the digital TV transmitter is connected to an RF channel emulator, where are inserted different fading models and at the end, the videos are saved in a mobile device. The tests of streaming video were performed in an isolated scenario of IP network, which are scheduled several network conditions, resulting in different qualities of video reception. The video quality assessment is performed using objective assessment methods: PSNR, SSIM and VQM. The results show how the losses in the transmission channel affects the quality of end-user experience on both services studied.

TV-L1 optical flow estimation

[EN] This article describes an implementation of the optical flow estimation method introduced by Zach, Pock and Bischof. This method is based on the minimization of a functional containing a data term using the L norm and a regularization term using the total variation of the flow. The main feature of this formulation is that it allows discontinuities in the flow field, while being more robust to noise than the classical approach. The algorithm is an efficient numerical scheme, which solves a relaxed version of the problem by alternate minimization.
