Hi Jeffrey,
18 to 18.5microseconds for the line blanking period is correct. I understand the original active video was 85 microseconds and later on after 405 line TV was result of conversion from 625 the active video become 79 to 80 microseconds.
Very old manuals define the active video as being a fractional value as 17/20.
