ABSTRACT
This paper aims at discussing the issues on the design and implementation of hypermedia formatters (commonly known as presentation engines) for interactive digital TV systems. The paper describes how these issues have been handled in the development project of the Maestro presentation engine. Maestro is the core of the declarative support offered by the middleware Ginga, whose architecture has been proposed as the reference model for the middleware of the Brazilian Digital TV System.Este artigo tem por objetivo discutir as peculiaridades no projeto e na implementação de formatadores hipermídia (comumente chamados de m´quinas de apresentação) para sistemas de TV digital interativa. O artigo descreve como tais questões foram tratadas no projeto de desenvolvimento da m´quina de apresentação Maestro. Maestro é o núcleo do suporte declarativo oferecido pelo middleware Ginga, cuja arquitetura é proposta como modelo de referência para o middleware do Sistema Brasileiro de TV Digital.

Automatic building of frameworks for processing XML documents
WebMedia '06: Proceedings of the 12th Brazilian Symposium on Multimedia and the webThis paper presents a two-layer model for the development of XML-based language compilers. In the first layer, a framework (generic compiler) is automatically generated from the XML Schema of a selected language (the input language). Besides defining ...
