Setting the Gain Levels

There are eight controls that set the gain of the video. With these controls the user can adjust the gain of
the 3 components in either the Y Cr Cb domain or the R G B domain over a range of -50% to 100% in
0.1% steps. Move the relevant slider bar to the left to decrease gain. Move the relevant slide bar to the
right to increase gain. Gain adjustments in the Y, Cb, Cr domain are made first, then gain adjustments in
the RGB domain. Illegal values are clipped after gain adjustments.
Y Gain Ranges from –50% to 100% in 0.1% increments.
Cb Gain Ranges from –50% to 100% in 0.1% increments.
Cr Gain Ranges from –50% to 100% in 0.1% increments.
R Gain Ranges from –50% to 100% in 0.1% increments.
G Gain Ranges from –50% to 100% in 0.1% increments.
B Gain Ranges from –50% to 100% in 0.1% increments.
Saturation Gain Ranges from –50% to 100% in 0.1% increments.
Video Gain Ranges from –50% to 100% in 0.1% increments.

Setting the DC Offsets

There are six controls that independently set the DC Offset of R, G, B, Y, Cb, Cr. With these controls the
user can adjust the DC offset of the various components with a range of +/- 200 quantization levels. Move
the relevant slider bar to the left to decrease applied offset. Move the relevant slide bar to the right to
increase offset.
Y Offset Ranges from –200 to 200 quantization levels in 1 level increments.
Cb Offset Ranges from –200 to 200 quantization levels in 1 level increments.
Cr Offset Ranges from –200 to 200 quantization levels in 1 level increments.
R Offset Ranges from –200 to 200 quantization levels in 1 level increments.
G Offset Ranges from –200 to 200 quantization levels in 1 level increments.
B Offset Ranges from –200 to 200 quantization levels in 1 level increments.

Setting the Hue

With this control the user can adjust the Hue of the video signal.
Hue Ranges from –180 to 180 degrees in 0.1 degree increments.
