Response: ESC, CMD10, ERC, Vid Mode, Aud Lvl, H Shift, Cont, Color, Tint,
Chroma Det, Luma Det, reserved, EOT
Where: ESC, CMD10 = 1Bh, 3Ah
Inp#
80h = Request current channel
81h - 96h = Input channel requested (1-22)
Vid Mode on System 4xi: ____________________ LDxi _ LQxi
80h = RGBS (composite sync) ______________ x ___ x
81h = RGsB (sync on green) ________________ x ___ x
82h = RGBLD (line-doubled RGB video) ________ - ___ -
83h = YC (S-video) ________________________ - ___ -
84h = VID (composite video) _________________ - ___ -
85h = YCLD (line-doubled S-video) ____________ - ___ -
86h = VIDLD (line-doubled composite video) ____ - ___ -
87h = RGBLD - still _______________________ x ___ -
88h = RGBLD - motion ____________________ x ___ -
89h = YCLD - still _________________________ x ___ -
8Ah = YCLD - motion ______________________ x ___ -
8Bh = VIDLD - still ________________________ x ___ -
8Ch = VIDLD - motion _____________________ x ___ -
8Dh = RGBLQ - still ________________________ - ___ x
8Eh = RGBLQ - motion _____________________ - ___ x

90h = YCLQ - motion _______________________ - ___ x
91h = VIDLQ - still _________________________ - ___ x
92h = VIDLQ - motion ______________________ - ___ x
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
82h = Off
83h = not supported

Luma Det
81h-84h = Decoded-modes Sharpness levels 1 - 4
80h = not supported
reserved
80h = reserved
EOT
04h = End Of Transmission
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
