ABSTRACT:
A method of using finite state machines (FSMs) is disclosed for controlling multiple processes in response to input signals. In an exemplary embodiment, such processes comprise facilities for providing interactive television services and multimedia signals for such services. The FSMs are arranged in a tree-like structure and communicate with each other by event messages of various types. Each FSM has multiple states and permitted state transitions. Transitions occur in response to event messages and/or input signals, and a transition can cause one or more event messages associated with such transition to be sent. At least one terminal FSM is associated with each of the multiple processes and controls that process. Status changes in each process can also cause state transitions in the FSMs. The FSMs are resident in the various processors controlling the multiple processes, which can be situated at different locations.
