Abstract
Methods and devices for manipulating HDMI-CEC messages transmitted over a network including at least two HDMI-CEC display devices with their associated at least two HDMI-CEC cluster trees that at least partially overlap, and enabling each of the HDMI-CEC display devices to communicate using HDMI-CEC with its associated HDMI-CEC cluster tree according to its current HDMI-CEC network view.
Claims48
A network comprising:
- High Definition Multimedia Interface—Consumer Electronics Control (HDMI-CEC) source devices, at least two HDMI-CEC display devices, and a manipulating switch;
- wherein the manipulating switch is configured to enable each of the display devices to communicate with available HDMI-CEC source devices using HDMI-CEC;
- and
- the at least two HDMI-CEC display devices can control the HDMI-CEC source devices as long as none of the HDMI-CEC source devices transmits a Transition-Minimized Differential Signaling (TMDS) communication;
- and when one of the HDMI-CEC display devices receives a TMDS communication from one of the HDMI-CEC source devices utilizing HDMI-CEC, the remaining HDMI-CEC display devices can still communicate with the other HDMI-CEC source devices utilizing HDMI-CEC.
2 more elements
A manipulating switch coupled to a network comprising at least two High Definition Multimedia Interface—Consumer Electronics Control (HDMI-CEC) source devices and at least two HDMI-CEC display devices;
- the manipulating switch is configured to control the HDMI-CEC network views of at least a subset of the HDMI-CEC devices in the network so as to enable the HDMI-CEC devices to communicate using HDMI-CEC with other HDMI-CEC devices in their own HDMI-CEC network view;
- and
- the at least two HDMI-CEC display devices can control the at least two HDMI-CEC source devices as long as none of the HDMI-CEC source devices transmits a Transition-Minimized Differential Signaling (TMDS) communication;
- and when one of the HDMI-CEC display devices receives a TMDS communication from one of the HDMI-CEC source devices utilizing HDMI-CEC, the other HDMI-CEC display devices can still communicate with the other HDMI-CEC source devices utilizing HDMI-CEC.

A method comprising:
- manipulating High Definition Multimedia Interface—Consumer Electronics Control (HDMI-CEC) messages transmitted over a network comprising at least two HDMI-CEC display devices with their associated at least two HDMI-CEC cluster trees that at least partially overlap;
- wherein the at least two HDMI-CEC cluster trees comprise HDMI-CEC source devices;
- enabling each of the HDMI-CEC display devices to communicate using HDMI-CEC with its associated HDMI-CEC cluster tree according to its current HDMI-CEC network view;
- and
- the at least two HDMI-CEC display devices can control the HDMI-CEC source devices belonging to their respective HDMI-CEC cluster trees as long as none of the HDMI-CEC source devices transmits a Transition-Minimized Differential Signaling (TMDS) communication;
- and when one of the HDMI-CEC display devices belonging to one of the HDMI-CEC cluster trees receives a TMDS communication from its respective HDMI-CEC source devices utilizing HDMI-CEC, the remaining HDMI-CEC display devices belonging to the other HDMI-CEC cluster trees can still communicate with the other HDMI-CEC source devices belonging to the other HDMI-CEC cluster trees utilizing HDMI-CEC.

A network supporting High Definition Multimedia Interface—Consumer Electronics Control (HDMI-CEC) comprising:
- means for manipulating HDMI-CEC messages transmitted over a network comprising at least two HDMI-CEC display devices with their associated at least two HDMI-CEC cluster trees that at least partially overlap;
- wherein each HDMI-CEC cluster tree comprises at least one HDMI-CEC source device, and the at least two HDMI-CEC display devices are able to communicate using HDMI-CEC with their associated HDMI-CEC cluster trees according to their current HDMI-CEC network views;
- and
- the at least two HDMI-CEC display devices can control the HDMI-CEC source devices belonging to their respective HDMI-CEC cluster trees as long as none of the HDMI-CEC source devices transmits a Transition-Minimized Differential Signaling (TMDS) communication;
- and when one of the HDMI-CEC display devices belonging to one of the HDMI-CEC cluster trees receives a TMDS communication from its respective HDMI-CEC source devices utilizing HDMI-CEC, the remaining HDMI-CEC display devices belonging to the other HDMI-CEC cluster trees can still communicate with the other HDMI-CEC source devices belonging to the other HDMI-CEC cluster trees utilizing HDMI-CEC.
