Samsung patents HDMI feature to stop data drops by sharing load
Samsung has filed a patent for a method that prevents data loss on the HDMI CEC line, which is a thin wire used for basic commands like turning devices on or off. The system works by creating a temporary, secure link between two devices to share the data load, ensuring that commands are not dropped even if the main line is busy.
In the filing’s own words
A method performed by a first device for creating a dynamic link to prevent HDMI CEC line data drop, includes: transmitting, to a second device via an HDMI CEC line, a request message to create the dynamic link between the first device and the second device; receiving, from the second device via the HDMI CEC line, a response message including information associated with one or more connections available for creating the dynamic link; transmitting, to the second device via the HDMI CEC line, based on the information associated with the one or more connections available for creating the dynamic link, an authentication message including authentication data for creating the dynamic link; creating the dynamic link between the first device and the second device based on the authentication data; and controlling at least one of transmission or reception of one or more data items via the dynamic link.
What exactly they claim (claim 1)
1. An electronic device comprising: a communication interface configured to communicate with another device; memory storing instructions; and at least one processor, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to: transmit, to the other device via a High-Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) line, a request message to create a dynamic link between the electronic device and the other device); receive, from the other device via the HDMI CEC line, a response message in response to the transmitted request message, the response message comprising information associated with one or more connections available for creating the dynamic link; transmit, to the other device via the HDMI CEC line, based on the information associated with the one or more connections available for creating the dynamic link, an authentication message comprising authentication data for establishing the dynamic link; create the dynamic link between the electronic device and the other device based on the authentication data; and control at least one transmission or reception of one or more data items via the dynamic link.
