1. COMPOSER: AN AUTHORING TOOL OF NCL DOCUMENTS FOR INTERACTIVE DIGITAL TV / COMPOSER: UM AMBIENTE DE AUTORIA DE DOCUMENTOS NCL PARA TV DIGITAL INTERATIVA
With the advent of adoption of an interactive digital TV standard by the Brazilian government, the interest for the analysis of possible alternatives in several areas that compose a digital TV system has increased. In the case of Brazil, NCL is the declarative language adopted for modeling interactive applications in the Brazilian Terrestrial Digital TV Syst

2. ON-THE-FLY TIMESCALE FOR COMPRESSED AUDIO STREAMS / AJUSTE ELÁSTICO EM TEMPO DE EXIBIÇÃO PARA FLUXOS DE ÁUDIO COMPRIMIDO
Timescale is a technique used to modify media-object playing duration. This work proposes timescale algorithms, to be performed on-the- fly, for compressed audio streams. The focus is situations where there is no user interference as, for example, the temporal consistency maintenance of a hypermedia document. The algorithms are proposed, developed and integr

3. A DECLARATIVE MIDDLEWARE TO INTERACTIVE TV SYSTEMS / UM MIDDLEWARE DECLARATIVO PARA SISTEMAS DE TV DIGITAL INTERATIVA
The evolution of digital modulation techniques and the efficient schemes for digital transmissions have allowed the advent of the digital TV. Conceiving low cost receivers is one of the main challenges to broaden digital TV use, mainly in non-developed countries. As a consequence, low cost requirements should not burden receiver resources that should try to

4. INTEGRAÇÃO E INTEROPERABILIDADE DE DOCUMENTOS MPEG-4 E NCL / INTEGRATION AND INTEROPERABILITY OF MPEG-4 AND NCL DOCUMENTS
The MPEG-4 standard object-oriented approach, employed to the encoding of audiovisual content, is similar to those used on many models and languages for multimedia/hypermedia document specification. Among those languages, the NCL (Nested Context Language), used in the HyperProp system, introduces a series of new concepts that can be integrated to the standar

5. FORMATAÇÃO E CONTROLE DE APRESENTAÇÕES HIPERMÍDIA COM MECANISMOS DE ADAPTAÇÃO TEMPORAL / FORMATTING AND CONTROLLING HYPERMEDIA PRESENTATIONS WITH TEMPORAL ADAPTATION MECHANISMS
A construção de sistemas hipermídia/multimídia requer a implementação de um elemento responsável por receber a especificação de um hiperdocumento (sua estrutura, seus relacionamentos e a descrição da forma de exibição desejada) e concretizá-la na apresentação propriamente dita, sendo esse módulo de controle de execução comumente denominado
