HDMI is a next-generation multimedia interface standard that stands for High Definition Multimedia Interface. This standard was introduced in April 2002 by seven companies, including Sony, Hitachi, Panasonic, Philips, Toshiba, Silicon Image and Thomson (RCA). The current maximum version is 2.0, with a maximum data transfer rate of 18 Gbps.
Currently, only HDMI has the ability to simultaneously carry audio and video signals over a single data cable, hence its common name "universal high-definition cable". Although functionally similar to RF interfaces, HDMI uses all-digital signal transmission, which avoids the image degradation problems associated with RF connections. The adapter can convert HDMI to DVI, but audio signals will be lost.
High quality HDMI cables can maintain excellent picture quality even over distances of up to 30 meters without signal boosters. The latest 2.0 standard builds on version 1.4 and upscales resolution to 4K*2K ultra-high definition while maintaining 3D and 1080p compatibility.
