Timing Adjustment Ranges
The following tables apply to the
V6402
and all other modules with the
'SY'
option enabled. The tables
show the range of the timing adjustments possible relative to the external reference signal (Synchroniser
mode) or the range of adjustable input-to-output delay (also known as insertion delay) if a module is being
operated without an external reference, i.e. the incoming video signal itself is used as a 'reference' (Delay
mode).
Note that overall insertion delay results from adding these timing adjustments to an intrinsic delay, which
depends on the module (V6402, V6404, V6406, V6408 or V6418), the mode of operation and the type of
conversion (progressive
↔
interlace, video mode
↔
film mode).

Notes:
1. If the 'FD' option is not installed, the extra 'Field/Frame Delay' on top of any horizontal
and/or vertical timing adjustments is automatically set to zero.
2. If a V6404, V6406, V6408 or V6418 is fitted with the Frame Synchroniser option ('SY')
enabled, the hor. and vert. timing adjustments apply to the output video format. The
Field/Frame Delay applies to the input video format. This means for the V6404 HD Down
Converter for example that a maximum extra delay of just 24 Fields (and not 50!) can be
imposed on top of the intrinsic delay when down-converting from 1080i59 to 525i59.
