●NTSC: The colour video standard used in North America and some other parts of the world created by
the National Television Standards Committee in the 1950s. NTSC utilizes an interlaced video signals.
●PAL: Phase Alternate Line. A television standard in which the phase of the colour carrier is alternated from line to
line. It takes four full images (8 fields) for the colour-to-horizontalimages (8 fields) for the colour-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 625-line, 50-field (25 fps) composite
colour transmission system.

●ST2110: A SMPTE developed standard, ST2110 describes how to send digital video over and IP networks. Video
is transmitted uncompressed with audio and other data in a separate streams.SMPTE2110 is intended principally
for broadcast production and distribution facilities where quality and flexibility are more important.
● SDVoE: Software Defined Video over Ethernet (SDVoE) is a method for transmission, distribution and
management AV signals using a TCP/IP Ethernet infrastructure for transport with low latency. SDVoE is commonly
used in integration applications.
●Dante AV: The Dante protocol was developed for and widely adopted in audio systems for the transmission of
uncompressed digital audio on IP based networks. The more recent Dante AV specification includes support for
digital video.
●NDI: Network Device interface (NDI) is a software standard developed by NewTek to enable video-compatible
products to communicate, deliver, and receive broadcast quality video in a high quality, low latency manner that is
frame-accurate and suitable for switching in a live production environment over TCP (UDP) Ethernet based
networks. NDI is commonly found in broadcast applications.
●RTMP: Real-Time Messaging Protocol (RTMP) was initially a proprietary protocol developed by Macromedia (now
Adobe) for streaming audio, video and data over the Internet, between a Flash player and a server.
●RTSP: The Real Time Streaming Protocol (RTSP) is a network control protocol designed for use in entertainment
20
and communications systems to control streaming media servers. The protocol is used for establishing and
controlling media sessions between end points.

may be compressed.
●API: An Application Programming Interface (API) provides a predefined function which allows access
capabilities and features or routines via a software or hardware, without accessing source code or understanding
the details of inner working mechanism. An API call may execute a function and/or provide data feedback/report.
●DMX512: The communication standard developed by USITT for entertainment and digital lighting
systems.The wide adoption of the Digital Multiplex (DMX) protocol has seen the protocol used for a wide range of
other devices including video controllers. DMX512 is delivered over cable of 2 twisted pairs with 5pin XLR cables for
connection.
●ArtNet: An ethernet protocol based on TCP/IP protocol stack, mainly used in entertainment/events applications.
Built on the DMX512 data format, ArtNet enables multiple “ universes ” of DMX512 to be transmitted using

developed for communication between electronical musical instruments and latterly computers. MIDI instructions are
triggers or commands sent over twisted pair cables, typically using 5pin DIN connectors.
●OSC: The principle of Open Sound Control (OSC) protocol is for networking sound synthesizers, computers, and
multimedia devices for musical performance or show control. As with XML and JSON, the OSC protocol allows
sharing data. OSC is transported via UDP packets between devices connected on an Ethernet.
●Brightness: Usually refers to the amount or intensity of video light produced on a screen without regard to
colour. 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.
21
●Colour Temperature: The colour quality, expressed in degrees Kelvin (K), of a light source. The higher the colour
temperature, the bluer the light. The lower the temperature, the redder the light. Benchmark colour
temperature for the A/V industry include 5000°K, 6500°K, and 9000°K.
●Saturation: Chroma, Chroma gain. The intensity of the colour, or the extent to which a given colour in any image
is free from white. The less white in a colour, the truer the colour 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 with respect to 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
interlaced lines. In a
fields, or two sets of
film, a frame is one still image of a series that makes up a motion image.
●Genlock: Allows synchronisation of otherwise video devices. A signal generator provides a signal pulses which
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.
●Colour Burst: 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
22
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 3840x2160 which is four times the area and twice
both the width and height of a 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.
