Pillarbox
A Pillarbox image typically means black “pillars” are placed on either side of an image when it
is up-converted from a 4:3 image to a 16:9 image.
Pillarbox is a selection in the Up-Convert and SD-Cross-Convert list boxes. If Pillarbox is
selected when up-converting a 4:3 image to a 16:9 image, black “pillars” are placed on either
side of the image.

4:3 HD image to a 4:3 SD image.
Letterbox is a selection available in both the Down-Convert and SD-Cross-Convert list boxes. If
Letterbox is selected when down-converting a 16:9 HD image to a 4:3 SD image, black bars are
placed on the top and bottom of the SD image.
