GLOSSARY
■
HDMI
HDMI (High-Definition Multimedia Interface) is the first
industry-supported, uncompressed, all-digital audio/video
interface. Providing an interface between any source (such
as a set-top box or AV controller) and an audio/video
monitor (such as a digital television), HDMI supports
standard, enhanced or high-definition video as well as
multi-channel digital audio using a single cable. HDMI
transmits all ATSC (Advanced Television Systems
Committee) HDTV standards and supports 8-channel
digital audio, with bandwidth to spare to accommodate
future enhancements and requirements.
When used in combination with HDCP (High-bandwidth
Digital Content Protection), HDMI provides a secure
audio/video interface that meets the security requirements
of content providers and system operators.
