Abstract
A method and structure for establishing faster transmission of Consumer Electronic Control (CEC) commands between first and second HDMI-compatible devices. The first and second devices may transmit CEC commands via a shared alternate interface, a signaling path distinct from a standard HDMI CEC interface between the first and second devices. Authentication may furthermore be performed prior to use of the alternate interface to confirm that the communication is authorized.
