●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.
