Samsung patents HDMI fix for mismatched ground connections
Samsung has filed a patent for a method that helps devices handle HDMI cables with different grounding standards. If a connected device uses a newer, reinforced ground pin, the system asks the source to adjust the signal so the content displays correctly.
In the filing’s own words
A sink device includes a connector including a first ground (GND) corresponding to a first standard of high-definition multimedia interface (HDMI), and a processor configured to receive a signal from a source device through the connector while the connector is connected to the source device, based on the received signal being of a second standard of HDMI corresponding to a second GND, which is a reinforced form of the first GND, request a correction for the received signal of the second standard to the source device, receive a signal that has been corrected from the an external source device, and provide a content corresponding to the received signal that has been corrected.
What exactly they claim (claim 1)
1. A sink device comprising: a connector including a first ground (GND) corresponding to a first standard of high-definition multimedia interface (HDMI); and a processor configured to: receive a signal from a source device through the connector while the connector is connected to the source device, based on the received signal being of a second standard of HDMI corresponding to a second GND, which is a reinforced form of the first GND, request a correction for the received signal of the second standard to the source device, receive a signal that has been corrected from an external source device; and provide a content corresponding to the received signal that has been corrected.
