The first time I wanted to hook up my Xbox 360, HTPC and Blu-Ray player to my old HDTV which had only 1 HDMI port left, I didn’t know what device I should be looking for. I know what I want it to do for me, but I don’t know how to call it for me to Google it. To be honest, I came up with “HDMI hub”, which I borrowed from a network hub which could split network signals for multiple computers. I was also thinking of “HDMI adapter” and “HDMI splitter”. Unfortunately, none of them were the popular names.

Such a product is actually commonly called an HDMI switch or switcher. Of course, there is no official name for it, but there are names more commonly used than others by the majority of the users. So knowing the right names help you research them better and find better prices before you decide to buy one. After reading this article, you will get a much clearer picture of the common names of the many HDMI gadgets and what they do.

1. HDMI Switch, Switcher, Selector

They are the names of an HDMI input switch, which receives signals from multiple HD devices, and output to only 1 port on an HDTV, monitor or projector. This is what you need when you want to hook up all your PS3, BluRay, HD PVR, etc all to a single port on your HDTV because your HDTV has only 1 port left.

A 3×1 or 3 port HDMI switch receives 3 HD signals and outputs to 1 port. So on and so forth. Although they are also sometimes labeled as “HDMI splitters”, they should not be, because they don’t split signals but rather they converges signals into 1 port.

2. HDMI Splitter or Amplifier

In contrast, they are the names of an HDMI output switch, which receives signals from just 1 HD device and outputs to 2 or more HDTVs or monitors. This is what you need when you want to output the same HD signal to 2 or more HDTVs. In a sense, they split or amplify the signals into multiple streams, hence the names.

A 1×2 or 2 port HDMI splitter receives HD signal from 1 device and outputs to 2 screens.

3. HDMI Matrix or Distributor

They are combining the functions of input and output switches, they receive multiple HD signals and output to multiple displays. They are rarely used by average consumers but more commonly used by electronics stores or exhibition hosts who need to display many screens simultaneously with HD signals coming from several devices.

A 4×2 HDMI matrix receives HD signals from 4 input sources and output to 2 HDTVs.

4. HDMI Adapter or Converter

These are very general names, which, however, usually mean a much simpler device that connects HDMI port to another video port such as a VGA or DVI port. An HDMI to DVI adapter means it receives HD signals from an HDMI port and outputs to a DVI port.

Summary

So how can you find the right product you need? Try these simple recommended keywords when you are doing your research:

HDMI Switch: Connecting multiple HD devices to 1 HDMI port on your HDTV.
HDMI Splitter: Connecting 1 HD device to 2 or more HDTVs.
HDMI Matrix: Connecting multiple HD devices to multiple HDTVs.
HDMI Adapter: Connecting HDMI port to another type of video port.

Now that you know the magic words, it will be much easier for you to find your desired HDMI gadgets, enjoy.

Further, having your home karaoke system allows you to have fun without necessarily spending cash for drinks if you were at a bar. It is a great way to bond with the whole family by competing with each other and seeing who has the highest score from the machine’s scoring system.

To be able to set up your , you need to buy the following components:

1. Multi-format Karaoke Disk Player

This is much better than the CDG Player only, which can only play songs in CDG format. You want to make sure your player can play songs that are in VCD, DVD, and mp3 format as well. The only features that you need though are key controls, play, and a quick and easy to operate song selector. Don’t buy models that have feature names you don’t even understand because chances are you’re never going to use those features.

The technologically inclined can use their laptop or PC as a disk player.

2. Microphones

Make sure that you buy a pair of these for those times you want to sing duets. The choice of buying wireless or wired is up to you however you have to keep in mind the positive as well as negative attributes of each of the two. Many are inclined to use the more expensive wireless mic. The problem this type of microphone is
that it has to have noise canceling filters for you to avoid feedback when the mic loses signal. Also you need to have fresh batteries handy because when the power drains, no more singing.

You don’t really need a microphone with out of this world features for simple home use. Any good quality mic whether wired or wireless that has good audio pick up and can handle high and low voice ranges does the job pretty well.

3. Monitor

Any flat screen TV can be used as a monitor and it’s better its a bigger screen so you don’t miss out reading the lyrics.

4. Heavy Duty Stereo Speakers

Not all speakers are designed for a home karaoke system. Karaoke speakers must be able to make you sound like a pro and allows you to eliminate feedback. You have to choose your speakers carefully because not all speakers sound great when you crank up the volume..

5. Mixer / Amplifier

No I’m not referring to the mixing boards that have sliders because they are of more use to a recording studio. What you need is a high quality mixer/amplifier that has controls for channels as well as it has a graphic equalizer.

6. Music

What’s the use of a karaoke system without of course, music? Days before the party, you have to acquire karaoke music stored in discs. If it’s party for the kids, you can stock up on nursery rhymes and songs for kids and the adults can collect songs from their favorite artists then its fun time.

An HDMI Splitter is able to relay multimedia interface video signals with high definition to two or more display devices simultaneously over about 15 meters. A larger distribution and longer length can be achieved by daisy chaining two or more such amplifiers.

All types of HDMI devices such as DVD players, PS3, satellite set-top boxes are supported by these splitters. By using this device, both audio and video signals are transmitted digitally over one cable with zero signal loss. These HDMI splitters support HD resolutions of 480p, 720p, 1080i and 1080p, computer resolutions up to 1920 x 1200 and a bandwidth of 225MHz.

There are many kinds of splitters. One of the differences is the number of outputs which depend upon the type of splitter used. Many models such as 1×2, 1×4 and 1×8 are available. All splitters just have one input. 1×2 splitter refers to the one with 2 outputs, 1X4 splitter with 4 outputs, 1X8 splitter with 8 outputs respectively. You can choose splitter according to your demand. Families or businesses that have many HDMI devices can choose 1×4 and 1×8 version.

How to use this great device? Does it operate complexly? Well, installation of this device is so simple and only cost a second. Just “plug n play” technology! It does not need any software or drivers in order to work. What you need to do is just connect the splitter from the HDMI source to the HDMI Splitter via HDMI Cables.

The HDMI Splitter is perfect for home theaters, digital signage applications, business centers, classrooms, control rooms, conference rooms, casinos, remote monitoring and training facilities, etc. By using a HDMI Splitter (like a HDMI Distribution Amplifier), you can connect plasma TV and a projector to create a home theater set up; by using it you also can get the best picture quality achievable is displayed. What’s more, that will save you a lot of energy and money to buy many HD TVs. That’s really great trouble.

Then HDMI splitter is not just save you trouble, but money too. It makes your life simpler and smarter.

Deciding what to plug in where
The hard part is often just decide which device to connect to any input. Returning again to the wiring article, you will notice that some choices of higher quality cabling results than others.
In general, you want to plug each device in the highest quality input that they will fully support.
For example, if you have an HDTV satellite receiver with component and digital output, and a progressive scan DVD with component output, you’ll ideally want the satellite to connect to an HDMI or DVI input, and a DVD component input.
If you do not have HDMI or DVI, then you want them to plug into each separate component inputs.
Now if for some reason not have at least two component inputs, then the choice gets a bit ugly – can be a component video external switch that lets you manually switch between each source or you can decide much loss in DVD image quality and plug it into an S-video input instead.
In general, each video input also have their own associated set of audio inputs – this is a typical analog stereo (two channels, usually red & white RCA jacks) for composite, S-Video and component, and analog stereo or digital audio coax (or optical) digital inputs (HDMI or DVI).
Some HDTVs have a digital audio input, shared between multiple digital video inputs. If that is the case, then there is usually a menu option on the TV to select which digital video input is connected to the digital audio.
Frankly, if you do, however, digital audio, it’s probably time to look into a surround sound system and audio jack in it instead of the TV. In some systems this can mean you end rumble between two remote controls for both video and audio switch (which is why learning remotes like the Logitech Harmony were invented), or in more advanced systems, everything will plug into a home theater receiver, which then connects to the TV, and provides the audio off the video. But that is another article.
But for the most part, most modern HDTVs and programming resources give you enough input and connection options That with a little planning, you can manage to hook any device up to the TV (at least stereo audio) and use of the TV remote to switch between them.
