● 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 4Kand8Ktelevision standardswith a16:9 ratio, UHD follows
the 2K HDTV standard. A UHD 4K displayhasaphysicalresolution 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.
