What is hdmi cec on TV

The latest TV models amaze with their rich functionality. Not everyone knows about all the possibilities that are available to owners of modern TVs. For example, HDMI CEC technology, the name of which means “Home Appliance Control”. This is an interesting and complex system that even the average user should know more about.

What is HDMI CEC on TV

The point of HDMI CEC is that the owner of household appliances can control several devices at once, using only one remote control. The number of devices can reach ten, which opens up truly wide possibilities for their operation. Despite the fact that the presence of CEC wiring is required, the unit may not have its implementation.

One of the features of the system is that for some reason each manufacturer strives to come up with its own special name for it. This circumstance leads to confusion, because a beginner does not know that BRAVIA Sync in Sony units is the same as SimpLink in LG devices.

IMPORTANT! Please note that if all devices are from different manufacturers, their synchronization will not always be possible. It is necessary to clarify in advance whether the devices can connect to each other. A sales assistant in a store can provide this information.

Features and technical implementation of HDMI CEC

HDMI CEC includes a large number of features that can make using your TV or other device much easier.Let's talk about some of them:

1. One of the most important and main commands is the device control menu. With its help, it is possible to control the unit through the menu of another device. This is useful if you are far from the TV and do not have the opportunity to approach it, but another device is at hand.
2. Touch Playback - When playback is started, the unit will turn into the active source.
3. The on-screen menu is a large TV screen, which is equipped with the vast majority of modern models. It will be able to display text that you need to show to someone or just read with maximum comfort.
4. Timer Setting - The timer itself is an incredibly useful feature, and now it can be set and configured not only on the desired device, but also using a TV or other device connected to the HDMI CEC system.
5. Preset translation - if you have a large family, then there are probably several connected TVs in your apartment. Now you can transfer channel tuner settings from one to another, so as not to redo everything manually.
6. Tuner control - you can not only transfer tuner settings, but also change them on another device.
7. One-Touch Recording - With this feature, you can start recording instantly, eliminating the possibility of missing something important while searching for the right button or remote control.
8. Information system - in this way you can request the necessary information about a particular device.
9. Routing control - controls changes in signal sources.
10. OSD device name transfer - this function ensures that the desired names of the units are transferred to the main one.

The technical implementation of the interface occurs in the form of a main wire in the HDMI connector. It is thanks to this that it becomes possible to control several devices using one remote control, which is the main function of the system.

In general, the system is quite simple, but nevertheless really useful and important for users who have a large number of complementary devices in their apartment. Having multiple remotes can be quite confusing and can be easily confused or lost.

If you understand how CEC works, you can easily avoid all these troubles and control your home theater, TV, and media player, holding only one TV remote control in your hands. This will also open up more possibilities, because additional functions of the TV will become known that will help make life even more comfortable.
