Face paulista da TV digital: reflexão sobre a multiprogramação na TV cultura

The implantation procedure of the multiprogramming for TV Cultura, a station under the responsibility of the Fundação Padre Anchieta,from the regulation of digital television in Brazil, through the Sistema Brasileiro de Televisão Digital Terrestre (SBTVD-T), involves the creation and implantation of multiprogramming channels of the station, the Univesp TV and the Multicultura channels, which are functioning through means of a special authorization in scientific and experimental character. Analyzed from the Communication Politics Economy point of view, this research contributes to the reflexion about the multiprogramming which may create alternatives to new options in this country programming and content.

Portabilidade e Mobilidade na TV Digital: atrativos para a hospitalidade social

This paper ditach the portability and mobility of digital television as opportunities for promotion to the social hospitality. The digital technologies add news concepts to hospitality, converging to the redemption of the social being, integrating and strengthening social ties in the technological space. With the digital television, we may have new forms of sociability, because may be required and assisted in any place, as a result of their actions for portability and mobility, which allows the construction of social ties or an ample concept the hospitality social in public spaces.

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 Search: New Challenges in the Pervasive Digital Video Era

The explosion of multimedia digital content and the development of technologies that go beyond traditional broadcast and TV have rendered access to such content important for all end-users of these technologies. While originally developed for providing access to multimedia digital libraries, video search technologies assume now a more demanding role. In this paper, we attempt to shed light onto this new role of video search technologies, looking at the rapid developments in the related market, the lessons learned from state of art video search prototypes developed mainly in the digital libraries context and the new technological challenges that have risen. We focus on one of the latter, i.e., the development of cross-media decision mechanisms, drawing examples from REVEAL THIS, an FP6 project on the retrieval of video and language for the home user. We argue, that efficient video search holds a key to the usability of the new ”pervasive digital video” technologies and that it should involve cross-media decision mechanisms.

Interactive Ray Tracing for Virtual TV Studio Applications

In the last years, the well known ray tracing algorithm gained new popularity with the introduction of interactive ray tracing methods. The high modularity and the ability to produce highly realistic images make ray tracing an attractive alternative to raster graphics hardware. Interactive ray tracing also proved its potential in the field of Mixed Reality rendering and provides novel methods for seamless integration of real and virtual content. Actor insertion methods, a subdomain of Mixed Reality and closely related to virtual television studio techniques, can use ray tracing for achieving high output quality in conjunction with appropriate visual cues like shadows and reflections at interactive frame rates. In this paper, we show how interactive ray tracing techniques can provide new ways of implementing virtual studio applications.

MHP Oriented Interactive Augmented Reality System for Sports Broadcasting Environments

Television and movie images have been altered ever since it was technically possible. Nowadays embedding advertisements, or incorporating text and graphics in TV scenes, are common practice, but they can not be considered as integrated part of the scene. The introduction of new services for interactive augmented television is discussed in this paper. We analyse the main aspects related with the whole chain of augmented reality production. Interactivity is one of the most important added values of the digital television: This paper aims to break the model where all TV viewers receive the same final image. Thus, we introduce and discuss the new concept of interactive augmented television, i. e. real time composition of video and computer graphics - e.g. a real scene and freely selectable images or spatial rendered objects - edited and customized by the end user within the context of the user's set top box and TV receiver.

How to Improve the Production Process for interactive TV with semi-formal Methods

The central question for this paper is how to improve the production process by closing the gap between industrial designers and software engineers of television(TV)-based User Interfaces (UI) in an industrial environment. Software engineers are highly interested whether one UI design can be converted into several fully functional UIs for TV products with different screen properties. The aim of the software engineers is to apply automatic layout and scaling in order to speed up and improve the production process. However, the question is whether a UI design lends itself for such automatic layout and scaling. This is investigated by analysing a prototype UI design done by industrial designers. In a first requirements study, industrial designers had created meta-annotations on top of their UI design in order to disclose their design rationale for discussions with software engineers. In a second study, five (out of ten) industrial designers assessed the potential of four different meta-annotation approaches. The question was which annotation method industrial designers would prefer and whether it could satisfy the technical requirements of the software engineering process. One main result is that the industrial designers preferred the method they were already familiar with, which therefore seems to be the most effective one although the main objective of automatic layout and scaling could still not be achieved.

BrainMaps.org - Interactive High-Resolution Digital Brain Atlases and Virtual Microscopy

BrainMaps.org is an interactive high-resolution digital brain atlas and virtual microscope that is based on over 20 million megapixels of scanned images of serial sections of both primate and non-primate brains and that is integrated with a high-speed database for querying and retrieving data about brain structure and function over the internet. Complete brain datasets for various species, including Homo sapiens, Macaca mulatta, Chlorocebus aethiops, Felis catus, Mus musculus, Rattus norvegicus, and Tyto alba, are accessible online. The methods and tools we describe are useful for both research and teaching, and can be replicated by labs seeking to increase accessibility and sharing of neuroanatomical data. These tools offer the possibility of visualizing and exploring completely digitized sections of brains at a sub-neuronal level, and can facilitate large-scale connectional tracing, histochemical and stereological analyses.
