Understanding HDMI-CEC

HDMI-CEC (HDMI Consumer Electronics Control) is an evolution of the traditional HDMI port. Physically, HDMI-CEC is a dedicated bidirectional connection on the HDMI cable standard, transmitting signals between compatible HDMI-CEC devices.

HDMI-CEC can operate with a variety of connected devices such as TVs, Blu-ray players, gaming consoles,...

HDMI-CEC

HDMI-CEC enables users to control multiple devices with a single remote, eliminating the need for separate controls for each product. Here is a compilation of HDMI-CEC functionalities. Note that not all devices with HDMI-CEC will support all functions. Implementation of features on the product will depend on the manufacturer.

Functions of HDMI-CEC

Allows users to turn on the TV and the device connected to the TV via HDMI simultaneously with just one button press on the TV remote. For example, if a media player like Apple TV or Chromecast is connected to the TV and powered on, the TV will switch to the corresponding input for that media player, and users can start playing content without changing the input on the TV.

Allows users to turn off or put HDMI-connected devices to standby mode with just a button press on the TV remote. If all connected HDMI devices are in standby mode, the TV will automatically switch to standby mode as well, saving power and ensuring safety for the devices.

Allows users to control other HDMI-connected end devices without switching TV inputs. When the Remote Control Pass-Through feature is activated, users can use the TV remote to control devices connected via HDMI such as gaming consoles, without having to switch between TV inputs.

When the Device Menu Control feature is activated, users can access and control menus on HDMI-connected end devices such as DVD players, decoders, gaming consoles, media players,... directly from the TV remote. This allows users to adjust settings and options on other devices without needing multiple remotes or switching between HDMI inputs on the TV.

When there are multiple sources connected to the TV (such as PC, DVD player, gaming console,...) via HDMI, you can use this Routing Control feature to select the source to play on the TV. This helps users easily switch between HDMI-connected end devices without having to disconnect and reconnect HDMI cables.

Allows users to use the TV remote to adjust the volume on devices connected to the TV via HDMI, such as using the TV remote to decrease the volume of a soundbar.

Enables users to program HDMI-connected devices to turn on or off at a specific time in the future. For example, users can set the TV to turn off at 10:00 PM every day or configure a media player to automatically turn on at 7:00 AM the next day.

With just one press, you can instruct recording devices connected to the TV to capture the content on the TV screen.
