Consumer Electronics Control (CEC) is also commonly used for remote control based applications like IR. Third party control systems can also send CEC control commands to endpoints turning them on and off or switching their inputs. CEC was introduced by HDMI standard, and is a bi‑directional CEC channel.

We can link sources and destinations via CEC communication while the router itself can initiate its own commands for example: „SYSTEM ON” or „STANDBY” commands.
