Up/Cross Converter Aspect Ratios
Since all of the currently supported HD standards have the same 16:9 aspect ratio, there is no need to
perform an aspect ratio conversion when cross-converting between them.
If the V6406/08/18 is fed with an SD input, it will up-convert to the selected HD standard (provided they
have the same frame-rate). The input picture will be scaled appropriately in order to accommodate the
16:9 HD video format. There are four options in the

A/R
menu (

:
A/R Up
for V6418).
They are shown diagrammatically below. Note that some conversion settings result in a loss of parts of the
original picture (indicated by hatched areas).

Cross- & Up-Converter Output Standard Selection
The desired HD output standard must be set manually on the V6406 / V6408 / V6418. This can be done in
the menu
VIDEO
:
O/P Std
. Supported conversions are shown in section 1.3.
When stepping through the menu, the operator sees all implemented HD standards and not just frame-rate
matching modes, so one must be careful that the selected output standard matches with its frame-rate with
the input frame-rate for proper operation.
