HDMI, which is an abbreviation for High-Definition Multimedia Interface. It is starting to become a common thing in a normal household, even though it’s still somewhat considered an advance form of technology. It has rapidly become a favorable alternative to analog standards such as Radio Frequency (RF), Coaxial Cable, S-Video, VGA, PCs and Video Game Consoles.

Type A has 19 pins and bandwidth support for SDTV, EDTV and HDTV modes. The Type A connector is electrically compatible with single link DVI-D.
This connector has 29 pins and this can carry double the video bandwidth of Type A. For use of high-resolution displays for the likes of QXGA which have the resolution capabilities of around 3840 x 2400.
