Modern technology has become more complex, but this is no less in demand. The new devices have already other connection interfaces. Still some time ago for connection to the TV of the majority of household players the RCA connector which many of us is familiar as "tulip" or "bell" was used. Now basically the new HDMI standard is found. And if you take into account that there are several units of equipment at the disposal of many consumers, then HDMI splitters help out.
In particular, these devices are useful in the conduct of any commercial activity. For example, in many shopping centers you can see monitors displaying various kinds of information of an advertising nature.
What is an HDMI splitter?
A splitter, or a different splitter, means a device that distributes the signal from the source, usually digital, between several devices. But the most important thing is that the transmission passes with the preservation of the initial quality of the information flow. As for the signal itself, it can be both digital video and audio data.
In other words, the information flow is transmitted via HDMI splitters from one source to all available "consumers", which are monitors, televisions and other digital equipment with an HDMI connector. The connecting link between the technology and the splitter is the cables. And to maintain the high quality of the transmitted video and audio, a good splitter is equipped with an amplifier.
Modern HDMI devices can transfer high-definition video, including 3D content.
Luxury or necessity?
Some time ago, when digital technology had not fully flooded our lives, such devices were more 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. Especially when you 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 you can evaluate their picture playback 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 be useful in a home environment, distributing the signal throughout the entire area of the apartment. And to be sure, when it comes to a private cottage or mansion. In this case, everything depends on the length of the cables.
In what cases can you still need a splitter? It happens that when buying a TV, he does not always have enough HDMI inputs for the required amount of equipment (home theater, set-top box or the latest Playstation, etc.). And the alternate use of a Blu-ray player and set-top box somehow does not inspire joy. With a splitter, everything is more convenient at times, although you will have to spend a little bit.
Types of splitters
By more accounts, the splitters are divided into varieties based on the number of exits. That is, between how many consumers the signal from the source will be distributed. They are usually labeled as follows: 1xN, where N is the actual number of ports. for example, a device 1x4, which means an HDMI splitter 1 input 4 outputs. Thus, we can distinguish the following types of splitters:
It is worth noting that most of these devices are fully compatible with HDCP (High-bandwidth Digital Content Protection). The most economical is the HDMI 1x2 device, which connects the source to two devices. Possessing affordable cost 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 equipment. In this case, an ordinary 1x2 splitter will clearly not be enough. As an alternative, the HDMI splitter is "2 inputs, 2 outputs".
Electronic devices with ports of 12 or more are hardly suitable for home environment, they are relevant in large electronic stores. Virtually all splitters are equipped with a USB port for the ability to update the software.
HDCP technology, or the protection of broadband digital content, was developed by Intel with the sole purpose of protecting high quality video from unauthorized copying. In this regard, any digital device must support the HDCP standard. Otherwise, instead of a 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.
Virtually any modern device, whether it's an HDMI splitter "2 inputs, 2 outputs" or a 1x4 splitter (1x8, 1x14, and so on) supports the HDMI 1.3 or 1.4 standard. Thanks to this, it is possible to transmit high-quality video content.
With regard to such a parameter as video resolution, many devices differ in the presence of support for not only Full HD, but also 3D-format, as well as the modern standard 4K, which is gaining momentum. And if now Full HD eventually replaces the usual HD, then in the future, the same will be 4K with Full HD.
Sound, especially for most expensive films, plays a big role, since it allows you to completely immerse yourself in the action itself. In this regard, most HDMI devices support popular digital audio formats:
Another good feature that a splitter-splitter HDMI has, is the support of a certain length of standard HDMI cables. It is about 15 meters on the incoming port and about 25 meters on the output connectors.
How is the connection made using an HDMI splitter? By and large, nothing difficult to understand here. Suppose, as a source will be a laptop, and the signal must be transferred to 4 TVs. In this case, you need an HDMI 1x4 device. Using a cable, connect the laptop with a splitter. In this case, the cable itself needs to 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 remaining devices with other cables. It is evident that the question of how to connect an HDMI splitter is solved simply. In addition, some models allow you to connect several splitters into a single circuit, which is actual for electronics stores.
