Top Things To Consider When Purchasing Video Splitters And HDMI Splitters

Oftentimes when one researches a video splitter or HDMI splitter buy the product description pages that pop-up are complete of technical jargon and audio/video production in-house language that may sound inane or are simply incomprehensible to the uninitiated.

While there are thousands of terms that exist, listing them all is beyond the scope of this article. consequently, if you’re searching for audio/video equipment such as an HDMI or video splitter, our glossary will cover some of the most important terms so that you can make an educated purchasing decision.


A digital audio standard established by the Audio Engineering Society and the European Broadcasting Union.

The basic sampling resolution is 20 bit, 44.1 kHz is the most shared. All HDMI splitters should sustain this standard.

Audio Bandwidth

The range of audio frequencies over which an amplifier or receiver will respond and provide useful output. A good HDMI splitter will carry the complete range of audio bandwidth.

Audio-follow-video Switcher

Sometimes, during the switching or processing of signals, the audio signal is separated from the video signal. In such a case, each signal must be processed, mixed and enhanced separately. This scenario may arise when employing an HDMI or video splitter.

Audio Noise

A hiss (random high frequency noise) or a hum (low frequency noise from the strength-line frequency and its harmonics or ground loops) heard on audio/video equipment. High quality HDMI splitters do not generate noise.


Category 5 cable is an unshielded twisted pair kind cable typically used for Ethernet capability. It supports up to 100Mbit/s at 100Mhz. Category 6 cable supports 1Gbit/s at 250mhz. Typically compatible with most HDMI and video splitter technology.

Composite Audio

A standard analog audio which utilizes RCA jacks for interconnection of elements. Predates HDMI splitters. Some video splitters run first generation video in close closeness to longer distance part cables.

Decibel (dB)

A unit of measurement expressing ratios using logarithmic scales. Usually used as a measurement of audio quantity. High quality HDMI splitters will minimize dB drop.

Dolby (noise reduction)

A technique developed by Dolby(tm) which improves the signal-to-noise ratio by compression and expansion. Great HDMI splitters move Dolby-related technologies faithfully.


Digital Theater Systems sound. The DTV standard. High quality HDMI and video splitters are systems capable with DTS. If running a video splitter, a separate audio channel is required.


To adjust the tonal quality of an audio clip. As with graphic equalizers found in home or auto audio equipment, an equalize effect can raise or cut the original signal at different frequency bands. Good HDMI splitters copy faithful equalization of the original signal. Video splitters must be faithful to color equalization.


Extended characterize Identification Data. A data structure that provided by digital displays to describe capabilities to a video source. Includes name, serial, kind, and other monitor data.

ESD Protection

Electrostatic release Protection. Describes a design characterize that mitigates electrical strength fluctuations that may cause costly damage to electronics and elements. A quality HDMI or video splitter will have this capability.


High-Bandwidth Digital Content Protection. Supports HDTV signals over DVI, HDMI, and D-VHS and prevents copyright protection. Compatible with any HDMI splitter.

HDMI 1.3c

High-Definition Multimedia Interface. A digital audio/video connector. 1.3c released June 2006, with single-link bandwidth of 10.2 Gbits/second. Compatible with any HDMI splitter.


Hertz. A measurement used for audio sampling rate, as in the number of audio samples per second. High quality HDMI and video splitters need to manager a minimum refresh rate.


Denotes an audio system that has 4 complete range channels (Left, Center, Right, Surround).


Multichannel Audio Digital Interface, also known as AES-10 standard.

Sample Rate

The rate at which samples of a continuous signal, such as music or a sound, are captured into a digital representation of the original signal. High quality HDMI and video splitters ensure the best move of greater sample rates.

Video Splitter/HDMI Splitter

An HDMI or video splitter’s purpose is to take an input signal and electronically divided it into two outputs. Powered video splitters work best.
