V-digital field blanking
Field 1; start (V = 1)
Field 1; finish (V = 0)
Field 2; start (V = 1)
Field 2; finish (V = 0)
F-digital field identification
Field 1; F = 0
Field 2; F = 1
Direct mode: FLD signal detected from incoming H/V signals, for timing behaviour see Figs. 11 and 12.
Forced toggle: FLD signal regularly synchronized to source, but will never stay more than two fields with the same ID.
The circuit expects to detect a field change with every vertical reference edge, if the field does not change (field error),
the circuit change the field ID automatically. If the circuit switch to the wrong sequence i. e. at the beginning of
processing, it will be synchronized after one second where no field error has occurred.
Free toggle: FLD signal toggles with every vertical reference edge, independent of source FID.
