Device Selection Indicator with Remote Control

      Disclosed is a method for selecting an appliance, such as a
video machine or a television set, by using a single remote
controller.  In this method, an indicator is attached to each
appliance and is turned on and off in response to signals from a
remote controller.

      This method assumes that a unique identifier is assigned to
each appliance, and that the appliances are capable of wireless
communication with a remote controller.  Moreover, it assumes that an
indicator capable of expressing two statuses, 'on' and 'off,' is
attached to each appliance.

      Details of this method are now given with an example.  The
items A, B, and so on are steps of a procedure for selecting one of
two or more closely spaced appliances by using a single remote
controller.

1.  When a remote controller is triggered, for example, by a user
    pressing a button, it periodically emits a CONNECTION REQUEST
    signal.

2.  When an appliance receives a CONNECTION REQUEST signal, it turns
    its indicator on and periodically emits its identifying signal.
