resolution at 1µ and the minimum timing resolution at 0.037 µs for HD (High

Definition) and 0.74 µs for SD (Standard Definition).

Things to Remember When Using the Timing Display

1. The Timing Display measures the elapsed time between the vertical syncs of two

inputs. The elapsed time is expressed in units of pixels and lines of the selected

input video not of the reference.

2. When referencing a standard definition analog or digital video input to a high

definition video or external tri-level reference input, the line number indication in

the timing display represents standard definition video lines. If the relative timing is

adjusted in high definition video lines, it may take an adjustment of two or more

lines before the line number changes in the timing display. This is due to the high

frequency high definition video lines, which are shorter than the standard definition

video lines represented by the timing display.

3. When referencing a high definition video input to a standard definition analog,

digital video, or external composite (BB) reference input, the line number

indication in the timing display represents high definition video lines. If the relative

timing is adjusted in standard definition video lines, a single video line adjustment

will cause a change of two or more lines in the timing display. This is due to the

low frequency standard definition video lines, which are longer than the high

definition video lines represented by the timing display.

4. The information of the Timing Display should not be used when captured SDI

freeze data is displayed.
