Frame Aspect Ratio
Frame Aspect Ratio (FAR) consists of two possible ratios: 4:3 or 16:9. DVD discs encoded in a 16:9
frame are sometimes referred to as anamorphic or enhanced for widescreen TV’s. For example, a
non-anamorphic widescreen DVD has a FAR of 4:3.
Active Aspect Ratio
Active Aspect Ratio (AAR) is the aspect ratio of the image or content (movie). This content is typically
stated on the back cover of DVD discs. Some common active aspect ratios are as follows:
1.33:1 (4:3)
1.55:1
1.66:1
1.78:1 (16:9)
1.85:1
2.35:1
To use aspect ratio’s in addition to these, the iScan VP50 provides the option to choose a custom
aspect ratio called User with a range of 1.01:1-3.00:1. These options can be accessed by using the
Aspect button on the remote control.
iScan Image Mapping
The situation when the Frame Aspect Ratio (FAR) is the same as the Active Aspect Ratio (AAR)
is sometimes called Full Frame. This situation is illustrated below.
The iScan VP50 maps the AAR to the Output Aspect Ratio (OAR) in the following three ways:
• When the AAR is greater than OAR, the iScan VP50 puts up Borders at the top and bottom as
shown below:
• When the AAR is less than the OAR, the iScan VP50 puts up Borders on the left and right as
shown below:
