Specify how MediaConvert handles the display definition segment (DDS). Keep the default, None (NONE), to exclude the
DDS from this set of captions. Choose No display window (NO_DISPLAY_WINDOW) to have MediaConvert include the DDS but
not include display window data. In this case, MediaConvert writes that information to the page composition segment
(PCS) instead. Choose Specify (SPECIFIED) to have MediaConvert set up the display window based on the values that you
specify in related job settings. For video resolutions that are 576 pixels or smaller in height, MediaConvert doesn't
include the DDS, regardless of the value you choose for DDS handling (ddsHandling). In this case, it doesn't write
the display window data to the PCS either. Related settings: Use the settings DDS x-coordinate (ddsXCoordinate) and
DDS y-coordinate (ddsYCoordinate) to specify the offset between the top left corner of the display window and the top
left corner of the video frame. All burn-in and DVB-Sub font settings must match.
