HDMI is called High-Definition Multimedia Interface. HDMI is the most frequently used HD signal for transferring both high definition video and audio over a single cable. HDMI is a digital replacement for analog video standards. HDMI is used both in the commercial AV sector and is the most used cable in homes connecting devices such as digital TV, DVD player, computer monitor, video projector, Blu-ray player, Xbox, PlayStation and Apple TV with the television. 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.
How to Works HDMI Cable:
The picture was roughly square its aspect ratio was 4:3. Its resolution, or the number of dots that make up the picture on the screen, was about 704 x 480 pixels. HDTVs have an aspect ratio of 16:9, so the picture is rectangular. They also have a higher resolution current HDTV standards allow for resolutions of up to 1920 x 1080 pixels.
The picture was interlaced each piece of the moving image was really half a picture, but the pictures changed quickly enough that the human brain didn’t really notice. It’s a set of rules for allowing high definition electronic devices to communicate.
Advantage of the HDMI Cable:
HDMI technology is the global standard for connecting high-definition equipment. HDMI is the intelligent, all-digital interface that delivers both dazzling quality and unmatched ease of use.
HDMI enables loss-less transmission and better quality video at low brightness scenes at higher resolutions.
They enable digital signals to be stored, transmitted and viewed without changes from the original and hence the signal degradation is not prominent.
This is truly a single cable solution as there is only a single cable that carries audio, video and control information.
More than 1,700 of the world’s largest consumer electronics, PC and mobile device manufacturers incorporate HDMI connectivity into their products.
HDMI supports 10 bit, 12 bit and 16 bit (RGB) color depths which can render over one billion colors in good detail.
Many recent mobile phones can produce output of HDMI video via either a micro-HDMI connector or MHL output.
