An area can be set to be excluded from the motion compensation process as its content may be
impossible to accurately motion estimate.
For example:- This is useful for signals with ‘Tika Tape’ (scrolling text at the bottom of the
screen), especially if the words or data have no background, and are moving across the bottom of
the screen.
Such text portions of the content do not need Motion Compensation as they move too slowly to
show staggered movement but it can ‘up-set’ the motion compensation algorithm, therefore SP-14
provides a tool to allow you to exclude from the MEMC process the area of screen that has this type
of content whilst the rest of the screen is MEMC processed.
The numbers in the menu are a pixel count to help you position the area you wish to exclude or
mask. The masked area border can be made visible for setting up, and hidden for normal use.
In the picture between the RED lines indicate where the MASK has been set to exclude the area
where the crawling text and its background have been inserted into the picture
