The HDMI is a type of digital video and audio connector that replaces the old connectors used in DVD players, TV and video monitors.
HDMI provides an interface between any audio source and digital video, such as Blu-ray, DVD player, computer, etc., to any sound device or digital video, and digital TV as a monitor, for example.
Instead of using multiple cables to connect the audio and video signals from a DVD player to a TV, the idea is that there is only a single cable and connector doing all the necessary links.
The biggest advantage of this pattern is that the audio and video connection are made digitally, so feature best quality.
The main differences between HDMI and DVI is that HDMI supports higher resolutions than the DVI, DVI (Digital Visual Interface) only makes video connection, and the HDMI connector is much smaller than the DVI connector.
There are two main models of HDMI connectors on the market: the type A and type B.
The HDMI cable (with 19 pins) is the most popular, as it has direct compatibility with DVI technology. Meanwhile, the HDMI B excels by allowing high-quality broadcasts, working from dual link system.
