Glossary
Luminance Luma or Y for short.
Luminance (Y) is used in video systems to convey the brightness, or black
and white component, of the picture. It is paired with Chrominance (C)
which is usually represented as two color-difference components: U = Blue
- Luma, and V = Red - Luma.
RGB sources, such as the output of a camera, are usually converted into
YUV so that video systems can process the brightness (Y) and colour
information (U and V) separately. This is useful as the human eye is more
sensitive to luminance (Y), than to changes in chrominance (UV).
MADI Multichannel Audio Digital Interface
MADI, or AES10, is an industry-standard interface that carries multiple
channels of digital audio. It supports serial digital transmission over coaxial
cable or fibre-optic lines of 28, 56, or 64 channels; and sampling rates of up
to 96 kHz with resolution of up to 24 bits per channel.
ms milliseconds
Unit of time measurement
Nova73 A stand-alone audio routing matrix with networking capabilities; this is a
large matrix related to the mc
2
series of Lawo consoles.
Overload Occurs when the signal level is too large for the system, resulting in signal
distortion.
ProcAmp Video Processing Amplifier.
A device that stablises the composite video signal, regenerates the
synchronising pulses and can make other adjustments to the video signal.
Progressive Scan See Frame.
Routing Signal Routing
Term used to describe the connection made between an input and output.
Sample Rate The speed at which the internal processing of the system takes samples
respective to values from a continuous, analogue audio signal to make a
discrete, digital one. For example, when running at 48kHz, incoming
analogue audio is sampled at a rate of 48000 values per second.
SD Standard Definition
This term refers to video signals that are not considered to be High
Definition (HD). The two most common SD signal types are 576i and 480i,
which use 576 and 480 interlaced lines per video frame. SD video may use
an aspect ratio of 4:3 or 16:9. Please see
Technical Data for supported
video standards.
SDI Serial Digital Interface
Vectorscope A vectorscope is a special type of oscilloscope used in both audio and
video applications to display an X-Y plot of two signals. The aim is to reveal
details about the relationship between the signals.
The pro8 provides a Vectorscope, within its graphical user interface, to
measure the relationship between the different colour components of the
video signal.
