What is HDMI-CEC? HDMI is an audio/video interface used to transfer data from a source device to a display. HDMI-CEC is an optional feature on many HDMI-compatible devices that allows you to control multiple HDMI devices from a single remote control, such as a TV remote. The CEC in HDMI-CEC stands for Consumer Electronics Control.

HDMI-CEC can greatly simplify your home theater system. HDMI-CEC provides most of the core features you’ll find on any remote. Power, playback, audio, and menu selection information can all be transmitted via HDMI CEC. No more switching between remotes. No more switching between devices on the universal remote.

How Does HDMI-CEC Work?

HDMI-CEC uses any of your device’s remotes to control your entire system. For example, if you are using a TV remote to control a DVD player, the remote communicates with the TV to send the CEC signal to the DVD player via the HDMI cable.

No matter which remote you use, there is a corresponding device to effectively control the other devices it is connected to. They can even control the device during sleep and when the HDMI circuit is disabled or when the device is completely powered down. This is because, although CEC is integrated into the HDMI cable, it is a separate electrical signal from other HDMI controls.

Advantages and Disadvantages of HDMI-CEC

Advantages of HDMI-CEC

  • Use the TV remote to control certain functions of devices connected to the TV via HDMI, reducing the need for a universal remote.
  • The same HDMI cable that connects the audio and video components can be used as a conduit to control these devices.

Disadvantages of HDMI-CEC

  • Not all HDMI-equipped devices must include CEC functionality.
  • On devices that include HDMI-CEC, feature access is not always consistent when using mixed-brand components.
  • Not as comprehensive as using the remote or universal remote that came with the device.
  • In some cases, HDMI-CEC must be activated for HDMI-ARC to also work.
  • Sometimes HDMI-CEC will activate or deactivate the device when you don’t want it.

Generic name for HDMI-CEC
