ity and intelligibility.
An audio compression method developed by Germany's
Fraunhofer IIS, which achieves high rates of data compres-
sion by discarding data not readily audible to humans. MP3
can compress data down to rates of approximately 1/11 (128
kbps) while retaining sound quality equivalent to a music CD.
A value that indicates the number of times per second ana-
log signals are sampled for conversion to digital signals. The
sampling frequency for music CDs is 44.1 kHz. Normally, the
higher the sampling frequency, the better the sound quality.

HDMI (High-Defi nition Multimedia Interface) is a standard

the capability of transferring both non-compressed digital
video and multi-channel digital audio through a single cable.
DVI (Digital Visual Interface) is the standard for connection
between PC and display.
HDCP (High-bandwidth Digital Contents Protection) is copy-
right protection technology for prevention of illegal dupli-
