CEC
Consumer electronics control is used to unify remotes of
differing make to perform a given task with one-button touch.
DDC
Display data channel is used to communicate between to the
source and sink to determine sink capabilities. It is also used as
the HDCP key communications channel.
DDR
Double data rate clocks capture data on both the rising and
falling edge of the clock.
EDID
Extended display identification is used to store monitor (sink)
capabilities in an EEPROM.
HBR
High bit rate audio is used to define sample rates greater
than 192 kB.
HDCP
High bandwidth digital content protection is a method of
protecting content from unauthorized digital copying.
HDMI
High-Definition Multimedia Interface is composed of three
TMDS differential data channels and one differential clock
channel. It is defined to include video streams up to 3.7 Gbps
as well as audio.

I
Inter-IC Communications is a Philips two-wire serial bus for
low speed (up to 400 kHz) data.
I
Inter-IC Sound is a serial Philips bus designed specifically
for audio.
LPCM
Linear pulse code modulation is a method of encoding audio
samples.
RGB
Red, green, blue is the standard definition for three-color
graphics and video.
TMDS
Transition minimized differential signaling is the format used
by the three data channels in HDMI. This encodes eight bits
into 10 bits and serializes them.
x.v.Color
This is feature of HDMI v.1.3 in which the color gamut can be
extended or altered beyond the normal range to accommodate a
given sink.
YCrCb
This is a common color format for video where the Y component
is luminance and the Cr and Cb signals are color difference
signals. 4:4:4 defines a Y, Cr, and Cb for each pixel; 4:2:2 defines
a Y for each pixel and a sharing of Cr and Cb between two
sequential pixels. In this manner, compression of 33% is possible.
