If the picture size is smaller or equal than 1/9 PIP a true frame mode display for 100Hz
parent standard with a double field repetition rate is possible (display raster ∼∼ϒϒ only).
The picture size is indicated by the horizontal and vertical decimation factors that must
be equal or below 1/3 of undecimated picture size in both directions. This guarantees
enough memory for a joint-line free picture with full vertical resolution. For bigger pictures
only field mode is supported. The 100 Hz frame mode is activated if READD=’1’ for the
above mentioned picture sizes. For an acceptable quality without line flicker or motion
artifacts only the mode ∼∼ϒϒ is supported for HSP and VSP. If the sequence ∼ϒ∼ϒ is
detected, the field mode will be activated again. Continous switching between these
modes is possible, resulting in continous switching between field- and frame mode.
