Cultura da Wikipédia como Política de capacitação compartilhada em meio digital de socialização do conhecimento

Presents a developing laboratory within History of Culture, subject taught in the Library and Archive Studies at UNESP (Marilia). The project is based upon the foundations of research line Information and Technology: students from the second under graduation year participate in the improving of 27 entries in Portuguese language Wikipedia. The aim is to capacitate for scientific reading and writing in digital media, habilitate for the information identification and recuperation and for the interpretation and understanding of formal and contents aspects and its reorganization. It includes activities of search, selection, remix and republishing of texts, images, audio and videos in the convergence of diverse hypertext information sources, supported by tutors with strategic abilities in digital environments. In this sense it was adhered to the international Wikipedia Foundation University Campus Ambassadors project. It’s also aimed to induce sharing and collaboration behaviors with the purpose of creating necessary habits for the informational empowerment in Brazil. As methodology is to optimize the work of individuals already trained in wiki culture and to create in within the subject information sharing programs with a more specialized bias, giving greater credibility to the digital environment. The environment syntaxes helps in the learning of the complementary skills of reading and writing and offers itself as an open repository from which information can be reused. It is, thus, an empowerment strategy in the search of autonomy and self reliance considering intersemiotic knowledge in the edition, visualization and understanding of information in the social web. A second step of a verifying research on the environment’s credibility after the consolidation and dissemination of the entries improvement work is proposed.

Archives information publishing new design in post-custodial regime: the national archives experience digital vaults

The uses of Information and Communication Technologies (ICT) and Web environments for creation, treatment and availability of information have supported the emergence of new social-cultural patterns represented by convergences in textual, image and audio languages. This paper describes and analyzes the National Archives Experience Digital Vaults as a digital publishing web environment and as a cultural heritage. It is a complex system - synthesizer of information design options at information setting, provides new aesthetic aspects, but specially enlarges the cognition of the subjects who interact with the environment. It also enlarges the institutional spaces that guard the collective memory beyond its role of keeping the physical patrimony collected there. Digital Vaults lies as a mix of guide and interactive catalogue to be dealt in a ludic way. The publishing design of the information held on the Archives is meant to facilitate access to knowledge. The documents are organized in a dynamic and not chronological way. They are not divided in fonds or distinct categories, but in controlled interaction of documents previously indexed and linked by the software. The software creates information design and view of documental content that can be considered a new paradigm in Information Science and are part of post-custodial regime, independent from physical spaces and institutions. Information professionals must be prepared to understand and work with the paradigmatic changes described and represented by the new hybrid digital environments; hence the importance of this paper. Cyberspace interactivity between user and the content provided by the environment design provide cooperation, collaboration and sharing knowledge actions, all features of networks, transforming culture globally.

Televisão analógica e televisão digital: o futuro do telejornalismo

This study proposes to present the process of implementation of Digital TV, the available resources found in the Japanese standard employed in the country and the form in which news programs will adapt to the new technology. Following the presentation of the technological tools, the current state of Brazilian television is discussed, focusing on two nationally broadcast programs, Jornal da Band on Bandeirantes channel and Jornal da Record on Record channel. As a case study, three editions of each show are evaluated with an individual and comparative analysis. Following the analyses, perspectives on the future of television journalism in the digital TV age are given. Additionally, the possibilities for interaction between the TV viewer and the channel and the forms of interaction that may exist within particular programs are discussed, thus allowing for active participation from the part of the viewer. The newly developed functions of journalists in the digital age are also broken down in the research. In order to gain a full understanding of the phases of this process of technological convergence and how programs will adapt to these tools, interviews with professionals who work in the production of televised news programs are conducted in the study

Estrutura de conteúdos educativos para TV Digital: um modelo de referência

This paper proposes a model of educative content structuring for interactive digital television programs. Its intent was to provide references for collaborative production processes and content organization in learning networks associated with university and educative television broadcasting services. The model defines terms, actors, events, environments, as well as content categories, classes and attributes, indicating criteria for their synchronic or asynchronic association in a dynamic television schedule. The model is presented in both descriptive and visual formats, with the use of conceptual maps. The results indicate that interactive use of digital television in education requires systematic content models covering communitarian participation in both media production and distribution processes, in order to enhance learning instruments beyond vertical, hierarchical and centralized communication sustained by traditional broadcast channels.

Contribuições à análise de qualidade do jornalismo na comunicação pública digital

Scientific research has shown remarkable advances in the formulation of criteria for assessing the quality of journalism practiced in the commercial media and public broadcasting, comprising aspects such as management models, business principles, parameters to the assessment of results and exercise of social responsibility. However, there are fewer investigations on the practice of journalism in digital public communication formats explored by government web portals. The contribution of this paper lies in a proposal of elements for the construction of parameters for evaluating the quality of journalism in the digital public communication. The proposal is inspired by criteria for evaluating the quality of commercial media and public broadcasting and suggests means for its application in the journalism practiced in the context of government web portals.

Die Überarbeitung der Fernsehrichtlinie unter Berücksichtigung der EuGH-Entscheidungen zur bisherigen Fassung

Gegenstand der vorliegenden Arbeit ist die Überarbeitung der Richtlinie 89/552/EWG des Rates zur Koordinierung bestimmter Rechts- und Verwaltungsvorschriften der Mitgliedstaaten über die Ausübung der Fernsehtätigkeit, welche aus praktikablen Gründen meist als „(EG-)Fernsehrichtlinie“ bezeichnet wird. Sie bildet den Eckpfeiler der audiovisuellen Politik der EU. Seit Erlass der Fernsehrichtlinie im Jahre 1989 bewirkt der technologische Fortschritt jedoch zunehmend enorme Veränderungen nicht nur im Bereich des klassischen Fernsehens, sondern auch und vor allem im Bereich der neuen Medien. Ausgangspunkt hierfür ist die Verbesserung der Digitaltechnologie, die ihrerseits wiederum technische Konvergenzprozesse begünstigt. Diese Entwicklungen führen nicht nur zu einer Vervielfachung von Übertragungskapazitäten und –techniken, sondern ermöglichen neben neuen Formen audiovisueller Angebote auch die Entstehung neuer Dienste. Unsere Medienlandschaft steht vor „epochalen Umbrüchen“. Im Hinblick auf diese Vorgänge wird seit geraumer Zeit eine Überarbeitung der EG-Fernsehrichtlinie angestrebt, um dem technologischen Fortschritt auch „regulatorisch“ gerecht werden zu können. Diesem Überarbeitungsprozess möchte sich die vorliegende Arbeit widmen, indem sie die Fernsehrichtlinie in einem ersten Teil sowohl inhaltlich wie auch hinsichtlich ihrer Entstehungsgeschichte und der zu ihr ergangenen EuGH-Entscheidungen erläutert. Anschließend werden alle Überarbeitungsvorgänge der Fernsehrichtlinie seit 1997 dargestellt, um sodann die aktuellen Reformansätze analysieren und bewerten zu können. Aus zeitlichen Gründen (der neue Richtlinienvorschlag der Kommission vom 13. Dezember 2005 wurde ca. 2 Wochen vor dem Abgabetermin der Arbeit verabschiedet) sind die Ausführungen zum Entwurf der neuen „Richtlinie über audiovisuelle Mediendienste“ allerdings relativ knapp gehalten.

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.

Methods and Applications in Interactive Broadcasting

Interactive TV technology has been addressed in many previous works, but there is sparse research on the topic of interactive content broadcasting and how to support the production process. In this article, the interactive broadcasting process is broadly defined to include studio technology and digital TV applications at consumer set-top boxes. In particular, augmented reality studio technology employs smart-projectors as light sources and blends real scenes with interactive computer graphics that are controlled at end-user terminals. Moreover, TV producer-friendly multimedia authoring tools empower the development of novel TV formats. Finally, the support for user-contributed content raises the potential to revolutionize the hierarchical TV production process, by introducing the viewer as part of content delivery chain.

3-D Audio in Mobile Communication Devices: Methods for Mobile Head-Tracking

Future generations of mobile communication devices will serve more and more as multimedia platforms capable of reproducing high quality audio. In order to achieve a 3-D sound perception the reproduction quality of audio via headphones can be significantly increased by applying binaural technology. To be independent of individual head-related transfer functions (HRTFs) and to guarantee a good performance for all listeners, an adaptation of the synthesized sound field to the listener's head movements is required. In this article several methods of head-tracking for mobile communication devices are presented and compared. A system for testing the identified methods is set up and experiments are performed to evaluate the prosand cons of each method. The implementation of such a device in a 3-D audio system is described and applications making use of such a system are identified and discussed.

3-D Audio in Mobile Communication Devices: Effects of Self-Created and External Sounds on Presence in Auditory Virtual Environments

This article describes a series of experiments which were carried out to measure the sense of presence in auditory virtual environments. Within the study a comparison of self-created signals to signals created by the surrounding environment is drawn. Furthermore, it is investigated if the room characteristics of the simulated environment have consequences on the perception of presence during vocalization or when listening to speech. Finally the experiments give information about the influence of background signals on the sense of presence. In the experiments subjects rated the degree of perceived presence in an auditory virtual environment on a perceptual scale. It is described which parameters have the most influence on the perception of presence and which ones are of minor influence. The results show that on the one hand an external speaker has more influence on the sense of presence than an adequate presentation of one’s own voice. On the other hand both room reflections and adequately presented background signals significantly increase the perceived presence in the virtual environment.

Digital First Sale Doctrine Ante Portas – Exhaustion in the Online Environment

The purpose of the article is to provide first a doctrinal summary of the concept, rules and policy of exhaustion, first, on the international and EU level, and, later, under the law of the United States. Based upon this introduction, the paper turns to the analysis of the doctrine by the pioneer court decisions handed over in the UsedSoft, ReDigi, the German e-book/audio book cases, and the pending Tom Kabinet case from the Netherlands. Questions related to the licence versus sale dichotomy; the so-called umbrella solution; the “new copy theory”, migration of digital copies via the internet; the forward-and-delete technology; the issue of lex specialis and the theory of functional equivalence are covered later on. The author of the present article stresses that the answers given by the respective judges of the referred cases are not the final stop in the discussion. The UsedSoft preliminary ruling and the subsequent German domestic decisions highlight a special treatment for computer programs. On the other hand, the refusal of digital exhaustion in the ReDigi and the audio book/e-book cases might be in accordance with the present wording of copyright law; however, they do not necessarily reflect the proper trends of our ages. The paper takes the position that the need for digital exhaustion is constantly growing in society and amongst businesses. Indeed, there are reasonable arguments in favour of equalizing the resale of works sold in tangible and intangible format. Consequently, the paper urges the reconsideration of the norms on exhaustion on the international and EU level.
