<p>A method and system for communicating state information for a target consumer electronic device (519) in a home network to multiple controller devices (515, 520), where the controller devices are each implementing a controller software element that conforms to a different protocol than the other. The target consumer electronic device (519) is represented within the home network by a target software element. A first controller software element conforming to a data driven interaction (DDI) protocol accesses the target software element. A second controller software element conforming to a protocol different from DDI protocol concurrently accesses the target. The first controller software element and the second controller software element cause a change in the state of the consumer electronic device (519). The target software element notifies the first controller software element of the state information for the target consumer electronic device (519). The target software element notifies the first controller software element according to the DDI protocol and notifies the second controller software element according to the protocol different from the DDI protocol. The first controller software element and the second controller software element use the state information to manage their respective user interfaces such that consistency is maintained between the user interfaces.</p> |
