Even fields
Line delay
The video format is determined from the video sync signal timing parameters. The
switching time is calculated from the vertical sync signal. The given line is counted by the
horizontal sync signal, and after the given line is reached, the line delay counter is
started. The switching is done when the delay counter stops, this way the switching will
be accurate in ± 300 nanoseconds. (The minimum value is 3.75 μs)
The most widely used standard video formats are stored by factory default in according to
SMPTE RP168. Default values can be reloaded row by row, or for the whole table.
6.4.2. Locking to TTL signal
The synchronization signal is taken from the BNC connector. Unlike with other synx
references, the TTL-sync table has actually only one row, as different signal formats are
not identified in this mode.

Delay
The switching is done when the delay counter stops, this way the switching will be
accurate in ± 300 nanoseconds. (The minimum value is 3.75 μs)

Switching on even fields can be enabled or disabled. Set the
line number in which the switching has to be done.
Set the delay in microseconds which will determine the exact
switching time in the given row.
Rising or falling edge can be set to trigger the delay counter.
Set the delay in microseconds which will determine the exact
switching time after the trigger.
