●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 4K and 8K television standards with a 16:9
ratio, UHD follows the 2K HDTV standard. A UHD 4K display has aphysical 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.
