2. DIGITAL MIXING
The KS0119 supports digital mixing between the two input channels. Digital mixing is the process of replacing a
selected area in the foreground (Channel A) with the corresponding area in the background (Channel B) according
to the output of the keying function. The result is that the foreground objects appear situated in front of the
background’s. Mixing is an indispensable tool to create special effects, such as animation, picture in picture, and
video overlay. The ability to select a small area to display can be used to reduce or hide the image download time
during presentations. The digital mixing is controlled by the Mixing Control Register (
MXCTR
) and control registers
05h to 0Dh.

2.1. Mixing Methods
The KS0119 supports two types of mixing: RGB/YC and YC/YC.
2.1.1. RGB/YC Mixing
RGB/YC mixing is automatically selected if channel A’s format is either high color or pseudo color. The process
simply replaces channel A’s video with Channel B’s when the output of the Keying function is 1.
2.1.2. YC/YC Mixing
If channel A’s input is YCbCr formatted (format register value greater than 7), then YC/YC mixing is selected. In YC/
YC mixing, when the output of the Keying function is 1, the Channel A’s chrominance components are replaced with
Channel B’s, while the luminance signals are linearly blended according to the equation
where K is a programmable value, from 0 to 7, stored in the
Mixing
Control
register (
MXCTR
). Linear Mixing
preserves the shadows inside the keyed area.
2.2. Keying Methods
The KS0119 supports Window Keying, Index Keying, Chroma Keying, Alpha Keying, External Keying, and certain
combinations of them. These are described in detail below.
