#WhatIs? What Is an HDMI Cable?

HDMI stands for “High Definition Media Interface.” But, it’s not just a type of cable, cord, or connector. It’s a technology standard that’s designed to transmit high-definition audio and video signals.

 First of all, HDMI is the best possible way to transmit those signals. This technology can deliver a pure, uncompressed digital signal with crystal-clear images and multi-channel audio.

HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device.

 There are different types of HDMI cables and devices.Originally released in 2002, HDMI 1.0 was the first version of the HDMI standard. Since that release, HDMI has gone through many changes.

The standard is constantly evolving to support new technology and new products. Several versions of HDMI have been developed and deployed since initial release of the technology but all use the same cable and connector.

Other than improved audio and video capacity, performance, resolution and color spaces, newer versions have optional advanced features such, as Ethernet data connection, and CEC (Consumer Electronics Control) extensions.

Many of of these changes are minor. In 2017, for example, HDMI 2.1, was announced. Expected in Q2 2017, this latest format will support higher video resolutions, such as 8K, as well as Dynamic HDR, increased bandwidth with a new 48G cable.

This cable will be backwards compatible with your existing HDMI equipment, so you won’t have to start from scratch
