HDMI: what is it on TV? We understand the TV connectors

Modern TV models are significantly different from their kinescope predecessors. They have a large set of various functions that expand the usual capabilities of a TV receiver. Many of the functions require a specific connector. The available outputs allow you to connect various multimedia devices. Most TVs have an HDMI ARC connector, sometimes not one. Below is a photo where you can see how the connector looks.

What it is

HDMI or a multimedia interface for data transfer, it is necessary to transfer digital audio and video signals from one device to another. Usually, the transfer is carried out on a TV from receivers, media players, game consoles and so on. Thanks to this connector, you can avoid the appearance of unnecessary cables, since HDMI ARC allows you to transmit both audio and video signal.

Moreover, he carries out this in two directions. Thus, instead of several wires, only one is needed. The signal transmitted by the cable has a high resolution video equal to 1080, as well as high-quality eight-channel sound with a frequency of about 182 kilohertz.

IMPORTANT! When buying a TV, you should make sure that this model is equipped with an HDMI ARC connector. By the way, this output has built-in protection against copying licensed media data.

• The HDMI ARC cable has the following options:
• High bandwidth media data equal to 18 Gb / s;
• Various lengths, which can range from 10 (is a standard length) to 35 meters;
• DVI compliant interface. You can also install various adapters on the cable and connect them to devices that do not have an HDMI ARC connector;
• The cable allows you to install additional protection against various interference on it. It is only necessary to put special rings on its both ends that will carry out this function;
• With the help of special amplifiers and senders, you can significantly increase the distance over which the signal will be transmitted;

Outwardly, it is similar to USB, however, it has beveled corners. To ensure operability does not require any special skills. To do this, you must:

• The presence of connectors on the TV-receiver, which are capable of receiving both sound and image;
• Plug-in device for data transmission;
• The presence of an HDMI ARC cable;

This cable allows you to make a full-fledged multimedia center from a simple TV. To do this, you just need to connect it to the TV receiver at one end and the media device at the other, and then make the necessary settings.

REFERENCE! Usually, this cable connects to a personal computer. The connection must be made when both devices are turned off, otherwise you can burn the corresponding connectors on the devices.

What is it needed for HDMI ARC and its functions

From the moment the HDMI interface appeared, the ARC function or the return audio signal has become one of the most useful technologies. It allows you to transfer video and audio from a TV receiver, for example, to speakers or a receiver, using just one cable. It is especially useful when using televisions with the SMART TV function. Such televisions themselves create an audio signal. However, TV receivers have not very high-quality full-time speakers. With the help of HDMI ARC, the audio signal can be transmitted to an external speaker system, and not torture your ears with the bad sound of the TV speakers.

Feature Advantages

Multimedia transmission technology has a number of undeniable advantages. These include:

• HDMI technology allows you to transfer all the currently existing varieties of audio and video signals with just one wire. This allows you to get rid of a large number of cables, which tend to get confused and interfere;
• Using one cable, you can simply assemble a home entertainment multimedia system. If necessary, it can be easily redone at any time;
• The existing home entertainment network can be converted into a fully digital form, which will make it more comfortable and quite mobile;
• The latest versions of HDMI ARC are fully compatible with the previous ones, which eliminates the possibility of possible problems when connecting;
• It has a very high transmittance. This allows you to broadcast the highest quality video signal;
• Convenient and easy setup when connecting, which usually happens in automatic mode;
• Management with a single remote control. This is done thanks to CEC technology, which allows transmitting signals from devices using just one button;

How to turn on

First of all, the cable must be connected to the appropriate connectors on the TV and the connected device - a computer, speakers, home theater and so on.

Setup and activation usually happen automatically. You just need to find the “Sound control” item on the TV menu and set the desired option.

The HDMI option - control should be turned on while the “Input Mode” mode is set to “Auto” mode.
