Vertical expansion
For every output field, the scan rate converter generates a progressive frame. Thus for
every output field period, a progressively scanned frame compensated to the correct
motion is used for vertical expansion in case of Micronas VDU. This yields a highly
improved performance compared with an intra-field zoom.
The table below defines the internal expansion factor ZOOM depending on the RMODE
and VERINT I²C Bus parameter.
