Currently, multimedia contents can be accessed at anytime and anywhere with a wide variety of devices, such as laptops, smartphones and tablets. In this paper, we present a service-based multimedia adaptation architecture where adaptation services can be available locally and remotely on multiple platforms. When conflicts are detected between some multimedia document properties and profile constraints, we propose a procedure that selects relevant adaptation services in order to compute an adapted document. This procedure may be executed locally or remotely, moreover for unsovled conflicts this one indicates which services may have to be installed.
