ABSTRACT:
A computer-based system and method for saving and restoring states in an interactive television system. The system presents interactive programs to a user; each program includes one or more states. When a user leaves a state in an interactive program by selecting a second state, the system saves state information sufficient to restore the first state. When the user elects to return to the first state, the system retrieves the state information and uses it to restore the first state; if the first state is not in the same interactive program as the second state, the system terminates the second state's interactive program and launches the first state's interactive program.
