HDMI, or high definition multimedia interface, is an industry supported specification standard that combines audio and video into a single all-digital interface. It is used to connect a television to a DVD player, set-top boxes, Blu-ray players, digital television (DTV) players and other audio visual devices.
HDMI supports high-definition, enhanced, and standard video and the standard multi-channel surround sound audio. All HDMI cables are HDCP (High Bandwidth Digital Content Protection) compliant. The single, high quality cable is used as an all-digital solution to connect all the components of a home theater system, regardless of the manufacturer. An association of major electronics companies including Silicon Image, Toshiba, Thomson (RCA), Sony, Philips, Panasonic and Hitachi helped develop the high definition multimedia interface.
