High-Definition Multimedia Interface, a standard for transmitting high-quality audio and video signals between devices.
Acronym created in 2002 from 'High-Definition Multimedia Interface'. The term combines 'high-definition' (referring to enhanced video resolution) with 'multimedia' (multiple types of media) and 'interface' (connection point between systems).
