    Reading the specifications and bigotti's comments this is what I make of it.
    The sequence_display_extension header holds the active display region in pixels (PanScan flag).
    If there's no picture_display_extension header the display is centered.

    If the picture_display_extension header is present a new offset can be given,
    this will be the new centre until a new picture_display_extension header with new offsets is given.
    Offsets are pixel/16 values.

    Can be done for progressive, it's a bit more difficult when there are RFF flags.

    Bigotti5, could you please comment on this, well you know more about it than I do...
    If this is correct I will make a beta for Katjarella.
