Luminance Processing
The luma component is derived from the composite signal by subtracting the remodulated chroma
information. The luminance signal is then fed to the input of a peaking circuit. Figure 2-2 illustrates the
basic functions of the luminance data path. In the case of S-Video, the luminance signal bypasses the
comb filter or chroma trap filter and is fed to the circuit directly. A peaking filter (edge-enhancer) amplifies
high frequency components of the luminance signal. Figure 2-3 shows the characteristics of the peaking
filter at four different gain settings that are user-programmable by the I2C.

Color Transient Improvement
Color transient improvement (CTI) enhances horizontal color transients. The color difference signal
transition points are maintained, but the edges are enhanced for signals which have bandwidth limited
color components.
