Selecting the key type
You can use the following key types on the downstream keyers:
• Luminance key (see page 4-39)
• Linear key (see page 4-40)
• Clean key (see page 4-40)
• Color vector key: this uses a signal combining the luminance and
chrominance signals as the key source. Color vector keying can provide
high quality results on a signal with a low luminance which could not be
used for a luminance keying, provided the color saturation is high.
To use a luminance key requires the optional BKDS-7320 Luminance Keyer
Option
and Border Board.
To use a color vector key requires the optional BKDS-7430 Color Vector
Keyer Board.
Of the above four types of key, you can use luminance, linear and clean keys
on all four keyers simultaneously.
You can use two keyers simultaneously for color vector keys. One is
dedicated to DSK4, and the other is common to DSK1 to DSK3.
Use the following procedure to select the downstream key type.
