12 user scale settings.
Zoom:
Zoom range is from 0.5 to 1.5.
Position:
Position when zoom is < 0 defines
where in the output frame the box
is placed. The box will never move
outside of the frame.
When zoom is > 0 the position
defines which part of the input
picture to use.
A value of 0 is center. Positive
values moves picture to the right
or up. Negative values moves
picture to the left or down.
AFD code:
The AFD code that is inserted is 5
bits. The user can specify the 4
least significant bits here, while
the 5
th
bit is taken from the ‘output
environment’ setting in scale 24.

1080/25i Master scale control block
This block sets the output video
standard and the rules that will be
used to determine the scaling used.
In addition it also controls what
packages will be inserted on the
output to describe the video to
down-stream equipment.
There are 8 different versions of
this block, and at one time only
one will be shown and be able to
receive commands. The reason for
this to allow 8 different XMLs for
the 8 different combinations of
allowed output video standards.
