Single Field Flag
In the following example, an electronic edit has occurred but in this instance there is no disturbance to the 3:2
sequence count. Nevertheless, downstream equipment, which performs some form of interpolation, would
generate a mixed output if fields corresponding to sequence counts 1 and 2 were treated as though there were
from the same film frame. To prevent this, a single field flag is generated which indicates to downstream
equipment that this field should be treated as a single field. In the instance shown, the single field flag is active
for two consecutive fields to indicate that an edit has occurred such that two single fields have been generated
from two original film frames containing different picture material.
