19.7 Issue 7: NTSC-Japan offset compensation does not work as specified
in Y/C mode
Background (how it should work):
The difference between NTSC M and NTSC-Japan is the non-existing 7.5 IRE offset in
Japan. The offset should automatically change by setting the preferred standard to
NTSC-Japan instead of NTSC M via CSTD[2:0] = 100.
Anomaly description:
The offset adaption does not work in Y/C mode (BYPS = 1), however it does work in
CVBS mode.
Impact:
The picture is too dark and picture content below +5 IRE is limited.
Workaround:

1. Set decoder brightness (DBRI[7:0]) to 80h (drawback: ‘super black levels’ below
2. Set decoder to raw data mode by the LCRn registers and use RAWO[7:0] and
or
RAWG[7:0] to adapt the levels
