What it is
HDMI or Multimedia Data Interface is needed to transfer digital audio and video signals from one device to another. Typically, transmission is carried out to the TV from receivers, media players, game consoles, and so on. Thanks to this connector, you can avoid unnecessary cables, since HDMI ARC allows you to transmit both audio and video signals.
Moreover, he does this in two directions. Thus, instead of several wires, only one is needed. The signal transmitted by the cable has a high video resolution of 1080, as well as high-quality eight-channel audio with a frequency of about 182 kilohertz.
IMPORTANT! When purchasing 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 parameters:
- High throughput of media data equal to 18 Gbit/s;
- Various lengths, which can range from 10 (which is the standard length) to 35 meters;
- DVI standard compatible interface. You can also install various adapters on the cable and use them to connect to devices that do not have an HDMI ARC connector;
- The cable allows you to install additional protection against various interference on it. You just need to put special rings on both ends that will perform 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. No special skills are required to ensure functionality. To do this you need:
- The presence of connectors on the TV receiver that are capable of receiving both sound and image;
- Connectable device for data transfer;
- Availability of HDMI ARC cable;
This cable allows you to turn a simple TV into a full-fledged multimedia center. 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! Typically, this cable is used to connect 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 HDMI ARC for and its functions?
Since the introduction of HDMI, ARC or Audio Return Signal has become one of the most useful technologies. It allows you to transmit video and audio signals from a TV receiver, for example, to speakers or a receiver, using just one cable. It is especially useful when using TVs with the SMART TV function.Such TVs themselves create a sound signal. However, TV receivers do not have very high-quality standard speakers. With HDMI ARC, the audio signal can be transmitted to an external speaker system, without tormenting your ears with the poor sound of TV speakers.
Advantages of the function
Multimedia data transfer technology has a number of undeniable advantages. These include:
- HDMI technology allows you to transmit all currently existing types of audio and video signals using just one wire. This allows you to get rid of a large number of cables that tend to get tangled and interfere;
- Using one cable, you can easily assemble a home entertainment multimedia system. If necessary, it can be easily altered at any time;
- The existing home entertainment network can be converted into a completely digital form, which will make it more comfortable and quite mobile;
- The latest versions of HDMI ARC are fully compatible with previous ones, which eliminates possible connection problems;
- Has very high transmittance. This allows you to broadcast a video signal of the highest quality;
- Convenient and simple setup when connecting, which usually occurs automatically;
- Control with one remote control. This is achieved thanks to CEC technology, which allows you to transmit signals from devices using just one button;
How to turn it on
First of all, the cable must be connected to the appropriate connectors on the TV and the connected device - computer, speakers, home theater, and so on.
Setup and activation usually occur automatically. You just need to find the “Sound Control” item in the TV menu and select the desired option.
The HDMI control option must be turned on, and the “Input Mode” mode must be set to “Auto”.
Before connecting, you must make sure that both devices support ARC technology.
This technology not only eliminates a large number of unnecessary wires, but also allows you to enjoy high-quality images and sound.
