Scaler and interfaces
Table 144 shows some examples for the scaler
programming with:
prsc = prescale ratio
fisc = fine scale ratio
vsc = vertical scale ratio.
The ratio is defined as:
In the following settings the VBI data slicer is inactive.
To activate the VBI data slicer, VITX[1:0] 86H[7:6] has to
be set to ‘11’. Depending on the VBI data slicer settings,
the sliced VBI data is inserted after the end of the scaled
video lines, if the regions of VBI data slicer and scaler
overlaps.
To compensate the running-in of the vertical scaler, the
vertical input window lengths are extended by
2 to 290 lines, respectively 242 lines for XS, but the scaler
increment calculations are done with 288, respectively
240 lines.
16.5.1
TRIGGER CONDITION
For trigger condition STRC[1:0] 90H[1:0] not equal to ‘00’.
If the value of (YO + YS) is greater than or equal to 262
(NTSC), respectively 312 (PAL) the output field rate is
reduced to 30 Hz, respectively 25 Hz.
Horizontal and vertical offsets (XO and YO) have to be
used to adjust the displayed video in the display window.
As this adjustment is application dependent, the listed
values are only dummy values.
16.5.2
MAXIMUM ZOOM FACTOR
The maximum zoom factor is dependent on the back-end
data rate and therefore back-end clock and data format
dependent (8 or 16-bit output). The maximum horizontal
zoom is limited to approximately 3.5, due to internal data
path restrictions.
