ColourBurst:
In colour TV systems, a burst of subcarrier frequency located on the back part of the composite
video signal. This serves as a colour synchronizing signal to establish a frequency and phase reference for the
Chroma signal. Colour burst is 3.58 MHz for NTSC and 4.43 MHz for PAL.
●
Colour Bars:
A standard test pattern of several basic colours (white, yellow, cyan, green, magenta, red, blue, and
black) as a reference for system alignment and testing. In NTSC video, the most commonly used colour bars are the
SMPTE standard colour bars. In PAL video, the most commonly used colour bars are
eight full field bars. On
computer monitors the most commonly used colour bars are two rows of reversed colour bars
●
Seamless Switching:
A feature found on many video switchers. This feature causes the switcher to wait until the
vertical interval to switch. This avoids a glitch (temporary scrambling) which often is seen when switching between
sources.
●Scaling:
A conversion of a video or computer graphic signal from a starting resolution to a new resolution. Scaling
from one resolution to another is typically done to optimize the signal for input to an image processor, transmission
path or to improve its quality when presented on a particular display.
● PIP:
Picture-In-Picture. A small image within a larger image created by scaling down one of image to make it
smaller. Other forms of PIP displays include Picture-By-Picture (PBP) and Picture- With-Picture (PWP), which are
commonly used with 16:9 aspect display devices. PBP and PWP image formats require a separate scaler for each
video window .
● HDR:
is a high dynamic range (HDR) technique used in imaging and photography to reproduce a
greater dynamic range of luminosity than what is possible with standard digital imaging or photographic
techniques. The aim is to present a similar range of luminance to that experienced through the human visual
system.
●UHD:
Standing for Ultra High Definition and comprising 4Kand 8Ktelevision standards with a16:9 ratio, UHD
follows the 2K HDTV standard. A UHD 4K display hasaphysical resolution of3840x2160 which is four times the area
and twice both the widthandheightofaHDTV/FullHD(1920x1080) video signal.
●
EDID:
Extended Display Identification Data. EDID is a data structure used to communicate video display
information, including native resolution and vertical interval refresh rate requirements, to a source device. The source
device will then output the provided EDID data, ensuring proper video image quality.
