Waveform - Datavideo TLM-170V Instruction Manual

Waveform

The TLM-170V offers users different waveform options listed as follows:
 Muilt (Vector scope, YCbCr waveform monitoring, histogram and audio meter)
 Y (Y Waveform monitoring)
 YCbCr (YCbCr Waveform monitoring)
 RGB (RGB Waveform monitoring and histogram)
 Off
Note: If Waveform is set to Multi, the Histogram is enabled by default.
Vector Scope
Waveform Monitoring
Waveform monitoring consists of RGB and YCbCr waveforms which are used to measure the
brightness, luminance and chroma of a video signal as shown in the diagram below.
The vectorscope is used to measure the color
information such as Hue and Saturation in a
video image.
Hue: The color markers are red, magenta, blue,
cyan, green, and yellow. The proximity a signal
to one of the markers tells you what color it is.
Saturation: A vectorscope shows you how
saturated your color is and how far away the
signal is from the center indicates how
saturated the color is. For example, if the color
is close to one of those boxes, then that means
that color in the image is very saturated.
Intersecting lines: The line going up towards the
yellow and red colors is the skin tone line on
which the skin color should fall regardless of the
person's race.
