converted to the 16:9 aspect ratio high definition image.

When the Output video standard is set to one of the 1080i, or 720p formats
(see section 5.1) there are 7 output aspect ratio choices available.
Select 4:3 Side Panel if the input image is a conventional 4:3 image filling
the compete raster. Images will be normally be upconverted so that the 4:3
image sits in the center of the 16:9 HD raster with side panels. The position
of the image can be set by the 4:3 POSITION menu item.
13:9 Stretch and 14:9 Stretch are like the 4:3 Side panel above except that
they are stretched horizontally to fill more of the raster. 4:3 is equivalent to
12:9 so 13:9 stretches the image by 8% and 14:9 stretches the image 12%.
Select 16:9 Stretch if the input image is a 16:9 image that has been
squeezed to fit into the 4:3 raster (often referred to as anamorphic). Images
will be upconverted so that the 16:9 image width is stretched to fill the
complete 16:9 HD raster.
Select 13:9 Crop or 14:9 Crop if the input image is a letterboxed 13:9 or
14:9 in the 4:3 raster. Images will be upconverted so that the letterboxed
image height is enlarged to fill the complete 16:9 HD raster height. The top
and bottom of the image will be cropped and the output image will have side
panels.
Select 16:9 Crop if the input image is a letterboxed 16:9 in the 4:3 raster.
Images will be upconverted so that the letterboxed image width is enlarged
to fill the complete 16:9 HD raster width. The top and bottom of the image
will be cropped.
Select User Defined if you want to create a custom input and output picture
position and cropping. See section 6.4.3.1 for more information.
