Social TV: definição sobre a experiência do usuário

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.

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.

A Copa do Mundo de 2010 entre o jornalismo e o entretenimento: uma análise do Central da Copa, da TV Globo

The proposed paper aims to understand and analyze how the sporting television journalism has changed in Brazil, affecting the coverage of major events like the World Cup. The impact of these changes are reflected in the use of interactivity, entertainment and presentation of news, in pictures and on television news programs inserted in Brazilian TV News. The study proposes to analyze, through theories of journalism and content analysis, as two seemingly opposing concepts (journalism and entertainment) were put into perspective by the Central Cup television program, aired during the year 2010 by Globo television, on the occasion of the World Cup in South Africa.

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.

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.

Social TV Unesp: proposta de aplicativo em segunda tela com ênfase em modelo de negócios para TV Universitária UNESP

The audiovisual market carefully observes a tendency in television consumption habit: viewers are increasingly watching television content while surfing the internet through mobile devices like tablets, smartphones and laptops. 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.

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.

Percepção do médico sobre pagamento por desempenho no gerenciamento de doenças cardiovasculares: o caso de uma operadora de plano de saúde

Desde os anos 50, os fatores de risco para as doenças cardiovasculares passaram a ser valorizados. O gerenciamento de doenças cardiovasculares (PGC) busca a construção da autonomia e melhoria da qualidade de vida dos pacientes. Em alguns países, para alcançar esses objetivos, tem sido apontada a utilização de programas de pagamento por desempenho (PPP) aos médicos como um dos elementos de melhoria nos processos e nos resultados dos pacientes e na condição de remuneração. O objetivo deste estudo é analisar o ponto de vista dos médicos sobre a implantação dos pagamentos por desempenho vinculados ao PGC em uma operadora de plano de saúde. Trata-se de investigação de caráter qualitativo, do tipo estudo de caso, apresentando entrevistas semiestruturadas com médicos participantes ou não do PGC, em setembro de 2009, tendo como referência as ações implantadas em 2008. Foram entrevistados 23 médicos (14 homens e 09 mulheres). Como resultado foi observado que o incentivo financeiro é reconhecido pelos médicos como importante, mas não determinante da inclusão de pacientes no PGC. O principal motivo apresentado foi a organização do cuidado, no qual o paciente é mais bem acompanhado e controlado, e o trabalho médico, avaliado segundo parâmetros preestabelecidos. O PGC e o PPP têm potencial de transformação do cuidado em saúde. O trabalho multidisciplinar e a maior produtividade nos atendimentos no consultório foram os principais efeitos positivos identificados. Outros estudos são necessários para acompanhar a evolução e os efeitos do pagamento por desempenho no trabalho médico.

Are prescribing doctors sensitive to the price that their patients have to pay in the Spanish National Health System?

[EN] Background This study aims to design an empirical test on the sensitivity of the prescribing doctors to the price afforded for the patient, and to apply it to the population data of primary care dispensations for cardiovascular disease and mental illness in the Spanish National Health System (NHS). Implications for drug policies are discussed. Methods We used population data of 17 therapeutic groups of cardiovascular and mental illness drugs aggregated by health areas to obtain 1424 observations ((8 cardiovascular groups * 70 areas) + (9 psychotropics groups * 96 areas)). All drugs are free for pensioners. For non-pensioner patients 10 of the 17 therapeutic groups have a reduced copayment (RC) status of only 10% of the price with a ceiling of €2.64 per pack, while the remaining 7 groups have a full copayment (FC) rate of 40%. Differences in the average price among dispensations for pensioners and non-pensioners were modelled with multilevel regression models to test the following hypothesis: 1) in FC drugs there is a significant positive difference between the average prices of drugs prescribed to pensioners and non-pensioners; 2) in RC drugs there is no significant price differential between pensioner and non-pensioner patients; 3) the price differential of FC drugs prescribed to pensioners and non-pensioners is greater the higher the price of the drugs. Results The average monthly price of dispensations to pensioners and non-pensioners does not differ for RC drugs, but for FC drugs pensioners get more expensive dispensations than non-pensioners (estimated difference of €9.74 by DDD and month). There is a positive and significant effect of the drug price on the differential price between pensioners and non-pensioners. For FC drugs, each additional euro of the drug price increases the differential by nearly half a euro (0.492). We did not find any significant differences in the intensity of the price effect among FC therapeutic groups. Conclusions Doctors working in the Spanish NHS seem to be sensitive to the price that can be afforded by patients when they fill in prescriptions, although alternative hypothesis could also explain the results found.
