Claim:
A manipulating switch comprising a port coupled to an HDMI-CEC source device storing a first CEC logical address matching a first HDMI-CEC cluster tree of a first HDMI-CEC display device; the HDMI-CEC source device is also associated with a second HDMI-CEC cluster tree of a second HDMI-CEC display device through the manipulating switch; in the network view of the second HDMI-CEC display device, the manipulating switch assigns to the HDMI-CEC source device a second logical address which is different from the first CEC logical address; wherein the manipulating switch configured to receive a CEC message from its downstream HDMI-CEC port coupled to the second HDMI-CEC display device, the received CEC message directed to the HDMI-CEC source device but has a CEC logical destination address different from the first CEC logical address; and the manipulating switch is further configured to replace the received CEC logical destination address with the first CEC logical address.
