Function
Load Table for Window #2 (WinLoadTab2)
Read Table for Window #2
Vertical Begin (first active video line within a field)
min. line number for 625/50 standards: 7
min. line number for 525/60 standards: 10
max. line number: determined by current TV line standard
Number of input lines
determines the range between the first and the last active
video line within a field; vbeg + vlinei should not exceed the
max. number of lines determined by the current line
standard (exceeding values will be corrected automatically)
enable temporal decimation (0: off, 1: on)
with temporal decimation enabled, only the number of
frames selected in register h’157 (tdecframes) will be output
within an interval of 3000 frames
11: Window disabled
10: Window enabled in ODD fields only
01: Window enabled in EVEN fields only
00: Window enabled in both fields
Number of output lines
vlineout cannot be greater than vlinein (no interpolation);
for vlineout < vlinein vertical compression via line dropping
is applied
hbeg > 0 enables cropping on the left side of the window
reserved (must be set to zero)
hbeg + hlen can not exceed npix
reserved (must be set to zero)
npix must be an even value within the range 32 ... 864
reserved (must be set to zero)
