A meta-component model for dynamic adaptation support in a middleware system for interactive TV

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.
