There are two types of signal splitters: software and hardware based solutions. It is easy for someone not familiar with technology (or who relies on the neighbor's kid to help figure out computer questions) to be confused by terminology that is designed for specialized purposes.
The hardware type of video splitter has several different types of models:
VGA and VGA + Audio
Composite , Component and S-Video
Dual and Quad Screen Splitter
DVI and HDMI Splitter
The most basic reason for using these types of signal splitter units is to send the same picture to multiple monitors. For example, when you need to record something from a digital cable broadcast to an older analog VHS recorder, you would use an S-Video splitter to make this happen. This device divides the signal and transmits it down two cables.
The VGA Splitter allows you to display the same image from a single source to multiple VGA monitors. However, if you want to do the same thing with a digital DVI signal then a DVI Splitter would be the correct devices as it displays the same image across multiple DVI monitors.
Dual or Quad Screen Splitters are a bit different as they split the viewable area of the display into 2 or 4 segments. A different image can be displayed in each segment. Have you recently added a Blue-ray disc player or digital video gaming console such as an Xbox to your home entertainment system? Or perhaps you have updated older TVs in each room and not have a high definition television in more than one room. In this case the proper solution is an HDMI Splitter, also known as HDMI Distribution Amplifier. This device allows you to transmit both audio and video from one HDMI source (like the Blue-ray player) to multiple HDMI TVs.
So there you have it. It's easy to see how people can get confused talking about these splitters unless you know the context or purpose of use. If you are connecting electronic and video equipment you need hardware based these signal splitter device. Are you looking for your signal splitting solution? There are many online stores which offer splitting device and technical support. Few of them offers free technical support and fast shipping with product warranty.
