HDMI (High Definition Multimedia Interface) is a specification that combines video and audio into a single digital interface for use with DVD players, digital television (DTV) players, set-top boxes, and other audiovisual devices. HDMI supports standard, enhanced, or high-definition video plus standard to multi-channel surround-sound audio. HDMI Mini C is a connector defined in the HDMI 1.3 specification intended for portable devices. It is smaller than the Type A plug connector (10.42 mm × 2.42 mm) but has the same 19-pins.
