HDMI CEC- An Absolute Guide in 2021
Written by prodigitalweb

What is HDMI CEC? CEC is known as Consumer Electronics Control, which facilitates interface devices controlled with a single remote controller. If you want to cast an interface established TV while on a separate source input (limited TV channel, Cable, USB), the source input will immediately shift to the interface port wherever the Chromecast is joined. Such TVs will power on (when it is powered off) when cast to the Chromecast. For this feature to work, your Chromecast must possess a wall outlet for power and not be plugged into a USB port on the TV.

Manufacturers usually refer to CEC by various titles other than Hitachi. Below few titles are given:

  • Anynet+ (Samsung)
  • Aquos Link (Sharp)
  • BRAVIA Link and BRAVIA Sync (Sony)
  • CE-Link and Regza Link (Toshiba)
  • SimpLink (LG)
  • HDAVI Control
  • EZ-Sync
  • VIERA Link (Panasonic)
  • EasyLink (Philips),
  • Realink for HDMI (Mitsubishi).

Use HDMI CEC to have control on a various device with a single Remote-

The Interface provides an alternative control choice for your home theatre system. It is an audio/video interface utilizing for transferring data from the source device to a display. To work your multiple devices remotely in a controlled manner and regulate them through a single remote, an interface is used. It is generally an optional feature located on various compatible devices that enable you to manage multiple devices from one Remote, such as a TV remote. It can control each other without user intervention for up to 15 devices.

Consumer Electronics Control was developed to permit all devices to join an interface to function as one device. It means that you don’t have to turn off your soundbar or Blu-ray player distinctively– if you switch off your TV, they too will power down. Hence, it is a type of channel to allow devices connected by an interface to manipulate each other for changing inputs, turning the power on and off, changing volume, play/pause, etc. Although, it may already be allowed on a device you already have (you may have to turn it on manually through the settings menu).

HDMI CEC is Worth Using-

The Interface allows you to connect a device to your TV through an interface port to communicate with your TV. After connecting both of the devices through the Interface, the device can control the TV and vice versa. Hence, this leads you to possess your Blu-ray player through your TV remote. For example, your device can quickly transform and make changes on TV’s input whenever it needs to perform some task.

Let’s suppose your Chromecast is connected to your TV, but you’re in no need of the Chromecast right now. Instead, you’re watching TV or playing Xbox. With an interface, you can begin casting to your Chromecast from a different medium, and the Chromecast will convey a signal to the TV, making the TV turn to the Chromecast’s data. You won’t cope with the TV’s remote and switch to the relevant data on your own.

The Interface CEC gives benefits to game consoles. For example, with a PlayStation 4, you can press the controller or the game console itself to bring the console out of the rest mode. The moment you do that, the PlayStation 4 can immediately connect the TV to the correct interface input and save you from trouble.

Whereas, if you connect the TV to the PlayStation 4 input when the PlayStation is in rest mode, the PlayStation will apprehend that you want to operate it and the device mechanically powers it on. But, neither the Xbox One nor the Wii U supports the Interface at present.

AS the devices label their inputs, your Chromecast will appear as “Chromecast” instead of just “HDMI 2.” Although you can generally type in the label as per your liking, the device can do it for you when you use a CEC.

HDMI CEC is Jam-packed with Various Features-

The Interface offers a number of the chief features that you hardly discover in any other remote. Information for power, playback, audio, and menu selection can all be transferred through CEC. It allows you to rely on one remote instead of multiple. Now, one device remote can control all of your devices.

It should be considered that this is not the same technology as a universal remote control. That remote is programmed with the wireless signal patterns of hundreds of consumer products. When you use a universal remote, the controller is directly controlling the device it is associated with.

  1. Separate every device that is connected with the Interface from your TV and the audio system.
  2. Power reset or restart TV.
  3. Attach the interface cable from its output on your audio system to the interface input on your TV
  4. Check the Control settings on the audio system are On.

  7. Check if the audio transmitted to the audio system while you began any of the built-in internet applications on the TV.

Pros and Cons of HDMI CEC –

It has many pros and hardly any cons. And while the pros overcome the cons, there may be chances to impair the Interface or update your system to one that applies eARC. It is a newer standard that enhances the Interface’s features while eliminating the requirement for setup.


As we have earlier told you, it has plenty of benefits as it grants various multiple controls, providing you improved lucid integration of your home theater system. Moreover, the Interface works in association with ARC, known as Audio Return Channel, to lessen the number of cables that must connect various devices. In brief, ARC facilitates audio to move in both ways by bringing down the number of wires you require joining an external source, for example, a Blu-ray player to a TV and A/V receiver. To have the benefits of interface ARC, your devices must possess ARC or eARC ports. Usually, configuring your devices and enabling an interface ARC along with it, but check your device manual to be sure.


The prime hindrance to the Interface is the shortcoming of ARC to give complete quality surround sound. The interface ARC is competent in transferring uncompressed stereo audio or compressed 5.1 surround sound audio.

If you need uncompressed 5.1 sounds or better audio, you’ll have to impair the Interface and ARC on your devices or update media that support interface eARC. Consumer Electronics Control can deliver 5.1 and 7.1 uncompressed audio and handle better high definition forms by Dolby and DTS.
