Editor Commands
Introduction
This section describes the editor command set used by the Kalypso Video
Production Center and the Zodiak Digital Production Switcher when using
the Kalypso/Zodiak editor protocol. These interface commands follow the
Model 4000 interface closely, and are designed to respond to existing Model
4000 commands from an editor (with a few exceptions - such as E-MEM
transfer). Commands have been extended to provide access to Kalypso and
Zodiak features, like Keyer 3 and 4, which do not exist on the Model 4000.
This allows an existing Model 4000 editor interface to be useful without
modification, or expanded to access new switcher functionality.
In this section the Kalypso and Zodiak systems are generically called
“switcher” when the same commands are used. When differences in the
commands for these models exist, the differences are indicated with notes
or with separate labeled tables.
Note the following for both Kalypso and Zodiak switchers:
• The E-MEM data transfer commands have been replaced with Save and
Load commands. Instead of transferring data over the RS-422 serial line
the Load and Save commands transfers data to and from files located
on the switcher’s internal hard drive. These files may be transferred
from the switcher’s hard drive to the editor using FTP over an ethernet
connection.
• The E3 (Mask) command is not implemented. Mask buses do not exist
on the switcher, instead the Utility buses are used for masking.
• The E8 (Layered) command is not implemented. Split layered mode is
not accessible.
• Access is provided to all 128 switcher sources (see Command C0, C1).
Note the following for Kalypso systems only:
• E-MEM Levels are used differently in Kalypso than in the Model 4000.
The Effects Address in this protocol refer to Kalypso E-MEM enable
groups as identified by the default names. Kalypso may be configured
to assign any E-MEM level to any enable group. This protocol assumes
that the enable group will be referenced even if the E-MEM levels
assigned may change.
• Access is provided to new buses: K3, K4, U1, U, and Aux Bus 1 – 46 (see
Command C0, C1).
• Access is provided to secondary wipe generator (see Command C8)
• Access is provided to Primary and Secondary M/E partitions when
Kalypso is in split mode (via effect address).
