Avec les progrès technologiques en matière de débits disponibles et la diversification des média disponibles, l'enjeu est maintenant de diffuser aux utilisateurs des médias de qualité dans une présentation cohérente, attractive et interactive, qu'elle soit destinée au monde de la télévision numérique, de l'Internet ou de la téléphonie mobile. Les descriptions de scènes multimédia tentent de répondre à ce pari. Le pari consiste en effet à développer des technologies permettant la diffusion et la présentation de contenu multimédia riche, animé, interactif dans des environnements aux contraintes multiples. Il faut des technologies suffisamment simples pour être intégrées dans des terminaux à faible coût de revient, mais également suffisamment attractives pour attirer de nouveaux consommateurs. Ensuite, même si les débits augmentent et les techniques de compression s'améliorent, la plus grande partie des "tuyaux" est encore occupée par les média traditionnels (audio, vidéo). Il faut donc que ces nouvelles technologies n'occupent pas trop de bande passante. Enfin, pour qu'elles mènent à de nouveaux usages, il faut que les créateurs de contenu se les approprient et pour cela, il faut que les présentations multimédia soient faciles à créer, quel que soit le scénario d'utilisation. Cette thèse a pour objectif dans un premier temps de mener une réflexion sur les différentes représentations de scènes multimédias existantes et d'en proposer une synthèse. Cette synthèse propose une vue générale sur les langages, les formats de représentation des descriptions de scènes ainsi que sur les techniques de codage et les traitements appliqués aux scènes multimédia. Elle présente, en particulier, les problématiques liées à l'animation, la compression, l'interactivité, la diffusion et finalement à la présentation. Dans un second temps, elle propose des améliorations aux solutions existantes. Ces propositions sont doubles. Tout d'abord, cette thèse propose d'un ensemble de méthodes pour permettre la représentation efficace de scènes multimédia fortement animées, notamment pour les formats de représentations MPEG-4 BIFS, W3C SVG et MPEG-4 LASeR, et avec la prise en compte des contraintes de la diffusion sur téléphone mobile. Ensuite, cette thèse propose une architecture et une implémentation innovante d'un lecteur de scènes permettant la lecture de contenus multimédia sur terminaux contraints grâce au respect d'un compromis entre consommation mémoire et rapidité d'exécution. Cette thèse se conclut, après avoir rappelé les contraintes du monde mobile, par une synthèse des choix technologiques à faire, dans la vaste bibliothèque d'outils disponibles dans le domaine des descriptions de scènes, pour concevoir un service multimédia pour mobiles.

<p>In the post-genomics era, the sheer volume of data is overwhelming without appropriate tools for data integration and analysis. Studying genomic sequences in the context of other related genomic sequences, i.e. comparative genomics, is a powerful technique enabling the identification of functionally interesting sequence regions based on the principal that similar sequences tend to be either homologous or provide similar functionality.</p> <p>Costs associated with full genome sequencing make it infeasible to sequence every genome of interest. Consequently, simple, smaller genomes are used as model organisms for more complex organisms, for instance, Mouse/Human. An annotated model organism provides a source of annotation for transcribed sequences and other gene regions of the more complex organism based on sequence homology. For example, the gene annotations from the model organism aid interpretation of expression studies in more complex organisms.</p> <p>To assist with comparative genomics research in the Arabidopsis/Brassica (Thale-cress/Canola) model-crop pair, a web-based, graphical genome browser (BioViz) was developed to display short Brassica genomic sequences in the context of the Arabidopsis model organism genome. This involved the development of graphical representations to integrate data from multiple sources and tools, and a novel user interface to provide the user with a more interactive web-based browsing experience. While BioViz was developed for the Arabidopsis/Brassica comparative genomics context, it could be applied to comparative browsing relative to other reference genomes.</p> <p>BioViz proved to be an valuable research support tool for Brassica / Arabidopsis comparative genomics. It provided convenient access to the underlying Arabidopsis annotation, allowed the user to view specific EST sequences in the context of the Arabidopsis genome and other related EST sequences. In addition, the limits to which the project pushed the SVG specification proved influential in the SVG community. The work done for BioViz inspired the definition of an opensource project to define standards for SVG based web applications and a standard framework for SVG based widget sets.</p>

Paralelamente, o impacto da informática sobre a cartografia causou surgimento de novas técnicas e recursos que potencializaram seu uso. Até recentemente os mapas digitais encontrados na Internet eram apresentados como imagens matriciais, com pouca ou nenhuma interatividade com o usuário, limitando-se a exibir o mapa na tela do computador. O surgimento da linguagem XML (extensible Markup Language) trouxe novas possibilidades para publicação de mapas na Internet, em função de sua capacidade de manipular dados gráficos. Este trabalho procura explorar o potencial da linguagem SVG, que é baseada em XML, para publicação de mapas no ambiente da Internet, apresentando ferramentas como um alternativa para qualquer instituição que necessite divulgar informações espaciais de maneira simplificada, sem necessariamente usar banco de dados ou servidor de mapas. Primeiramente faz-se uma abordagem teórica sobre disseminação dos dados espaciais na Internet e as linguagens de marcação envolvidas, mostrando suas principais características. Depois o trabalho aborda aspectos da seleção de mapas para publicação, a sua transformação para o formato SVG, implementação de JavaScripts nos arquivos para proporcionar interatividade e finalmente apresenta dois protótipos para montagem de uma página contendo o mapa e ferramentas para interação. Os protótipos foram projetados para casos onde os atributos e complexidade dos mapas é relativamente reduzida, dispensando a necessidade de um servidor de mapas. A linguagem SVG mostra-se promissora para apresentação de mapas na Internet devido a sua flexibilidade e grande capacidade de interação com o usuário, além de mostrar uma clara tendência de se tornar uma linguagem padrão nos próximos anos. O maior problema encontrado reside na necessidade de instalação de "plug-in" no navegador de Internet para visualização dos gráficos nesse formato.

It is based on the Scalable Vector Graphics (SVG) standard for Web development of graphics. The project uses the concept of remate and real-time mar creation by database access through instructions executed by browsers on the Internet. As a way of proving the system effectiveness, we present two study cases;.the first on a region named Maracaja? Coral Reefs, located in Rio Grande do Norte coast, and the second in the Switzerland Northeast in which we intended to promote the substitution of MapServer by the system proposed here. We also show some results that demonstrate the larger geographical data capability achieved by the use of the standardized codes and open source tools, such as Extensible Markup Language (XML), Document Object Model (DOM), script languages ECMAScript/ JavaScript, Hypertext Preprocessor (PHP) and PostgreSQL and its extension, PostGIS / Neste trabalho, propomos um Sistema de Informa??es Geogr?ficas voltado para a Web que sirva de ferramenta base para o tratamento e estudo de quest?es relacionadas com o meio-ambiente e gest?o de cidades, baseado no uso do padr?o Scalable Vector Graphics (SVG) para desenvolvimento gr?fico na Web. O projeto utiliza o conceito de cria??o remota e em tempo real de mapas atrav?s do acesso ao banco de dados pelas instru??es executadas pelos browsers na rede mundial de computadores. Inicialmente a ?nfase ser? direcionada aos parrachos de Maracaja?, localizado no litoral do Rio Grande do Norte, e logo ap?s a um estudo realizado na regi?o Nordeste da Su??a em que se prop?e a substitui??o do MapServer pelo sistema a ser discutido. Dessa forma, ser?o debatidos resultados que demonstram a maior capacidade de representa??o de dados geogr?ficos mediante a utiliza??o de c?digos padronizados e fontes abertas, tais como Extensible Markup Language (XML), Document Object Model (DOM), linguagens de script ECMAScript/ JavaScript e Hypertext Preprocessor (PHP), bem como o Sistema de Gerenciamento de Banco de Dados PostgreSQL e sua extens?o, o PostGIS

ScoreSVG implements a three-tiered software architecture that generates musical scores in scalable vector graphics (SVG), something no other known music editor has done. SVG is non-proprietary XML-based format that renders graphical content into a web browser equipped with a SVG plugin. Scores in SVG can be scripted to produce interactive music theory examples, or make other graphical score changes impossible in any other format. Large music score editors such as Finale and Sibelius output to proprietary file formats, or Postscript (.ps) files that are not interchangeable or modifiable once created. Open source efforts such as LilyPond or Guido require the user to learn a new text-based music format to get a PostScript music score. ScoreSVG converts the data from a user-friendly visual front end to GuidoXML, capturing the semantic meaning of the score, and then outputs the result in SVG using an XSL stylesheet and the Saxon 8.4 XSLT processor.

A set top box is an embedded device, much like a computer with limited capabilities. Its main purpose is to decode a video signal and output it to a TV. The set top box market is constantly growing and to be competitive in it, a set top box has to be able to do more than only TV. One way to make an attractive product is to give it an appealing user interface. This thesis is a part of a larger work at the company to find new ways to create graphical user interfaces. Its goal is to investigate what SVG implementations that exits, which one that is most suitable for an integration attempt and then perform the integration. Several SVG engines were investigated and one provided by the company was selected for integration. Three ways to integrate the SVG engine were identified. One of these alternatives was to extend the callback interface be- tween the engine and the underlying platform. Because of the good fit with the current architecture this alternative was chosen and implemented. As a part of this investigation a demo application suite of SVG content was also constructed. This investigation resulted in a working integration of the chosen SVG engine on the platform. It has also showed that SVG is a suitable language to build graphical user interfaces on set top boxes.
