HDMI is a connector and cable capable of transmitting high-quality and high-bandwidth streams of audio and video between devices. The HDMI technology is used with devices such as an HDTV, Projector, DVD player, or Blu-ray player. HDMI stands for High-Definition Multimedia Interface. The cable transmits data from a source to device such as a TV, computer, laptop, projector or speaker.

The key benefit of HDMI is its ability to transport a high bandwidth of data (video, audio and now 3d and ethernet) using a single cable. For the average consumer, the ability to connect their TV and DVD player with just one cable certainly makes setting up a home entertainment system less daunting.
