The HDMI provides an interface of communication between any source of digital audio and video, such as Blu-ray, DVD player, computer and etc. for any sound device or digital video, 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 required connections.
The biggest advantage of this pattern is that the audio and video connection are made digitally, so have a better quality.
The main differences between HDMI and DVI is that HDMI supports higher resolutions than DVI, a DVI (Digital Visual Interface) only does video connection, and the HDMI connector is much smaller than the DVI connector.
