Table 53 Field interval denitions for D1 (CCIR 656) SAV and EAV codes; note 1
Note
1. Signals F and V change state synchronously with the end of active video timing reference code at the beginning of
the digital line.

Field detection control
Field detection modes:
Direct mode: FLD signal detected from incoming H/V signals, for timing behaviour see Fig.11.
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.
