Offset, Description
For SD SDI channels, the Offset is represented as:
0000000 00.00µ 000.00º, V = 0000,
H =0000
.
For Composite 1, Black 1, and Tri-Black channels, the Offset is represented as:
0000000
00.00µ 000.00º, Fr = 0, V = 0000, H = 0000, Sc = 000
.
This menu pair allows the user to select the timing offset from the SPG reference datum for the
video output they are operating on. The timing offset is defined in two rows which are intimately
linked. Either menu line can be edited - each menu line reflects changes in the other line. A brief
description of the timing offset calculations is given here.
In the top line; the timing offset is a number of pixels delayed from the SPG reference datum.
Where displayed, the offset is also decoded, for information only, as an H offset (in
microseconds) and SC offset (in degrees).
In the top line, the timing offset is editable and is represented as a “large number”:
This “large number” will vary depending on the selected format.
In the bottom line, the timing offset is decoded into picture offsets expressed as:
16
1920x1035/59.94/i
21
1920x1080/23.98/p
17
1920x1080/30/p

Frame offset
Fr=0
where Fr=0-1 or 0-3 depending on the selected video format
Line offset

line of the selected format
Sub-carrier offset
Sc=0000
where Sc=0 up to the total number of sub-pixels that equate
to one cycle of sub-carrier in the selected format
