In this paper we propose a meta-model for architectures with heterogeneous multimedia components. Currently, a generic solution does not exist to automatically deploy a distributed architecture based on multimedia components. The description of the incompatibilities between components is a need in such approaches. Indeed, software architectures validate the functional aspects, which are not sufficient to guarantee a realistic assembly. For instance, the problem of heterogeneity related to the exchanged data flows. In order to highlight these incompatibilities and to find solutions, a model-based approach called MMSA (Meta-model Multimedia Software Architecture) is proposed. It enables the description of the software architectures expressing a software system as a collection of components which handle various types and formats of data, and interacts between them via connectors including the adaptation connectors.
