HDMI provides a communication interface between any digital audio and video source such as the Blu-ray, DVD player, computer, etc., for any digital sound or video device, such as a monitor and digital TV, 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 making all the necessary connections.
The biggest advantage of this standard is that the audio and video connections are made digitally, so they have better quality.
The main differences between HDMI and DVI is that HDMI supports higher resolutions than DVI, DVI (
Digital Visual Interface) only makes video connection, and the HDMI connector is much smaller than the DVI connector.See also the meaning of USB.
