the estimation process)

X X X X X X X X Write of [number of input (run-) lines
40] to be used in new field
(actual maximum number of input lines in normal operation: 292;
register value 252). Nominally this is to be set as an exact copy of the
value read from RefLineCountPrev before a new field starts. In case
the effective number of input (run-) lines has increased,
RefLineCountNew should, for one field, be set to 255. This will occur
e.g. with decreasing vertical zoom magnification or changing from
525 lines video standard to 625 lines standard. If this is not done, a
deadlock will occur with too few lines processed correctly by the
motion estimator.
