PURPOSE: A bidirectional CEC system of a 60 GHz frequency band is provided to control an image device in a counterpart side according to states of a sync device and a source device. CONSTITUTION: An HDMI port(120) performs HDMI communication with an image device made of a source device(200) and a sync device(300). A main controller(110) is connected to the HDMI port and a CEC line. The main controller performs bidirectional HDMICEC(High Definition Multimedia Interface-Consumer Electronics Control) communication with the source device and the sync device. The main controller finds/controls states of the source device and the sync device. [Reference numerals] (100) Bidirectional CEC system |
