La Televisió ja no serà tan ximple

La televisió molt aviat podria deixar de ser aquella caixa tonta davant la qual estàvem obligats a empassar-nos allò que només ella ens proposava. Els primers de descobrir una nova forma de fer servir la tele seran els veïns del Pla de l'Estany, que la podran utilitzar per sol·licitar hora al metge, pagar impostos o demanar informacions diverses. L'Easy de la UdG i el Consell Comarcal del Pla de l'Estany signaran el proper 7 de juny un conveni per a desenvolupar aplicacions d'intel·ligència artificial a través de la xarxa de la televisió digital terrestre (TDT)

La TDT impulsa la multiplicación de canales infantiles.

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). The emergence of this vast multiplatform digital landscape impels to know of individual and complementary use of these devices with ubiquitous nature or not. The widespread adoption of smartphones, tablets and other connected devices via internet makes users / consumers of these devices to feed a diet based on a constant flow of digital content across different platforms. The objective of this paper is to describe the role of television in the context of the Media Ecology which is established by the "digital omnivores" a new group of consumers whose name, according Canavilhas (2013, p.03), "is related with the platforms that consumers use to access the Internet, but also to the type of individual and multiplatform consumption they do.”

Valoración de los estudiantes de la ULPGC sobre la creación de un canal propio de televisión

[ES]Son muchas las universidades en todo el mundo que han apostado, con mayor o menor éxito, por utilizar las tecnologías digitales de televisión en los diferentes campos de la enseñanza mediante el uso de los portales corporativos de televisión y de Internet.

Serviço de videochamada utilizando o padrão o HbbTV: myPhoneOnTV

Nos últimos anos tem-se verificado que a população portuguesa está cada vez mais envelhecida. Este fator agrava-se em ambientes rurais, onde a desertificação populacional é mais frequente, derivado, entre outros, da migração da população mais jovem para os grandes centros urbanos, em busca de melhores condições de vida. Tendo como consequência a exclusão social da população residente nestas zonas. O reduzido foco populacional das zonas rurais não é um fator atrativo para as entidades que realizam investimentos em serviços e infraestruturas tecnológicas, devido ao retorno financeiro obtido não ser, à partida, rentável. Levando a uma exclusão tecnológica de quem reside nestas zonas. Este fator, agrava-se na população sénior dado que raramente são estimulados a interagir com a tecnologia. Com o objetivo de contribuir para a melhoria desta problemática, combatendo simultaneamente os dois tipos de exclusões, tecnológica e social, propõem-se através desta dissertação, um serviço de videochamada, baseado no conceito do padrão Hybrid Broadcast Broadband TV (HbbTV). Um dos fatores considerados, durante o estudo deste serviço, foi a barreira tecnológica existente entre os idosos e a tecnologia. De modo a aproximar ambos, optou-se por aproveitar os conhecimentos que os idosos já possuem na utilização de equipamentos do seu quotidiano. Sendo a televisão, o equipamento selecionado para integrar no serviço de videochamada, permitindo ao idoso contactar facilmente com outras pessoas e serviços. Através da implementação de um protótipo e dos resultados obtidos, conclui-se que o serviço desenvolvido é uma solução válida para combater a problemática apresentada, contribuindo positivamente para a redução da exclusão social e da iliteracia tecnológica

Over the Air Download for Digital Television Receivers Upgrade

Over the air download is an important feature for terrestrial digital television systems. It provides a cheaper option for DTV receiver manufacturers to provide bug fixes and quality improvements to their products, allowing a shorter time to the market. This paper presents a mechanism proposal of an over the air download software update for the Brazilian system. This mechanism was specified considering the Brazilian DTV over the air download specifications, but it was extended considering efficiency, reliability and user transparency as requirements for software update. A proof of concept was implemented on a Linux based set-top box. The mechanism is divided into five main functional parts: download schedule, packets download, packets authentication, installation and error robustness. Some analyses were conducted upon the implementation considering the following criteria: download robustness and maximum downloading rate. (1)

The migration towards Digital Terrestrial Television: challenges for public policy and public broadcasters

This paper initially identifies the main transformations of the television system that are caused by digitalization. Its development in several broadcasting platforms is analyzed as well as the particular obstacles and requirements that are detected for each of them. Due to its technical characteristics and its historical link to the public services, the terrestrial network requires migration strategies different from those strictly commercial, and public intervention might be needed. The paper focuses on such migration strategies towards DTT and identifies the main issues for public intervention in the areas of the digital scenario: technology, business and market transformation and the reception field. Moreover, it describes and classifies the challenges that public broadcasters should confront due to digitalization. This paper finally concludes that the leadership of the public broadcasters during the migration towards DTT is an interesting tool for public policy. The need for foster the digitalization of the terrestrial platform and to achieve certain social and public goal besides the market interest brings an opportunity for public institutions and public broadcasters to work together. That leading role could also be positive for the public service to face its necessary redefinition and reallocation within the digital context.

Consistency and change in Finnish broadcasting policy : the implementation of digital television and lessons from the Canadian experience

Konsistens och förändring i finländsk etermediapolitik. Implementering av digital television och en jämförelse med Kanada Avhandlingen handlar om hur det finländska televisionssystemet förändrades i slutet av 1990-talet från en nationell institution till ett dualistiskt system som präglas av stark marknadsorientering. Syftet med avhandlingen är att förstå på vilket sätt en så snabb förändring kunde ske och analysera de institutionella faktorerna bakom utvecklingen. På teoretisk nivå diskuteras tesen om det nära sambandet mellan statliga politiska institutioner och rundradioverksamhetens institutioner. Avhandlingen består av två fallstudier. Den första sätter fokus på de första åren av den finländska televisionens digitaliseringsprocess som startade med starka industriell-nationalistiska motiveringar. Analysen, som baserar på offentliga dokument, sträcker sig framtill hösten 2001 då de digitala televisionssändningarna startade och regeringspropositionen om den nya kommunikationsmarknadslagen lämnades till riksdagen. Dessa policy-processer analyseras som en ”marknadisering” av de traditionella styrningsprinciper och idéer gällande finländsk rundradioverksamheten. En jämförelse mellan Finlands och Kanadas nationella rundradiopolitik gör att man kan koppla slutsatserna till den internationella utvecklingen. Jämförelsen visar hur kommunikationspolitiska linjen i de två länderna har kommit att likna varandra trots att ländernas tv-system och deras styrordningar är mycket olika. Exemplet med Kanada visar att den särskilda teknologin inte är viktig utan snarare de kommersiella intressen som står bakom och som beslutsfattare gärna döljer i en nationalistisk retorik. Studien visar att det är viktigt att beakta vilken tyngd man i politiken ger de två sidor som rundradioverksamheten består av: sändningsteknologin och verksamheten som en speciell kulturform. Nationalstatens handlingsutrymme minskar inom fältet om målet är att vara framgångsrik i konkurrensen i den nya internationella ekonomin. Enligt de nyliberalistiska principer som det politiska systemet överlag har tillägnat sig det är önskvärd men också helt inhemska institutionella traditioner och praxis som följdes i den finländska digitaliseringsprocessen främjade utvecklingen som ledde till att nästan alla ursprungliga nationella syften föll sönder.

The potential of digital interactive television for the provision of healthcare and wellness services

The potential of digital interactive television (iDTV) to promote original services, formats and contents that can be relevant to support personal health care and wellness of individuals, namely elderly people, has not been yet fully explored in the past. Therefore, in a context of rapid change of the technological resources, in which the distribution and presentation of content comes associated with new platforms (such as digital terrestrial TV and IPTV), it is important to perceive the configurations that are being developed for interactive digital TV (iDTV) that may result in relevant outcomes within the field of healthcare and wellness, with the aim of offering complementarity to the existing services and contents made available today via the traditional means and media. This article describes and discusses the preliminary results of the first part of the research project iDTV-HEALTH: Inclusive services to promote health and wellness via digital interactive television. These first results suggest that iDTV solutions may represent a real contribution to delivery healthcare and wellness to the target population, namely as a supplement to health services provision.

Drivers and barriers to digital television adoption in Portugal: the perspectives of the TV viewers and other main stakeholders

To understand what are the most significant factors for digital TV adoption by the Portuguese population in the switchover context is the main goal of the research project here presented. In April 26, 2012, the analogue terrestrial television switchoff is planned to occur in Portugal, according to the schedule published by the national telecommunication regulator Anacom. Digital terrestrial TV was launched in the country in April 2009, making Portugal one of the countries with a more ambitious schedule – or risky, depending on the perspective - for the full transition from analogue to digital terrestrial television. In this paper we will start by presenting the research project’s objectives, theoretical framework and research design. Next, we will present first results of the project focused on the barriers and drivers to digital TV adoption from two of the empirical studies which integrate it, namely, the quantitative inquiry administered to a representative sample of the Portuguese population and interviews with main stakeholders in the area of digital TV in Portugal. The perspectives of the television viewers are compared with other main stakeholders in this process. The paper will be concluded with a brief discussion of these results and a brief enumeration of next steps for the project.

Incentives and Barriers to the Adoption of Digital Terrestrial Television in Portugal: Perspectives of the stakeholders involved in the transition process

The success of the transition from analogical terrestrial television to digital terrestrial television – process also known as switch-over – requires the identification of barriers and drivers among the impacted population. Therefore, the study in which this article is based had as main purpose to understand exactly what are those barriers, in order to produce a valid contribution to the several decision makers, and to be able to contribute to a more inclusive television, accessible and transversal to the whole of the population. In that sense, one of the phases of the project consisted in several interviews to key stakeholders in the transition process, the results of which and subsequent recommendations are presented in this article.
