HDMI

High Definition Multimedia Interface (HDMI) is the Latest Standard (better than VGA and DVI) used in Transfer of Digital Audio or Video Data.

HDMI is a compact audio and video interface for transmitting uncompressed digital data. It represents a digital alternative to consumer analog standards, such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. HDMI connects digital audio and video sources like set-top boxes, Blu-ray Disc players, personal computers (PCs), video game consoles (such as the PlayStation 3 and Xbox 360), and AV receivers—to compatible digital audio devices, computer monitors, and digital televisions.
