OPERATION
Select GENERIC if you want to use standard BCD encoding which can be
read by most readers. (See section 3.9.1 for a discussion on how timecode
readers built in to VTR's handle Film edge numbers.) When Generic style
is used, 6 digits of Edge number information plus frames will be placed into
the user bits in the EDGE modes. Maximum footages of 4, 5 or 6 digits
may be used. Digits that are not used for footage numbers are utilized for
the prefix number.
Select EVERTZ if you want to use binary encoding to compress more data
into the available space. When EVERTZ style is used, 7 digits of edge
number information plus frames will be placed into the user bits. Maximum
footages of 4, 5, 6 or 7 digits may be used. Digits that are not used for
footage numbers are utilized for the prefix number. In addition, to the
prefix, footage and frames, three flag bits are encoded into the user bits
that contain the pulldown of the given field.
