Section 2 — Control Panel Descriptions
When an image is read from the frame store in field mode, the
“other” field is replicated from the selected field (indicated by the
illuminated FIELD button), if REPLICATE mode is selected in the
Video Store menu. If INTERPOLATE mode is selected in the menu,
the “other” field is interpolated from the selected field.
A two-field sequence is the normal default image frozen in the
frame store. However, the memory architecture also allows
storage of a complete four-field color frame. A FRAME TYPE
button located in the Frame Store menu allows you to switch
between two-field storage mode and four-field storage mode. At
the present time, either mode allows storage of only one image.
When in four-field mode, not all of the Frame Store functions are
available, but this mode produces the highest quality video, since
there is no decode/encode processing.
