Aud Lvl
C1h - FFh = Audio level (-31dB to +31dB)
H Shift
81h - FFh = Horizontal shift (-63 to +63 in steps of 2)
Cont
81h - FFh = Contrast level (-63 to +63 in steps of 2)
Color
81h - FFh = Color level (-63 to +63 in steps of 2)
Tint
81h - FFh = Tint level (-63 to +63 in steps of 2)
Chroma Det
81h = On

Example:
Request Configuration for Input Channel #4:
1Bh, 3Ah, 84h, 04h
Response example:
Input #4 is configured for line-doubled S-video (motion), Audio at 0dB and all
picture controls (H Shift, Contrast, Color and Tint) at mid-range (zero), Chroma
Detail (not applicable), Luma Detail at level 1.
This would be:
1Bh, 3Ah, 80h, 8Ah, E0h, C0h, C0h, C0h, C0h, 82h, 81h, 80h 04h
