Chapter 8 Glossary

Adobe RGB

This is a denition of the practical RGB color space proposed by Adobe Systems in 1998. The color

reproduction range (color gamut) is broader than sRGB, and is highly adaptable to such elds as printing etc.

Color Space

YUV and RGB, etc. are available. YUV expresses the color by using the luminance (Y), the color difference

of Blue (U), and the color difference of Red (V). RGB does this by using the gradation of the 3 colors, Red

(R), Green (G), and Blue (B).

DisplayPort

DisplayPort is a next-generation digital AV interface that allows connection of the PC, audio, imaging

devices, etc. to the monitor. One cable can transfer sound with images.

DVI (Digital Visual Interface)

DVI is a digital interface standard. DVI allows direct transmission of the PC’s digital data without loss.

This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors.

One is a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and

analog signal inputs.

DVI DMPM (DVI Digital Monitor Power Management)

DVI DMPM is a digital interface power saving function. The “Monitor ON (operating mode)” and “Active

Off (power saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.

Gain

This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by

the light passing through the panel color lter. Red, green and blue are the three primary colors. All the

colors on the screen are displayed by combining these three colors. The color tone can be changed by

adjusting the light intensity (volume) passing through each color’s lter.

Gamma

Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma

Characteristic”. A small gamma value produces a low-contrast image, while a large gamma value produces a

highcontrast image.

HDCP (High-bandwidth Digital Content Protection)

Digital signal coding system developed to copy-protect the digital contents, such as video, music, etc.

This helps to transmit the digital contents safely by coding the digital contents sent via the DVI or HDMI

connector on the output side and decoding them on the input side.

Any digital contents cannot be reproduced if both of the equipments on the output and input sides are not

applicable to HDCP system.
