What is HDMI CEC

What is HDMI CEC

Have you ever turned off your TV and your SkyStream Android TV Box turns off as well? If so, this is caused by something called HDMI CEC or HDMI Consumer Electronics Control. For the rest of the article we will simply call it CEC.

So what exactly is CEC? CEC is a feature of HDMI 1.4 and HDMI 2.0 which allows different electronic devices to communicate and control other electronic devices through the HDMI cable. For instance CEC can turn off other devices such as a SkyStream Android TV Box when the TV is turned off. It can also be programmed so that when you turn on a device it changes the TV’s input source to the same source as the device that was just turned on.

While HDMI CEC can be mildly convenient for home theater junkies with 15 devices connected to their TV; the normal TV owner is normally confused as to why certain devices are turning on and off when they press the power button on their TV. Most people have no idea what HDMI CEC is and have no real use for it. It’s not a very popular feature and most people do not even know that it exists.

If you think HDMI CEC might be useful for you and your home entertainment center, Please feel free to do some research and set it up for what you would like it to do. But for the rest of 99.9% of people reading this who have no use for it and find it annoying, we will tell you how to turn off this setting.

The best way to make sure that none of the devices connected to your TV do wacky things when you power off your TV is to turn off HDMI CEC in your TV’s settings. While this may sound super easy, it can get confusing depending on what brand or model TV you have in your house.

Most of the big name TV manufacturers have come up with some kind of quirky name for HDMI CEC. Whatever clever name your TV manufacturer has come up with for it, rest assured it is simply HDMI CEC with a different name. Below is a list of some of the names that different TV brands have come up with for CEC.


Samsung – Anynet+
Sony – BRAVIA Link or BRAVIA Sync
Sharp – Aquos Link
Hitachi – HDMI-CEC
Vizio – HMDI CEC
Pioneer – Kuro Link
Toshiba – Regza Link or CE-Link
Onkyo – RIHD (Remote Interactive over HDMI)
LG – SimpLink
Panasonic – VIERA Link or HDAVI Control or EZ-Sync
Philips – EasyLink
Mitsubishi – NetCommand for HDMI

As you can see, it is would be nearly impossible for the average consumer to pick any of these names (besides Hitachi & Vizio) in a setting menu and figure out that it controls other devices through HDMI. Hence the confusion.

So if you have any of these models of TVs, go into your TV’s setting, find this setting, and simply turn it off. This is the best way to keep your TV from telling other devices to turn on or off.

However there is another way to turn the HDMI CEC off on your SkyStream Android TV Box right through the settings. This will stop your TV from being able to turn your SkyStream Box on and off. This will not turn off HDMI CEC on your TV, which will still allow your TV to communicate with other devices.

So let’s show you how you can turn off the HDMI CEC setting on your SkyStream TV Box.
