between the processing of Super Motion and normal scan (50/60 Hz) signals is
that the interpolator is always
disabled at 33% playback speed, because the Super
Motion signal does not cause parity violation at this particular speed.
Whatever the choice, the resulting picture is thus always a compromise between
stability and resolution. With EVS systems, the operator always has got the choice
between any of the 3 above described techniques: no interpolation, 2-line
interpolation or 4-line interpolation. Even if the operator chooses to use the
interpolation, this process will be automatically disabled when not necessary
(100% playback for 50/60 Hz signal, 33% and 100% playback for 150/180 Hz
signal).
Note
All professional VTRs use line interpolation in PlayVar mode to avoid
vertical jitters.
Default value is interpolator off for all configurations except SuperLSM
configuration in which 4-line interpolator mode is enabled.
