hdmi cec

Consumer Electronics Control (CEC) is a feature of HDMI designed to allow users to command and control devices connected through HDMI by using only one remote control. For example, by using the remote control of a television set to control a set-top box and/or DVD player. Up to 15 devices can be controlled. CEC also allows for individual CEC-enabled devices to command and control each other without user intervention.:§CEC-3.1It is a one-wire bidirectional serial bus that is based on the CENELEC standard AV.link protocol to perform remote control functions. CEC wiring is mandatory, although implementation of CEC in a product is optional. It was defined in HDMI Specification 1.0 and updated in HDMI 1.2, HDMI 1.2a and HDMI 1.3a (which added timer and audio commands to the bus).:§§CEC-1.2,CEC-1.3,CEC-3.1,CEC-5 USB to CEC adapters exist that allow a computer to control CEC-enabled devices.
