The PD64084 can operate in the following major four signal processing modes. Mode selection is performed
Operation Modes
3D Y/C separation, Frame-recursive YNR/CNR, each function is independence. So these don't operate at the
same time.

For standard signals, motion-adaptive three-
dimensional Y/C separation is performed.
For nonstandard signals, inter-line Y/C
separation is performed.
Inter-line Y/C separation and Frame recursive
YNR and CNR is performed.
