HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed digital audio/video data from a HDMI-compliant device ("the source" or "input") to a compatible digital audio device, computer monitor, video projector, and digital television. A digital audio/video source for HDMI can include a HDMI-compliant set-top box, DVD player, HD DVD player, Blu-ray Disc player, AVCHD camcorder, personal computer (PCs), video game console (such as the PlayStation 3, Xbox 360 and the Wii U), AV receiver, tablet computer, and mobile phone. HDMI is a digital alternative to consumer analog standards, such as radio frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, or VGA (also called D-sub or DE-15F).
There are a number of HDMI-standard cable connectors available, each of which can be used for any uncompressed TV or PC video format, including standard, enhanced, high definition and 3D video signals; up to 8 channels of compressed or uncompressed digital audio; a CEC (Consumer Electronics Control) connection; and an Ethernet data connection. HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed, uncompressed, and LPCM audio, auxiliary data, and implementations of the VESA EDID.
