CEC stands for Consumer Electronics Control. Essentially HDMI-CEC-enabled gear, when connected by an HDMI cable, can be controlled through one remote without any programming or setup required. It is an optional part of the HDMI specification. Up to 10 connected devices, including the display, can be controlled via HDMI. CEC is a two-way communication system in which a device sends back an acknowledgement that it received a command, assuring that devices are in their proper state.
In Philips we market the HDMI-CEC feature under the name ‘EasyLink’. HDMI-CEC is an industry standard supported by many brands, under various proprietary names.
