Stretch

Stretch gives you independent horizontal and vertical stretch control. The original aspect

ratio is not maintained using this control. The Stretch control works differently from most

other control screens. It uses

and

buttons to stretch horizontally. The ENTER button takes you to the previous screen, or you

can press the EXIT button on your remote to exit menus.

•

Shift

Shift allows you to move around on a zoomed or stretched image. As you move around,

you expose parts of the picture that were not visible. Shift works only on a zoomed image.

The controls work like Stretch described on the previous page.

Use the

and

navigation buttons to move the image vertically and

to move the image horizontally. The ENTER button takes you to the previous screen, or you

can press the EXIT button on your remote to exit menus.

Auto AR

When Auto AR is enabled, the iScan Duo will set the input aspect ratio settings automatically.

HDMI sources communicate this information to the iScan Duo. Certain formats also have

pre-defined aspect ratios.

For example, the (picture) aspect ratio of high-definition (HD)

video formats is 16:9 while the (picture) aspect ratio of SXGA PC format is 5:4.

When Auto AR is disabled, use Picture and Active aspect ratio menus to manually select the

correct aspect ratio.

•

Zoom

The Zoom control allows you to magnify your picture while maintaining the aspect ratio of

the input image. As the picture magnifies, the area around the the iScan Duos becomes

invisible off the sides, top and bottom of your display.

Use the

and

buttons on your remote to zoom up and down.

In addition, the remote control has a ZOOM

image.

Presets

Presets provides a short-cut to common aspect ratio settings.

16:9 Full Frame

Select this mode when both the picture aspect ratio and the active aspect ratio of the

input image are 16:9. If the active aspect ratio is different, there will be black bars on

the sides or on the top and bottom part of your display.

4:3 Full Frame

Select this mode when both the picture aspect and the active format aspect ratio of the

input image are 4:3. For a 16:9 display there will be black bars on the left and right

side of your display.

4:3 Letterbox

Select this mode when the picture aspect ratio is 4:3 but the active format aspect ratio

of the input image has a 16:9 or larger aspect ratio. Some older DVDs are encoded

in this manner. The iScan Duo will vertically stretch the input image to fill the screen.

Panorama

This mode is a variation of the 4:3 Full Frame mode. The iScan Duo stretches the input

image to remove the black bars on both sides of the display. The middle part of the image

is not stretched. Only the left and right side of the image are stretched.

User Preset

Custom aspect ratio settings including picture and active aspect ratios, zoom, stretch and

shift functions will be saved in User Preset.

Input Adjust

This menu controls the settings on iScan Duo's inputs.

PReP

™

is an exclusive VRS processing technology developed by Anchor Bay.

Standard definition (SD) formats such as 480p, 576p were deinterlaced at some point before

reaching iScan Duo. Deinterlacing is a complex processing technology that has a significant

impact on image quality. The iScan Duo uses Anchor Bay's high performance VRS Precision

Deinterlacing.

High definition (HD) formats such as 1080p50 and 1080p60 are also frequently created by

deinterlacing 1080i50 and 1080i60.

PReP accepts one of the formats mentioned, and converts it back into an interlaced format.

It can then be deinterlaced again using the VRS technology in iScan Duo, which usually

results in a higher quality picture.

The PReP control allows users to disable this function.

480p/576p

Use this menu to enable or disable PReP for 480p/576p formats

1080p 50Hz/60Hz Use this menu to enable or disable PReP for 1080p50/60 formats

•

DeInterlacer

The deinterlacer control is relevant when the input is interlaced (480i, 576i, 1080i50 or 1080i60)

or it is a deinterlaced format and PReP is enabled (480p, 576p, 1080p50 or 1080p60).
