3.2.2.4 V_OFFSET_ODD
This defines the number of lines from the V_IN pin EAV transition to the end of the
odd active video field region. This parameter has a maximum value of 255. Eight
bits within the host interface are dedicated to this parameter. This parameter has
been added to accommodate all video decoders which that output non-standard
timing for the V_IN signal. See
Figure 3-2: Vertical Offset Definition
.

3.2.2.5 V_OFFSET_EVEN
This parameter defines the number of lines from the V_IN pin EAV transition to the
end of the even active video field region. This parameter has a maximum value of
255. Eight bits within the host interface are dedicated to this parameter. This
parameter has been added to accommodate all video decoders that output non-
standard timing for the V_IN signal. See
Figure 3-2: Vertical Offset Definition
.
3.2.2.6 F_OFFSET_ODD
This defines the number of lines from the F_IN pin EAV transition to the vertical
blanking interval following the odd field. This parameter has a maximum value of
255. Eight bits within the host interface are dedicated to this parameter. This
parameter has been added to accommodate all video decoders that output non-
standard timing for the F_IN signal. See

3.2.2.7 F_OFFSET_EVEN
This register defines the number of lines from the F_IN pin EAV transition to the
vertical blanking interval following the even field. This parameter has a maximum
value of 255. Eight bits within the host interface are dedicated to this parameter.
This parameter has been added to accommodate all video decoders which output
non-standard timing for the F_IN signal. See

3.2.2.8 H_POLARITY
This register defines the polarity of the H_IN pin. With H_POLARITY set LOW, a
falling transition on the H_IN pin indicates end of active video. With H_POLARITY
set HIGH, a rising transition on the H_IN pin indicates the end of active video. One
bit within the host interface is dedicated to this parameter.
