NDI is commonly found in broadcast applications. world created by the National Television Standards Committee in the 1950s. NTSC utilizes an interlaced video signal.
• PAL: Phase Alternate Line. A television standard in which the phase of the color carrier is alternated from line to line. It takes four full images (8 fields) for the color-to-horizontal images (8 fields) for the color-to-horizontal phase relationship to return to the reference point. This alternation helps cancel out phase errors. For this reason, the hue control is not needed on a PAL TV set. PAL is widely used in needed on a PAL TV set. PAL is widely used in Western Europe, Australia, Africa, the Middle East, and Micronesia. PAL uses a 625-line, 50-field (25 fps) composite color transmission system.

• Brightness: Usually refers to the amount or intensity of video light produced on a screen without regard to color. Sometimes called black level.
• Contrast Ratio: The ratio of the high light output level divided by the low light output level. In theory, the contrast ratio of the television system should be at least 100:1, if not 300:1. In reality, there are several limitations. Well-controlled viewing conditions should yield a practical contrast ratio of 30:1 to 50:1.
• Color Temperature: The color quality, expressed in degrees Kelvin (K), of a light source. The higher the color temperature, the bluer the light. The lower the temperature, the redder the light. Benchmark color temperatures for the A/V industry include 5000°K, 6500°K, and 9000° K.
• Saturation: Chroma, Chroma gain. The intensity of the color, or the extent to which a given colour in any image is free from white. The less white in a colour, the truer the color or the greater its saturation. Saturation is the amount of pigment in a colour and not the intensity.
• Gamma: The light output of a CRT is not linear concerning the voltage input. The difference between what you should have and what is actually output is known as gamma.
• Frame: In interlaced video, a frame is one complete image.A video frame is made up of two fields, or two sets of interlaced lines. In a film, a frame is one still image of a series that makes up a motion image.
• Genlock: Allows synchronization of otherwise video devices. A signal generator provides a signal pulse that connected devices can reference. Also, see Black Burst and Color Burst.
• Blackburst: The video waveform without the video elements.It includes the vertical sync, horizontal sync, and the Chroma burst information. Blackburst is used to synchronize video equipment to align the video output.
• Color Burst: In color TV systems, a burst of subcarrier frequency is located on the back part of the composite video signal. This serves as a color synchronizing signal to establish a frequency and phase reference for the Chroma signal. Color burst is 3.58 MHz for NTSC and 4.43 MHz for PAL.
• Color Bars: A standard test pattern of several basic colors (white, yellow, cyan, green, magenta, red, blue, and black) as a reference for system alignment and testing. In the NTSC video, the most commonly used color bars are the SMPTE standard color bars. In PAL video, the most commonly used color bars are eight full-field bars. On computer monitors the most commonly used color bars are two rows of reversed color 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, or transmission path or to improve its quality when presented on a particular display.
• PIP: Picture-In-Picture. A small image within a larger image is created by scaling down one of the images 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 a physical resolution of 3840×2160 which is four times the area and twice both the width and height of an HDTV/FullHD (1920 x1080) 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.
