The HAVi architecture defines the way devices are abstracted within the home network and establishes a framework for device control. It defines the ways that interoperability is assured, and it defines the ways that future devices and services can be integrated into the architecture. The HAVi network makes no restrictions, however, on what types of devices must be present in the home network. As a result, several configurations are possible—networks without FAV devices, networks with multiple FAV devices, networks with LAV and BAV devices only, etc. Depending on the types of devices on the home network, several configurations are possible. The following sections describe some of these possibilities.
