10.4.8. Chroma Signal Knee Clipping Process

In cases where the chroma variable gamma circuit input level exceeds 200%, the knee output can be clipped
to a constant level.

Depends on

output level

=CKNEE

(UCKNEE).

Also linked to

CKNEE2=1[h]

(UCKNEE2=1[h]).

The output level depends on the CKNEE (UCKNEE) setting.
Examples:
CKNCLIP=1[h] & (CKNEE=3[h] & CKNEE2=1[h]) -> Output is clipped to 100% chroma knee output at 300%

input and higher.

CKNCLIP=1[h] & CKNEE=4[h] -> Output is clipped to 160% chroma knee output at 300% input and higher.
CKNCLIP=3[h] & CKNEE=4[h] -> Output is clipped to 120% chroma knee output at 200% input and higher.

<Note>
These output characteristics are based on the use of a chroma variable gamma circuit. If overflowing occurs
(e.g., if R-Y and B-Y color difference conversion processes or YC-Mix processes are used in a later step),
clipping or suppression (drop in output level with high input) may occur in the output chroma signal at low
levels.
