DVD 4:3 Pan-Scan Within 16:9 Pictures Example

In DVD use of MPEG-2 for 4:3 pan-scan within 16:9 pictures, the pan-scan MPEG-2 variables must not violate the restrictions specified in the DXVA_BlendCombination structure. These variables must also maintain the following restrictions required by the DVD specification.

MPEG-2 VariableValue

horizontal_size

720 or 704

vertical_size

480 or 576

display_horizontal_size

540

display_vertical_size

vertical_size

frame_centre_vertical_offset

Zero

frame_centre_horizontal_offset

Less than or equal to 1440 for horizontal_size = 720

Less than or equal to 1312 for horizontal_size = 704

 

The formulation described in MPEG-2 Pan-Scan Example can then be applied directly in this case.
