Configuring Inputs
As you change the input
Type
, the default
Colorspace
setting changes, too. For example,
if you select YP
b
P
r
or YC, the Colorspace changes to SMPTE. If you select RGB, the
Colorspace changes to RGB. For details about these options, refer to
on this page.
When you auto-acquire a signal, type selections are limited depending on the input
selected. For example, if
Input 3
is connected to an HDMI source, HDMI is the only option
for that input and cannot be changed.
When you are not auto-acquiring a signal, you can choose a type for the selected input. If
you choose a type that is not applicable to the input, the
Status Menu
displays the
Invalid
Signal
message. For information about auto acquisition, refer to
on page 72.

The
Colorspace
defines the Composite Video Standard for an input. The options available
depend on the selected input and the input

1:1 Sample
sets the sampling mode for the selected input. This option is either
On
or
Off
.
You can turn this option

only for RGB and YP

analog
inputs. For all other input
types, the sampling clock is inherently 1:1.
Image
sampling
occurs when an analog image is digitized, changing the analog signals
(Red, Green, and Blue, for example) into pixels stored in the ImagePRO-II’s image
memory. Using 1:1 sampling
,
the ImagePRO-II samples the analog video at exactly the
same rate as that of the original signal.
