Abstract
Disclosed are various embodiments of a Consumer Electronics Control (CEC) bridge. In one embodiment, a CEC bridge includes an HDMI interface, a network interface, a processor, and code executable by the processor. The code includes logic that emulates a CEC command directed to any of a cluster of remote HDMI devices, wherein none of the remote HDMI devices are coupled to the device through the HDMI interface.
Claims20
A device comprising:
- an HDMI interface;
- a network interface;
- at least one processor;
- and
- code executable by the at least one processor, the code comprising:
- logic that emulates a CEC command directed to any of a cluster of remote HDMI devices, wherein none of the remote HDMI devices are coupled to the device through the HDMI interface.
3 more elements
A system comprising:
- a sink-side bridge including a first HDMI interface and a first network interface,
- a source-side bridge including a second HDMI interface and a second network interface;
- and
- the sink-side bridge configured to:
- discover any of a cluster of first HDMI devices coupled through the first HDMI interface, the plurality of first HDMI devices including an HDMI sink device;
- and
- notify the source-side bridge, via the first network interface, of a corresponding CEC logical address assignment for each of the discovered first HDMI devices;
- the source-side bridge configured to:
- discover any of a cluster of second HDMI devices coupled through the second HDMI interface;
- and
- request from the sink-side bridge, via the second network interface and in response to a received notification from the sink-side bridge, a CEC logical address assignment for each of the discovered second HDMI devices.
8 more elements
A method comprising the steps of:
- a sink-side bridge discovering any of a cluster of first HDMI devices coupled to the sink-side bridge through a first HDMI interface, the plurality of first HDMI devices including an HDMI sink device;
- a source-side bridge discovering any of a cluster of second HDMI devices coupled to the source-side bridge through a second HDMI interface;
- the sink-side bridge notifying the source-side bridge, via a non-HDMI network, of a corresponding CEC logical address assignment for each of the discovered first HDMI devices;
- and
- the source-side bridge requesting from the sink-side bridge, via the non-HDMI network and in response to the received notification from the sink-side bridge, a CEC logical address assignment for each of the discovered second HDMI devices.
2 more elements
The method of claim 18, further comprising the step of:
- the sink-side bridge emulating CEC behavior of each of the discovered second HDMI devices.
The method of claim 18, further comprising the step of:
- the source-side bridge emulating CEC behavior of each of the discovered first HDMI devices.
