PRODUCT SPECIFICATION
In fields 5, 6, 7, and 8 the U and V vectors are 180 degrees
advanced from fields 1, 2, 3, and 4.
Composite, PAL Field-Based Comb Filters
In PAL field based comb decoders, there is an external delay
of 312 lines, therefore the 2 adjacent picture lines 0H and F0H
are 180 degrees apart. In fields 5, 6, 7, and 8 the U and V
vectors are 180 degrees advanced from fields 1, 2, 3, and 4.
