HDMI (High-Definition Multimedia Interface) is the latest standard that is used for high-definition video and audio in consumer electronics. HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed, uncompressed, and LPCM audio (a type of modulation) and auxiliary data. HDMI is a Licensed standard and is manufactured by HDMI Adopters (over 1,100 companies).
( HDMI 1.4 also supports several stereoscopic 3D formats )
HDMI connects digital audio/video sources (such as set-top boxes, DVD players, HD DVD players, Blu-ray Disc players, AVCHD camcorders, personal computers (PCs), video game consoles , tablet computers, and mobile phones) to compatible digital audio devices, computer monitors, video projectors, and digital televisions.
DisplayPort is another type of audio/video interface but it is royalty-free and is supported by many computer companies. Advantages of HDMI over DisplayPort are, support for Consumer Electronics Control (CEC) signals, and electrical compatibility with DVI.
