X Set estimator mode; 0 = line alternating use of left and right estimator:
use in progressive scan except with vertical compress. 1 = field
alternating use of left and right estimator: use in field doubling and
progressive scan with vertical compress.
set film mode; 0 = video camera mode; 1 = film mode
select upconversion quality; 00 = full, 01 = economy (DPCM),
10 = single memory with motion compensation, 11 = single memory
without motion compensation
set matrix output mode; 1 = double output, disabling vertical peaking;
0 = normal single output mode; this bit setting is the AND function of
BusGControl bits
Master enable for embrace mode (off or on); SwapMpr in control2
should be at ‘swap’ position to really cross-switch FM1 and FM3 field
outputs. Should be set to logic 0 except in film mode and FM3 is
present.
set memory compression (luminance DPCM) (off or on)
set memory decompression (luminance DPCM) (off or on)
