Function
Position of VACT
bit [11:1]: Delay of VACT relative to the trailing edge of HREF
Vertical Begin
bit [8:0]:
bit [11:9]: reserved (must be set to zero)
Vertical Lines In
bit [8:0]:
bit [9]:
bit [11:10]: field disable flags
Vertical Lines Out
bit [8:0]:
bit [11:9]: reserved (must be set to zero)
Horizontal Begin
bit [10:0]: Horizontal start of window after scaling (relative to npix)
bit [11]:
Horizontal Length
bit [10:0]: Horizontal length of window after scaling (relative to npix)
bit [11]:
Number of Pixels
bit [10:0]: Number of active pixels for the full active line (after scaling)
bit [11]:
Load Table for Window #1 (WinLoadTab1)
Read Table for Window #1
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
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 cannot 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)
