No. of bitstreams: 0 Previous issue date: 2007-02-02 / Multimedia systems must incorporate middleware concepts in order to abstract hardware and operational systems issues. Applications in those systems may be executed in different kinds of platforms, and their components need to communicate with each other. In this context, it is needed the definition of specific communication mechanisms for the transmission of information flow. This work presents a interconnection component model for distributed multimedia environments, and its implementation details. The model offers specific communication mechanisms for transmission of information flow between software components considering the Cosmos framework requirements in order to support component dynamic reconfiguration / Sistemas multim?dia devem incorporar conceitos de middleware de forma a abstrair especificidades de hardware e sistemas operacionais. Aplica??es nestes sistemas podem ser executadas em diferentes tipos de plataformas, e os componentes destes sistemas precisam interagir uns com os outros. Neste contexto, faz-se necess?rio a defini??o de mecanismos de comunica??o espec?ficos para a transmiss?o de fluxos de informa??o. Este trabalho apresenta um modelo para a interconex?o de componentes em ambientes multim?dia, e sua arquitetura de implementa??o. O modelo oferece mecanismos de comunica??o espec?ficos para a transmiss?o de fluxos de informa??o entre componentes de software atendendo aos requisitos do framework Cosmos de maneira a suportar a reconfigura??o din?mica de componentes
