What is HDMI?
High-Definition Multimedia Interface (HDMI) is the first
industry-supported, uncompressed, all-digital audio/
video interface. HDMI components can transmit both
digital audio and video over a single cable with
improved quality over traditional analog connections
due to an all-digital transmission. Transferring digital
sources to display such as DVDs and HDTV
programming can now be done without analog
conversions that can degrade the original signal.
