7-6. Glossary
Adobe RGB
This is a definition 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 fields as printing etc.
DCI (Digital Cinema Initiatives)
The company was founded by an association of U.S. film studios, and this company decides the 
specifications for digital cinema.
DisplayPort
VESA provides the digital interface standard for the digital display device. DisplayPort can transfer the 
video signal up to 16 bits for each channel of RGB, and the audio signal too.
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.
EBU (European Broadcasting Union)
The organization also includes broadcasting offices from Europe and North Africa, and it’s role is to decide 
various technical standards etc.
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 filter. 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 filter.
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 
high-contrast image.
  
						

							49Chapter7Reference
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.
Overdrive
This technology enhances response speed by increasing the potential difference at the time of motion of 
liquid-crystal pixels, and it is used for liquid-crystal TV sets and others in general. It provides clear-cut 
three-dimensional display with little afterimage, by improving response speed of the intermediate graduation 
range that frequently appears in moving images.
Rec709
Digital broadcasting (HDTV) standards defined by the ITU-R (International Telecommunication Union 
Radio Communication Sector).
Resolution
The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. This 
monitor consists of  horizontal 2560 pixels and 1440 vertical pixels. At a resolution of 2560 x 1440, all pixels 
are illuminated as a full screen (1:1).
SMPTE-C
One of the standards provided by the SMPTE (Society of Motion Picture and Television Engineers).
sRGB (Standard RGB)
International standard for color reproduction and color space among peripheral devices (such as monitors, 
printers, digital cameras, scanners). As a form of simple color matching for the Internet, colors can be 
displayed using tones close to those of the transmission and reception devices.
Temperature
Color temperature is a method to measure the white color tone, generally indicated in degrees Kelvin. The 
screen becomes reddish at a low temperature, and bluish at a high temperature, like the flame temperature.
5000 K: Slightly reddish white
6500 K: White referred to as daylight-balanced color
9300 K: Slightly bluish white
TMDS (Transition Minimized Differential Signaling)
A signal transmission system for digital interface.
