Basic Chroma Key Operations

This section describes chroma key operations with the BKDS-2031 board
only installed.
Note that the operation is slightly different in D1 and D2 systems.

Preparations

Dedicated chroma key inputs and settings
• In a D2 system, since one of four analog component signals (the signals
input to the CRK INPUTS connectors on the rear panel of the processor) is
used as the foreground video, inputs and settings for these signals are
required.
The chroma key dedicated inputs requires the BKDS-7133 board. One
Option
board provides for two inputs.
• In a D1 system, since you can select the signal for the foreground on the key
bus, a special chroma key input is not essential.
In a D1 system, however, to select a chroma key foreground signal with a
Option
cross-point button requires the BKDS-7133.
Signal allocation and selection
In order to display the signals for chroma keying (the foreground signal for
chroma keying or the chroma key signal) on a monitor, it is first necessary to
allocate them to cross-point buttons on the control panel.
You carry out this allocation in a setup menu (see page 13-68).
