DESCRIPTION⁽²⁾
VectSpatCons
0A7
read; F X X X X X X X X Vector spatial consistency = summation over a field period of absolute
differences of horizontal and vertical components of vectors compared
with those of the neighbour blocks (L, R, U and D); in the comparison,
all vector data is used from the previous estimator run. It should be
noted that a lower figure implies better consistency
BlockErrCnt
0A8
read; F X X X X X X X X burst error count (number of burst errors)
LeastErrSum
0A9
read; F X X X X X X X X least error sum (summation over a field period of the smallest match
error that the estimator has found for each block: indicates reliability of
the estimation process)
YvecRangeErrCntmsb 0AA
read; F
X X X X X X X X Y vector range error count (number of vectors that have a vertical
component that is out of range for upconversion at the chosen
temporal position) (15 to 8)
YvecRangeErrCntlsb 0AB
read; F X X X X X X X X Y vector range error count (7 to 0)

X X X X X X X X read out of (number of input (run-) lines − 40) used in previous field
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.
