Zodiak — User Manual 167
Daily Setups Menus
Both – This limiter mode is similar to Decodable, except that maximum
levels are reduced slightly around yellow and cyan to prevent over modu-
lating an NTSC transmitter.
None – In this mode, no limiting is imposed. Analog signal paths and mon-
itors may behave poorly to some colors produced in this mode.
Aspect Ratio
Select the aspect ratio from 4:3 or 16:9 as desired.
M/E Output Blanking
Set the M/E Program output blanking to either Pass Bus A’s Ancillary Data or
Regenerate Blanking . This sets the output blanking for all the M/Es.
Pass Bus A’s Ancillary Data – Passes the ancillary data from the A bus to the
M/E Program output during the vertical interval.
Regenerate Blanking– Regenerates blanking during the vertical interval.
Command Processing
These controls determine when commands (like source selections or the
initiation of mixes or wipes) will be enacted by the Zodiak system (also
known as field dominance). These controls can be useful for consistent
match frame editing.
Any Field – The action will occur at the start of the next field, either even or
odd. Use this setting if you are not going to edit the video output and want
the fastest response.
Even Field – The action will always occur at the start of the next even field.
This is probably only appropriate if your edit controller is set to edit in the
middle of a frame.
Odd Field – The action will always occur at the start of the next odd field.
This is the normal setting when the video output will be edited. It is com-
patible with most video editing systems that use the frame boundary for
edits.
Default Transform Engine Crop
The Default Transform Engine Crop controls adjust cropping when indi-
vidual Transform Engine channel crop is turned off (see Transform Menus
on page 295 ). This is important because television images are surrounded
by blanking (black). Not all images have the transition to blanking in
exactly the same place. Normally, these blanking variations are hidden at
the extreme edges of the picture and are not visible.
