Chapter 4 Basic Operations for Image Creation
4-21
A 3.5-M/E system includes a program/preset (PGM/PST) bank, which
provides control of the final program output, with background transitions and
up to four downstream key insertions.
You can control downstream key transitions either from the transition control
section or from the downstream keyer control section, but this section
concentrates on operations using the transition control section.
For details of the concept of downstream keying and the downstream keyer
control section, see the section “Basic Downstream Key Operations” (page
4-24).
Overview
Types of transition which can be carried out
You can carry out any of the following types of transition on the backgrounds
or to insert or remove any of the four keys.
• Cut
• Dissolve (normal mix dissolve only)
• Wipe
• DME wipe (single mode only)
DME wipe requires the optional BKDS-7180 DME Interface Board in the
DMK-7000.
All of these transitions except DME wipe can be applied to either the
backgrounds or any of the keys, or any combination of the two. You can use
a DME wipe only for a background transition or for a single downstream key.
Basic Operating Procedure
The following is the basic procedure for carrying out a transition on the
program/preset bank.

buttons.
