Book Review: Public Service Media and Policy in Europe

Much has happened in the past fifty years, and the broadcasting system and in fact the entire media landscape have changed in many significant ways. Yet, the debate on the role of public service media and the involvement of the state in them still perseveres. It has indeed been reinvigorated due to the tectonic shifts in media production, distribution, access and consumption caused by digital technologies in general, and the Internet in particular. The gist of the debates has however curiously remained almost the same and is still focused on a set of economic arguments that call for state intervention in public media, and not unimportantly, on the various political interpretations of these economic arguments. In Europe, the debate has another essential core too, as Public Service Broadcasting (PSB) has been traditionally entrusted to serve some higher goals intrinsically related to key democratic and cultural processes. Accordingly, PSB in Western Europe has developed as the core media institution at the national level and has become deeply embedded in many facets of the nation’s economic, political, social and cultural life. Against the backdrop of PSB’s history, its vital tasks in society, as well as the dramatic changes brought about by the digitally networked environment, the question on the future of PSB and its transition into Public Service Media (PSM) is very interesting, to say the least, and highly challenging at the same time. The book by Karen Donders, Public Service Media and Policy in Europe (Palgrave, 2012), makes an essential contribution to these complex debates, and more importantly, adds some new value to an otherwise saturated discourse.

Men Between: The Role of Zambian Broadcasters in Decolonisation

This article traces the history of a group of Zambian broadcasters who established the first radio station in the country and made their mark on broadcasting for years to come. It describes their contribution to modern Zambian culture and to nationalist mobilisation. African broadcasters developed formats, ways of presenting and choices of music that appealed to Zambian listeners and established new, authentically local styles. While radio quickly established itself as an integral part of everyday life and culture in the colony, its effect was highly ambivalent. Broadcasters at the same time undermined and enforced the colonial project of using the medium as a transmitter of modernisation ideology. The article explores Thomas Turino’s characterisation of this team as ‘cosmopolitans’ and shows how they were influenced by BBC ideas of journalism and modernisation ideology. To do so, it analyses the relationships African broadcasters had with Europeans in senior positions and with colonial and postcolonial governments. This shared value system brought these Zambian broadcasters into conflict with the post-independence government and its plans to bureaucratise radio, despite their nationalist commitment and strong support for the United National Independence Party (UNIP) before independence.

Language ideologies: the formation and legitimisation of New Zealand English

New Zealand English first emerged at the beginning of the 19th century as a result of the dialect contact of British (51%), Scottish (27.3%) and Irish (22%) migrants (Hay and Gordon 2008:6). This variety has subsequently developed into an autonomous and legitimised national variety and enjoys a distinct socio-political status, recognition and codification. In fact, a number of dictionaries of New Zealand English have been published1 and the variety is routinely used as the official medium on TV, radio and other media. This however, has not always been the case, as for long only British standard norms were deemed suitable for media broadcasting. While there is some work already on lay commentary about New Zealand English (see for example Gordon 1983, 1994; Hundt 1998), there is much more to be done especially concerning more recent periods of the history of this variety and the ideologies underlying its development and legitimisation. Consequently, the current project aims at investigating the metalinguistic discourses during the period of transition from a British norm to a New Zealand norm in the media context, this will be done by focusing on debates about language in light of the advent of radio and television. The main purpose of this investigation is thus to examine the (language) ideologies that have shaped and underlain these discourses (e.g. discussions about the appropriateness of New Zealand English vis à vis external, British models of language) and their related practices in these media (e.g. broadcasting norms). The sociolinguistic and pragmatic effects of these ideologies will also be taken into account. Furthermore, a comparison will be carried out, at a later stage in the project, between New Zealand English and a more problematic and less legitimised variety: Estuary English. Despite plenty of evidence of media and other public discourses on Estuary English, in fact, there has been very little metalinguistic analysis of this evidence, nor examinations of the underlying ideologies in these discourses. The comparison will seek to discover whether similar themes emerge in the ideologies played out in publish discourses about these varieties, themes which serve to legitimise one variety, whilst denying such legitimacy to the other.

Estimating Perceived Video Quality from Objective Parameters in Video over IP Services

In Video over IP services, perceived video quality heavily depends on parameters such as video coding and network Quality of Service. This paper proposes a model for the estimation of perceived video quality in video streaming and broadcasting services that combines the aforementioned parameters with other that depend mainly on the information contents of the video sequences. These fitting parameters are derived from the Spatial and Temporal Information contents of the sequences. This model does not require reference to the original video sequence so it can be used for online, real-time monitoring of perceived video quality in Video over IP services. Furthermore, this paper proposes a measurement workbench designed to acquire both training data for model fitting and test data for model validation. Preliminary results show good correlation between measured and predicted values.

Subjective Evaluation of Transmission Errors in IPTV and 3DTV

The increase of multimedia services delivered over packet-based networks has entailed greater quality expectations of the end-users. This has led to an intensive research on techniques for evaluating the quality of experience perceived by the viewers of audiovisual content, considering the different degradations that it could suffer along the broadcasting system. In this paper, a comprehensive study of the impact of transmission errors affecting video and audio in IPTV is presented. With this aim, subjective assessment tests were carried out proposing a novel methodology trying to keep as close as possible home environment viewing conditions. Also 3DTV content in side-by-side format has been used in the experiments to compare the impact of the degradations. The results provide a better understanding of the effects of transmission errors, and show that the QoE related to the first approach of 3DTV is acceptable, but the visual discomfort that it causes should be reduced.

Making Transport Safer: V2V-Based Automated Emergency Braking System

An important goal in the field of intelligent transportation systems (ITS) is to provide driving aids aimed at preventing accidents and reducing the number of traffic victims. The commonest traffic accidents in urban areas are due to sudden braking that demands a very fast response on the part of drivers. Attempts to solve this problem have motivated many ITS advances including the detection of the intention of surrounding cars using lasers, radars or cameras. However, this might not be enough to increase safety when there is a danger of collision. Vehicle to vehicle communications are needed to ensure that the other intentions of cars are also available. The article describes the development of a controller to perform an emergency stop via an electro-hydraulic braking system employed on dry asphalt. An original V2V communication scheme based on WiFi cards has been used for broadcasting positioning information to other vehicles. The reliability of the scheme has been theoretically analyzed to estimate its performance when the number of vehicles involved is much higher. This controller has been incorporated into the AUTOPIA program control for automatic cars. The system has been implemented in Citroën C3 Pluriel, and various tests were performed to evaluate its operation.

Integración Wi-Fi en un proyecto ICT

La instalación de Infraestructuras Comunes de Telecomunicación (IICCTT) en el interior de las edificaciones para el acceso a los servicios de telecomunicación facilitó la incorporación a las viviendas de las nuevas tecnologías de forma económica y transparente para los usuarios. Actualmente, todos los edificios de nueva construcción deben presentar un proyecto ICT firmado por un Ingeniero Técnico de Telecomunicación de la especialidad correspondiente o un Ingeniero de Telecomunicación. La legislación que las regula afecta a todo tipo de viviendas con independencia del poder adquisitivo del comprador, y contribuye de manera decisiva a que disminuyan a corto y medio plazo las desigualdades sociales en lo relativo al acceso a servicios de telecomunicación tales como telefonía, Internet, telecomunicación por cable, radiodifusión sonora y televisión analógica, digital, terrenal o por satélite, etc.. Desde 1997, el Colegio Oficial de Ingenieros de Telecomunicación junto con otras organizaciones públicas y privadas ha participado en la elaboración de la normativa aplicable a las Infraestructuras Comunes de Telecomunicación, dando lugar al actual decreto, el Real Decreto 346/2011, de 11 de Marzo. El propósito general de este proyecto es diseñar una red Wi-Fi a partir de las canalizaciones e instalaciones del proyecto ICT de un conjunto de viviendas unifamiliares, para que todas ellas dispongan de conexión a internet de forma inalámbrica. Para llevar a cabo este diseño, se ha realizado un estudio de las características del estándar IEEE 802.11, conocido como Wi-Fi, analizando las posibilidades de comunicación inalámbrica que ofrece, así como las limitaciones que presenta en la actualidad. Se ha analizado el proyecto ICT del conjunto de viviendas, estudiando la viabilidad de utilizar sus instalaciones para implementar la red Wi-Fi, añadiendo tanto las canalizaciones como los dispositivos comerciales necesarios para llevar a cabo dicha implementación. Además, se ha estudiado la posibilidad de integrar la red Wi-Fi utilizando el cableado de televisión de la propia ICT. Por último, se ha estudiado la gran importancia que al Hogar Digital se da en el Real Decreto 346/2011, de 11 de marzo, por el que se aprueba el Reglamento regulador de las Infraestructuras Comunes de Telecomunicaciones para el acceso a los servicios de telecomunicación en el interior de las edificaciones, presentando los aspectos fundamentales que se persiguen con la domotización de la vivienda como mejora de vida de sus habitantes. Abstract The installation of Telecommunications Common Infrastructures (TCIs, in Spanish Infraestructuras Comunes de Telecomunicación –IICCTT-) in the buildings, in order to gain access to telecommunications services, facilitated the incorporation into the houses of new technologies in an economical and transparent way for users. Nowadays, every new construction building must have a TCI project signed by a Telecommunications Engineer or a Technical Telecommunications Engineer with the appropriate specialization. The legislation that regulates TCIs affects every kind of houses, independently of the buyer´s purchasing power, and contributes decisively to decrease in short and medium terms the social inequalities concerning the access to the telecommunication services, such as telephony, Internet, wired telecommunications, audible broadcasting and digital, analogical, land, satellite television, etc.. Since 1997, the Telecommunications Engineer Official College, together with other public and private organizations, has been elaborating the regulations for the TCIs, giving rise to the current decree, the Royal Decree 346/2011, of 11th of March. The general purpose of this project is to design a Wi-Fi network based on the canalizations and installations of the TCI project of a housing development, in such a way that every house is provided with a wireless connection to the Internet. In order to carry out this design, the characteristics of the standard IEEE 802.11, known as Wi-Fi, have been studied, analyzing the wireless-communication possibilities that it offers, as well as the constraints that it presents currently. The TCI project has been analyzed, studying the feasibility of using its installations to implement the Wi-Fi network, adding the canalizations and commercial devices required to execute the aforementioned implementation. Besides, the possibility of integrating the Wi-Fi network using the television wires of the TCI project has been investigated. Finally, it has been studied the great importance that has been given to Digital Home in the Royal Decree 346/2011, of 11th of March, that approves the regulatory Regulations of Telecommunications Common Infrastructures for the access to telecommunications services inside the buildings, presenting the essential aspects that are pursued with the house domotization as a way to improve the quality of life of its inhabitants.

Educational innovation applied in the UNESCO chair of mining and industrial heritage

The “Innovatio Educativa Tertio Millennio” group has been 10 years developing educational innovation techniques, actually has reached the level of teaching on the technical teachers has developed, and share them with other groups, that can implement them in their teaching activities. UNESCO Chair of Mining and Industrial Heritage has been years working on heritage, and on the one hand teaching in conservation and maintenance of heritage, and on the other doing raise awareness of the meaning of heritage, the social value and as must be managed effectively. Recently these two groups work together, thus is spreading in a much more effective manner the concepts of heritage, its meaning, its value, and how to manage it and provide effective protection. On one hand being a work of dissemination based on internet and on radio broadcasting, and on the other one of teaching based on educational innovation, and courses, conferences, and face-to-face seminars or distance platforms.

Remote Delivery of Video Services over video links

The spreading of new systems of broadcasting and distribution of multimedia content has had as a consequence a larger need for aggregation of data and metadata to traditionally based contents of video and audio supply. Broadcasting chains of this type of channels have become overwhelmed by the quantity of resources, infrastructures and development needed for these channels to provide information. In order to avoid this kind of shortcomings, several recommendations and standards have been created to exchange metadata between production and distribution of taped programs. The problem lies in live programs, producers sometimes offer data to channels but most often, channels are not able to face required developments. The key to this problem is cost reduction. In this work, a study is conducted on added services which producers may provide to the media about content; a system is found by which additional communication expenses are not made and a model of information transfer is offered which allows low cost developments to supply new media platforms.

Gestión de pruebas para equipos de vídeo

Desde hace ya muchos años, uno de los servicios de telecomunicaciones más demandado por los españoles ha sido la televisión de pago, complementando y ampliando la oferta de contenidos audiovisuales que habitualmente son ofrecidos de manera gratuita por la televisión analógica y recientemente por la televisión digital terrestre o TDT. Estos servicios de video, han sido tradicionalmente ofrecidos por operadores satélites, operadores de cable u otros operadores de telecomunicaciones con los que a través de una conexión de datos (ADSL, VDSL o fibra óptica), ofrecían sus contenidos a través de IP. La propia evolución y mejora de la tecnología utilizada para la emisión de contenidos sobre IP, ha permitido que a día de hoy, la televisión se conciba como un servicio Over The Top (OTT) ajeno al medio de transmisión, permitiendo a cualquier agente, distribuir sus contenidos audiovisuales de manera sencilla y a todos sus clientes en todas las partes del mundo; siendo solamente necesario disponer de una conexión a internet. De esta manera, el proyecto desarrollado va a girar en torno a la herramienta StormTest de la empresa S3Group, comprada por CENTUM Solutions (empresa especializada en ofrecer servicio de ingeniería para sistema de comunicaciones, control e inteligencia de señal) con el objetivo de satisfacer las necesidades de sus clientes y con la que en definitiva se ha contado para la realización de este proyecto. El principal objetivo de este proyecto es la definición e implementación de un banco de pruebas que permita optimizar los procesos de validación técnica, mejorando los tiempos de ejecución y concentrando la actividad de los ingenieros en tareas de mayor valor. Para la realización de este proyecto, se han fijado diversos objetivos necesarios para el desarrollo de este tipo de actividades. Los principales son los siguientes:  Análisis de la problemática actual: donde en los procesos de aceptación técnica se dedica muchas horas de trabajo para la realización de pruebas repetitivas y de poco valor las cuales se pueden automatizar por herramientas existentes en el mercado.  Búsqueda y selección de una herramienta que satisfaga las necesidades de pruebas.  Instalación en los laboratorios.  Configuración y adaptación de la herramienta a las necesidades y proyectos específicos. Con todo ello, este proyecto cubrirá los siguientes logros:  Reducir los tiempos de ejecución de las campañas de pruebas, gracias a la automatización de gran parte ellas.  Realizar medidas de calidad subjetiva y objetiva complejas, imposibles de ejecutar a través de las personas. Mejorar y automatizar los sistemas de reporte de resultados. Abstract: Many years ago, one of the telecommunications services most demanded in Spain has been pay television, complementing and extending the offer of audiovisual content which are usually offered for free by analog tv and recently by digital terrestrial televisión or TDT. These video services, have been traditionally offered by satellite operators, cable operators or other telecommunications operators that through a data connection (ADSL,VDSL or fiber optic), offered its content over IP. The evolution and improvement of the technology used for broadcasting over IP, has allowed that to date, television is conceived as a service Over The Top (OTT), not dependent on the transmission medium, allowing any agent to distribute audiovisual content in a very simple way and to all its customers in all parts of the world; being only necessary to have an decent internet connection. In this way, the project will have relation with S3Group’s StormTest tool, bought by CENTUM Solutions (company specialized in engineering services for communications, control and signal intelligence system) with the aim of satisfying the needs of its customers and which ultimately has counted for the realization of this project. The main objective of this project is the definition and implementation of a test bench that allows to optimize the processes of technical validation, improving execution times and concentrating the activities of engineers on higher value tasks. For the realization of this project, it has been defined several objectives necessary for the development of this type of activity. The most important tones are listed below:  Analysis of the current situation: where in technical acceptance processes it is dedicated many hours of work for the completion of repetitive testing and without value which can be automated by tools available on the market  Search and selection of a tool that meets the needs of testing.  Installation on the laboratories.  Configuration and customization of the tool to specific projects. With all this, this project will cover the following achievements: Reduce the execution time of the testing campaigns, thanks to the automation of many of them.  Measurements of subjective and objective quality tests, impossible to run with engineers (due to subjective perception). Improve and automate reporting of results systems

Desarrollo de la radio en el marco de las rivalidades político-militares de principios del siglo XX

A lo largo de este proyecto, se analizarán los comienzos de la radio en las primeras décadas del siglo XX, teniendo como objetivo describir el desarrollo científico-tecnológico y las rivalidades político-militares de las potencias europeas de Reino Unido y Alemania. En primer lugar se verán los precursores de la radio que existían anteriormente al surgimiento de la radiotelegrafía como la telegrafía óptica, la telegrafía eléctrica o el teléfono. Al igual que los primeros investigadores, como James Clerk Maxwell o Heinrich Rudolf Hertz, gracias a los cuales el origen de la radio fue posible. También se analizará el contexto histórico-político de Reino Unido y Alemania donde se muestran las características de las dos grandes potencias del momento, el Imperio Británico y el Imperio Alemán. Además, la cada vez mayor importancia de la telegrafía sin hilos, hará necesaria una organización internacional, dando lugar a las Conferencias Internacionales de Radiotelegrafía y que enfrentarán a estas dos potencias por defender sus intereses. Guillermo Marconi, por parte de Reino Unido, y Telefunken, por parte de Alemania, serán las principales marcas comerciales de radiotelegrafía, no solo en sus respectivos países, sino también en el resto del mundo. Entre ambas compañías se verán las rivalidades por la incesante lucha de patentes, el desarrollo tecnológico y el control de los mercados. También se tratará el enfrentamiento directo que se produjo en la Primera Guerra Mundial, donde la radio jugaría un papel fundamental. Por último, se analizarán los comienzos de la radiodifusión en la segunda década del siglo XX, donde la radio ya estaba consolidada como uno de los medios de comunicación más importante de la época, capaz de llegar a todos los rincones del planeta y perfectamente integrada en la sociedad del momento. ABSTRACT. Throughout this project, it will be analyzed the beginning of the radio in the first decades of the XX century, having as goal to describe the scientific-technological development and the political-militaries opponents of the European’s countries, United kingdom and Germany. Firstly, it will be shown the radio’s precursors before the origin of the wireless telegraphy, like: optical telegraphy, electric telegraphy or telephone. Moreover, it will show the first researchers like: Clerk Maxwell or Heinrich Hertz, thanks to them, the origin of the radio was possible. In addition, it will analyze the historical-political context of United Kingdom and Germany, where it is shown the main features of the Britain Empire and the German Empire. Moreover, the importance of the telegraphy without wire will make necessary and international organization, resulting the International Conferences of Wireless Telegraphy and it will put together these main countries in order to protect their interests. Guglielmo Marconi, by United Kingdom, and Telefunken, by Germany, they will be the main commercials brand of the wireless telegraphy, not only in their countries, but also in all over the world. Between both companies will be seen the main competitions for their patens, the technology development and the market’s control. Moreover, it will be dealt the direct conflict in the First World of War, where the radio has a fundamental role. Finally, it will be analyze the beginning of the wireless broadcasting in the second decade of the XX century, where the radio was established as one of the most important media of the age, able to arrive at every places of the world and it was perfectly integrated in the society of that moment.

Diseño y test VHDL de un cambiador de formato para ver TV3D en un televisor convencional

La difusión de TV3D actual utiliza formatos como el Side-by-Side o Top-and-Bottom, en los que cada par de imágenes, correspondiente a las vistas de los ojos derecho e izquierdo, se encapsula con la mitad de la resolución espacial en una sola imagen. Estas imágenes se muestran de manera casi simultánea de forma que el ojo humano compone una imagen con profundidad que se asemeja a la visión binocular natural. Desde hace un par de años las principales plataformas de televisión han empezado a crear canales con contenido 3D. La televisión 3D (TV3D) se ha introducido en los hogares gracias a los televisores estereoscópicos. Estos televisores, que son compatibles con los formatos antes mencionados, extraen de cada imagen sus dos vistas, recuperan la resolución original y presentan cada vista alternativamente en la pantalla, generando al mismo tiempo una señal de sincronismo para las gafas activas, creando de esta forma la sensación tridimensional de las imágenes. En este PFC se pretende realizar el diseño VHDL de un cambiador de formato que genere en tiempo real la secuencia de imágenes correspondiente a los ojos derecho e izquierdo, con resolución completa, a partir de una secuencia codificada en formato tipo Top-and-Bottom y el banco de test para su prueba. Este circuito se implementará como un periférico del procesador NIOS II de Altera. El diseño podría utilizarse como parte de un sistema que permita la visualización de las actuales emisiones de televisión 3D en un televisor convencional. La tecnología de referencia que se utilizará serán las FPGAs, más concretamente la tarjeta Cyclone III FPGA Starter Kit (EP3C25 FPGA) de Altera, junto a una tarjeta de ampliación de Microtronix con entrada y salida HDMI para video y audio. Además se pretende crear la documentación necesaria para el desarrollo de futuros trabajos relacionados con la televisión 3D. ABSTRACT Current TV3D broadcasting uses formats as Side-by-Side or Top-and-Bottom, where every single pair of images, corresponding to left and right eyes views, are encapsulated with half spatial resolution in one single image. These images are almost simultaneously displayed so that the human eye forms an image with depth resembling naturally binocular vision. From a couple of years the major TV platforms have begun to create 3D content channels. 3D Television (3DTV) has been introduced in homes through stereoscopic televisions. These televisions, which are compatible with the above formats, each image is extracted from the two views, and recover the original resolution and displays alternately each view in screen, while generating a synchronization signal for active glasses, thereby creating the three-dimensional sensation of the images. The main objective in this PFC is to make the design of an exchanger VHDL format in real time to generate the image sequence corresponding to the right and left eyes, with full resolution from an encoded sequence type format Top-and-Bottom and test bench for testing. This circuit is implemented as a Altera NIOS II processor peripheral.The design could be used as part of a system enabling the display of current television broadcasts 3D on a conventional television. The reference technology that will be use are FPGAs, more specifically Cyclone III FPGA Starter Card Kit (EP3C25 FPGA) Altera, along with an expansion card Microtronix with HDMI input and output video and audio. It also aims to create documentation for the development of future works related to 3D TV.
