NTSC_PAL : RGB Matrix Selection

0 : RGB matrix uses the PAL/SECAM - Coefficients for the Conversion YUV -> RGB

1 : RGB matrix uses the NTSC - Coefficients for the Conversion YUV -> RGB

Note : The input-dematrix for RGBTXT is always "PAL/SECAM" dematrix !! i.e. at the NTSC-mode the colors are correct only for YUV-input.

WS_ON

: White Stretch Selection

0 : White Stretch is switched off

1 : White Stretch is actived

C[5..0]

: Contrast Adjustment

CONTRAST 000000 (hex 00)

111111 (hex 3F)

minimal position : smalles contrast level

= 20% of maximal contrast

maximal position : maximal contrast

B[5..0]

: Brightness

BRIGHTNESS 000000 (hex 00) minimal position : brightness = -30 IRE

100000 (hex 20) nominal position : brightness = 0
