Abstract A tuner component module within a home network based on the HAVi standard, i.e. a tuner FCM, according to the present invention includes the functionality to provide the capability of the tuner and/or to introduce the DVB/ DTV concepts of components and events to the HAVi network. In this context components could be audio, video or data streams associated with a service and events could e. g. be information for an electronic programming guide (EPG). The capability of a tuner in this context is all functions supported by the tuner. Therefore, a tuner FCM according to the present invention includes at least one of the following APIs and the corresponding (data/signal) structures neccessary to have a proper functionality: GetItemComponentList API(2), GetEventList API(3), SelectItemComponent API(4), GetCurrentItem-Component API(5)and GetCapability API(6).
