Modern technology has become more complex, but no less in demand. New devices already have other connectivity interfaces. Some time ago, to connect most household players to the TV, we used the RCA connector, which many of us know as “tulip” or “bell”. Now, basically, there is a new HDMI standard. And if we take into account that there are several pieces of equipment at the disposal of many consumers, HDMI splitters help out here.

In particular, these devices are useful in the conduct of any commercial activity. For example, in many shopping centers you can see monitors that display various kinds of advertising information.

What is an HDMI splitter?

A splitter, or otherwise a splitter, means a device that distributes a signal from a source, usually digital, between several devices. But most importantly - the transfer takes place while maintaining the original quality of the information flow. As for the signal itself, it can be both digital video and audio data.

HDMI splitters (splitters): characteristics, purpose, connection

In other words, the flow of information is transmitted via HDMI splitters from one source to all existing "consumers", which are monitors, televisions and other digital equipment with an HDMI connector. The connecting link between the equipment and the splitter is the cables. And in order to maintain the high quality of the transmitted video and sound, a good splitter is equipped with an amplifier.

Modern HDMI devices can transmit high-definition video, including 3D content.

Luxury or necessity?

Some time ago, when digital technology still did not fully overwhelm our life, such devices were more likely a sign of luxury. Now, serious equipment is not as expensive as before. Therefore, HDMI splitters are no longer a luxury, but a necessary measure. In particular, if we consider that HDMI is gradually replacing the old standards.

As mentioned above, splitters are widely used in commerce. Especially they are relevant in stores specializing in the sale of electronics. Here, usually the same image is transmitted to almost all TVs, so that you can evaluate their picture reproduction quality. But in addition to shopping centers and large retail outlets, they are successfully used in clubs and bars, where music is usually always played or a variety of videos are broadcast.

However, digital HDMI splitters can also be useful at home, distributing the signal over the entire area of ​​the apartment. And what to say when it comes to a private cottage or a mansion. In this case, everything depends on the length of the cables.

In what cases you may still need a splitter? It so happens that when buying a TV, it does not always have enough HDMI inputs for the required amount of equipment (home theater, digital television set-top box or the latest Playstation, etc.). And the alternate use of the Blu-ray player and the console somehow does not inspire joy. With a splitter, everything is more convenient at times, although it will have to spend a bit.

Splitter Types

By and large, splitters are divided into varieties based on the number of outlets. That is, the signal from the source will be distributed among how many consumers. They are usually labeled as: 1xN, where N is the actual number of ports. For example, a 1x4 device, which means HDMI splitter 1 input 4 output. Thus, the following types of splitters can be distinguished:

It is worth noting that most of these devices are fully compatible with HDCP (High-bandwidth Digital Content Protection). The most economical device is considered the HDMI 1x2 device, which connects the source to two devices. Possessing an affordable price and excellent functionality, this splitter is an advantageous solution for the home.

Devices with four ports are also very popular, since most consumers have more than 2 units of digital technology. In this case, the usual 1x2 splitter is clearly not enough. As an alternative - HDMI splitter “2 inputs, 2 outputs”.

Electronic devices with ports of 12 or more are unlikely to be suitable for home furnishing, they are relevant in large electronics stores. Almost all splitters are equipped with a USB port to enable software updates.

Protection technology

HDCP technology, or broadband digital content protection, was developed by Intel for the sole purpose of protecting high-quality video from unauthorized copying. In this regard, any digital device must support the standard HDCP. Otherwise, instead of the normal image on the TV screen, you can observe interference in the form of "snowball". In some cases, the picture still appears, but noticeably low resolution - 480p.

Specifications

Virtually any modern device, be it an HDMI splitter “2 inputs, 2 outputs” or a 1x4 splitter (1x8, 1x14, and so on), supports the standard HDMI 1.3 or 1.4. Due to this, it is possible to transmit high-quality video content.

As for such a parameter as the video signal resolution, many devices are distinguished by the presence of support not only Full HD, but also 3D-format, as well as the modern standard 4K, which is gaining momentum. And if now Full HD over time will force out normal HD, then in some future 4K with Full HD will do the same.

Sound, especially for most expensive films, plays a big role because it allows you to immerse yourself in the action itself. Because of this, most HDMI devices support popular digital audio formats:

Another good feature that the HDMI splitter has is that it supports a certain length of standard HDMI cables. It is about 15 meters to the incoming port and about 25 meters to the output connectors.

Connection

How do I connect using an HDMI splitter? In general, there is nothing difficult to understand. For example, a laptop will act as a source, and the signal must be transmitted to 4 TVs. In this case, you need an HDMI 1x4 device. With the help of the cable we connect the laptop with the splitter. In this case, the cable itself must be connected to the HDMI IN connector. Through it, the device will receive a signal from the source.

After that, it remains to connect the other devices with other cables. It can be seen that the question of how to connect an HDMI splitter is easily solved. In addition, some models allow you to combine several splitters into one chain, which is important for electronics stores.
