Consumer Electronics Control (CEC) is an HDMI feature designed to allow the user to command and control up-to 15 CEC-enabled devices, that are connected through HDMI,[63][64] by using only one of their remote controls (for example by controlling a television set, set-top box, and DVD player using only the remote control of the TV).[65] CEC also allows for individual CEC-enabled devices to command and control each other without user intervention.

Little did I know that this remote control can be so powerful when it pair with the right equipment. It’s like putting an SSD to an old PC but better. Maybe I’m under estimate or over estimate the greatness, If I had to go out on a limb, I want to say that it’s as good as an iPhone with apps introduce since July 10, 2008.

Just your regular remote control, HDTV with CEC support and a Raspberry Pi 2 — it’s an old new entertainment experience.
