Interactive digital television systems should adopt concepts of adaptation in order to make possible the development of configurable and extensible applications. On the other hand, software component technologies allow software designers to design, develop, maintain and evolve software systems based upon the integration, substitution and adaptation of already available, reusable software artifacts. In previous papers we presented an adaptive middleware with this objective. The present paper extends this middleware to include a meta-component model to describe and to represent applications independently of technology aspects. The paper also describes the implementation of the model that has been used to build an example application.Plataformas para sistemas de televisão digital interativa devem adotar conceitos de adaptação, de forma a viabilizar o desenvolvimento de aplicações configur´veis e extensíveis. Por outro lado, a tecnologia de componentes permite que o projeto e o desenvolvimento dos sistemas de software possam ser realizados a partir da integração e adaptação de artefatos de software reutiliz´veis. Em artigos anteriores, apresentamos um projeto de um PLGGOHZDUH adaptativo para estes sistemas. O presente artigo estende esse PLGGOHZDUH propondo um modelo de metacomponentes que permite descrever e representar aplicações de forma independente de aspectos de tecnologia; o artigo descreve também a implementação do modelo, a qual est´ sendo usada para construir uma aplicação-exemplo.
