Let’s face it, HDMI has done a lot to curb AV connection issues experienced in the last decade. HDMI lets users enjoy Audio-Video connections over a single cable. Today, it’s the primary connection standard used in Audio-Video devices. Apart from HDMI-ARC, HDMI has another feature known as CEC (Consumer Electronics Control).

With compatible devices and CEC enabled, users can access a settings menu to control elements like power and volume. To enable this feature, it is important for users to consult their user manual or contact the manufacturer of the compatible device.

KEY TAKEAWAYS:

  • CEC allows Audio-Video devices connected through HDMI to communicate with each other. In addition, it will enable a limited amount of control from device to device.
  • Each TV manufacturer has its “CEC” term to market the feature, even though it’s an interoperable standard. For example, Sony uses “BraviaSync” while LG uses Simple link.
  • The HDMI-CEC feature will not support all the functions of every device. You’ll want to use your individual device’s remote control for some complex functions.

This feature can be found on many of the best TVs and Peripherals and makes it possible for devices to work better together. The Consumer Electronics Control feature is, however, disabled by default.

By enabling remote interactive, volume control, and audio control capabilities on compatible devices, users can interact with their TV or peripherals from a remote location. This adds convenience and flexibility to the user experience.

It’s pretty normal if you haven’t encountered this term. It’s because manufacturers don’t call this connection feature HDMI-CEC. Each TV manufacturer has its term to market the feature, even though it’s an interoperable standard. For example, Sony uses “BraviaSync,” LG uses SIMPLINK, Phillips uses EasyLink, and Samsung uses Anynet+.

Another thing you might be unfamiliar with is DLP TVs since they have been discontinued. However, the technology behind them is still in use. A device type like a DLP TV requires a device manual to understand the various components and external devices for optimal performance. Understanding device manuals can help you make better decisions when it comes to device selection and proper installation.

Additionally, you may be interested in learning how to make a regular TV a smart TV to allow you to stream content.

Or you can check out how a blu ray player and smart TV can provide a similar experience when it comes to accessing internet content with your TV. Alternatively, you can connect other devices to your TV to do many different things. For instance, you can connect your laptop to your TV to view your photos or to give a presentation.

What is CEC?

Well, CEC allows Audio-Video devices connected through HDMI to communicate with each other. It allows a limited amount of control from device to device. In addition, it lets commands be shared between devices over the same HDMI connection.

The main advantage of this feature is that it enables the user to control common functions between different devices without switching between remote controls. While most people will agree that this is a nice feature, hearing a voice describe everything you do may not be appealing to everyone.

HDMI device control works by utilizing HDMI-CEC (Consumer Electronics Control) protocols. HDMI-CEC is implemented by HDMI manufacturers such as Sony and Logitech Harmony, enabling users to control their HDMI devices with one universal remote. Therefore, HDMI-CEC makes it possible to easily access the features of multiple HDMI devices with a single remote.

If you are hearing a voice explain what you do on the screen, you will need to turn the narrator off if you don’t like it.

For instance, with your TV CEC feature activated, a viewer can use the TV remote control to adjust the volume level of a connected input device such as a Home Theatre system or a soundbar. It is also possible to turn your TV on and off with an input device’s remote control.

Please note that the HDMI-CEC feature will not support all the functions of every device. You’ll want to use your individual device’s remote control for some complex functions.

Bravia Link and Regza Link are compatible devices for Sony Bravia TVs, while HDAVI control is compatible with Panasonic Viera TVs. To get the most out of HDMI-CEC, ensure your device is compatible with Bravia Link, Regza Link, or HDAVI control before attempting to use the feature.

Insider Tip

Please note that the HDMI-CEC feature will not support every device’s functions. You’ll want to use your individual device’s remote control for some complex functions.

How Does CEC work?

The HDMI-CEC feature uses any of your devices’ remote controls to control the entire system. Therefore, if you use your TV’s remote on your Blu-ray player, the TV remote will communicate with the TV to send an HDMI-CEC signal through the HDMI cable to the Blu-ray player.

Therefore, regardless of the device’s remote control, it will still have control over peripheral devices connected via HDMI. It is even possible to control these devices when they are asleep, the HDMI circuitry is disabled, or even when the device is turned off. A little confusing, right? Even though they are integrated into the HDMI cable, the CEC feature separates electrical signals from other HDMI functions. Talking about signals, it’s important to know what the OPC signal is on a TV since this can indicate some kind of error or problem with your TV.

Warning

The CEC feature offers several capabilities for your TV and connected peripheral devices. It’s, however, essential to note that not all the features listed will work on all HDMI-CEC enabled devices, and compatibility varies between brands.
