Common video modes—refer to EIA/CEA-861-D for more

information.

VGA, SVGA, XGA, SXGA, UXGA

Common graphics modes—refer to www.VESA.org for more

information.

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.

Inter-IC Communications is a Philips two-wire serial bus for

low speed (up to 400 kHz) data.

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

T

his 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.
