A televisão nos dias atuais tem sofrido inúmeras inovações tecnológicas nos campos das transmissões multimídia, qualidade audio-visual e diversidade de funcionalidades. Entretanto, esta essencialmente mantêm sua característica de fornecer informações de forma quase que instantânea à população. O ambiente atual da televisão digital é caracterizado pela coexistência de inúmeros dispositivos capazes de oferecerem uma experiência televisa, associando-se computadores pessoais, smartphones, tablets e outros eletrônicos de consumo. Ainda, pode se incluir a este cenário a disponibilidade de inúmeras redes de transporte de dados tais como a radiodifusão, satélite, cabo e redes em banda larga. Este cenário diversificado, em termos de dispositivos e redes, é denominado de cenário de televisão digital híbrida, a qual destaca-se a interação do expectador com os diversos dispositivos. Estes cenários, por sua vez, motivam o desenvolvimento de tecnologias que permitem o aperfeiçoamento da pervasividade e dos meios pelos os quais os aplicativos possam ser suportados em diferentes plataformas. Este trabalho propõe ambientes interoperáveis envolvendo a televisão digital interativa e outros eletrônicos de consumo, aos quais foram realizados estudos e experimentos para se observar diferentes técnicas de sincronização e comunicação entre plataformas de interatividade para a televisão digital híbrida. Os resultados apontam para a possibilidade de cenários interoperáveis envolvendo o uso de marcadores e também recursos de redes e serviços TCP/IP, levando em consideração a eficiência e eficácia nos diferentes métodos. Conclui-se que os resultados odem motivar o desenvolvimento de cenários diferenciados envolvendo a televisão digital interativa e dispositivos de segunda tela, o que incrementa a interatividade e as formas de entretenimento.

In recent years, Twitter has become one of the most important microblogging services of the Web 2.0. Among the possible uses it allows, it can be employed for communicating and broadcasting information in real time. The goal of this research is to analyze the task of automatic tweet generation from a text summarization perspective in the context of the journalism genre. To achieve this, different state-of-the-art summarizers are selected and employed for producing multi-lingual tweets in two languages (English and Spanish). A wide experimental framework is proposed, comprising the creation of a new corpus, the generation of the automatic tweets, and their assessment through a quantitative and a qualitative evaluation, where informativeness, indicativeness and interest are key criteria that should be ensured in the proposed context. From the results obtained, it was observed that although the original tweets were considered as model tweets with respect to their informativeness, they were not among the most interesting ones from a human viewpoint. Therefore, relying only on these tweets may not be the ideal way to communicate news through Twitter, especially if a more personalized and catchy way of reporting news wants to be performed. In contrast, we showed that recent text summarization techniques may be more appropriate, reflecting a balance between indicativeness and interest, even if their content was different from the tweets delivered by the news providers.

Canal 9 –o Nou, como se llamó en su última etapa– con su carácter ejemplarizante para el resto de autonómicas, se convierte en el objeto de estudio perfecto para los investigadores en comunicación. El trabajo se centra en la última etapa de RTVV, bajo la influencia de un nuevo estatuto legal, que dotaba a la televisión de herramientas presuntamente facilitadoras de la pluralidad en los informativos. Mediante un análisis cualitativo basado en entrevistas semiestructuradas a un panel de expertos, intentamos averiguar si se produjo en ese tiempo un cambio apreciable en la redacción de Canal 9, combinado con un cambio de talante en la gestión de la empresa. La conclusión, con los matices que desarrollamos en el texto, es que sí que se produjo una apertura en esa fase, que desgraciadamente fue abortada por el cierre precipitado. La eliminación de la emisora autonómica provocó un efecto destructivo en cadena en el sistema audiovisual valenciano que aún no se ha superado.

La próxima reapertura de la radiotelevisión valenciana, teniendo en cuenta el fracaso en la gestión de RTVV durante años, suscita interrogantes sobre cómo se está desarrollando el proceso de creación del nuevo ente público. Cuáles son las medidas que se están llevando a cabo para garantizar la independencia política de la nueva corporación y evitar los errores del pasado. El objetivo de este estudio consiste en comparar los mecanismos y herramientas con los que contaba RTVV y con los que se dotará al nuevo ente, ya que a priori marcarán la diferencia entre ambos. En este sentido, la investigación se fundamenta en el análisis de contenido de la legislación tanto de RTVV como de la futura Corporación Valenciana de Medios de Comunicación, teniendo como referencia el informe de expertos Bases per a la renovació de l’espai comunicatiu valencià i la restitució del servei públic de radiotelevisió. Finalmente, se ha podido concluir que algunas herramientas de autorregulación interna propuestas hoy, ya formaban parte de la antigua RTVV. Estos organismos no cumplieron su cometido debido a la politización de los mismos, que en definitiva fue la principal causa de su declive. No obstante, también existieron carencias en cuanto a regulación externa, y que en esta nueva etapa se están incluyendo para aumentar las garantías de independencia y cumplimiento deontológico profesional.

From the Introduction. The Media Sector has experienced a technological revolution in the last 15 years. Digital encoding of television signals made possible a more efficient use of the radiospectrum. Digital terrestrial television (hereinafter, “DTT”) allows now for the reception of a significant number of free-to-air channels.1 Moreover, the use of new transmission platforms (hereinafter,“platforms”), namely cable and direct-to-home satellite (hereinafter, “DTH”) paved the way for the arrival in Europe of pay-TV operators, which finance their activities mainly via subscription fees. This changing technological landscape is subject to further evolution in the near future, as incumbent telecommunications operators become increasingly interested in making available broadcasting content2 as part of their broadband offer and 3G mobile handsets can be used for the reception of TV signals....The present paper seeks to ascertain whether the Commission “regulatory approach” towards the exclusive sale of premium content is a sound one, in particular in view of the constant technological evolution outlined above. The assumptions underlying landmark Commission decisions will be compared with recent developments of the media sector in Italy. In the NewsCorp./Telepiù case, decided in 2003, the Commission imposed very strict conditions to allow the merger giving birth to Sky Italia, on the assumption that the operation created a lasting near-monopsony in the different upstream markets for the acquisition of premium intervened against the media conglomerate Mediaset (which controls, inter alia, the main three private free-to-air channels in Italy) for an alleged abuse of dominant position.17 In fact, and contrary to the forecasts made by the Commission, Mediaset was in a position to acquire the broadcasting rights of the main Italian football teams, thereby excluding the incumbent (and near-monopolist) pay-TV operator, Sky Italia. This may go to show that the reality of the sector is more complex and evolves faster than one may infer from the Commission practice, thus putting into question its stance regarding exclusivity. The experience of the evolution of the Italian media sector will be used as the starting point for the evaluation of alternative regulatory options.

The independence of the mass media has been regularly restricted over the past two years in Ukraine. Following a period of relative freedom in 2005–2010, the scope of direct and indirect government control of the press has increased, cancelling out the achievements of the Orange Revolution in this area. The press in Ukraine is less and less able to perform its role as watchdog on the government and politicians and as a reliable source of information on the situation in the country to the public. This is mainly due to: (1) the concentration of the most important mass media in the hands of Ukraine’s most powerful oligarchs, whose business interests depend on the government; (2) the use of the press as instruments in political and business competition; (3) the ruling class’s subordination of the institutions which supervise the press; (4) repression used against media critical of the government and (5) the lack of an independent public broadcasting corporation. As a consequence, the press has hardly any impact on the political processes taking place ahead of the parliamentary election scheduled for 28 October. This is also an effect of a passiveness present in the Ukrainian public, who are tired of politics and are focused on social issues. Cases of abuse or corruption scandals revealed by the press do not provoke any response from the public and are rarely investigated by the public prosecution authorities. The more popular a given medium is, the more strongly it is controlled by the government. At present, television has to be recognised as the least reliable of the mass media. In turn, Internet news journals are characterised by the greatest pluralism but also have more limited accessibility. The political conditions in which the mass media operate in Ukraine lead to various forms of pathology. The most serious of them are censorship by the owners and self-censorship performed by journalists, and a great share of political advertorials. As the parliamentary election is approaching, the pathologies of the Ukrainian media market have been showing up with greater intensity.

Confronted by the current refugee crisis, most Member States are turning inwards. But migration will continue to rise in the future. Given that migration is an unstoppable trend, the EU has everything to win from turning this crisis into an opportunity for its own citizens and economy, for the refugees and migrants it hosts and for their countries of origin. The manner in which the EU addresses this challenge will truly prove if it can live up to its founding principles of human dignity, solidarity, freedom, democracy and equality. This policy brief summarises European measures taken in the last few months and proposes four key actions to create a well-framed European migration policy: effectively implementing the principle of solidarity and fair-sharing of responsibility between Member States; creating more legal entry and integration channels; addressing the root causes of migration; and broadcasting a constructive and positive narrative on migration.
