High Definition Multimedia Interface (HDMI) – A basic information guide

HDMI cables are carriers of digital audiovisual signals. They establish a digital connection between a HD device and the source of digital data. The digital information is uncompressed and does not undergo a conversion process before being displayed on the screen. HD DVD players, HD televisions and HD audio systems are electronic devices which have been upgraded to accommodate this technology.
