4-Ch Video Decoder with 4-Ch Audio Codec, Video Encoder
NVP1114A provides the peaking filter and Gain control for emphasizing or depressing the high-frequency
area to avoid this problem. The luma filter is applied to this purpose and its characteristics can be
controlled by register (Y_FIR_MODE, BANK0, 0x28/38/48/58[3:2]) via I2C interface.
Figure 2.4. Peaking Filter Characteristic
2.7. Chroma Processing
: Chroma processing mainly consists of 3 parts: demodulation, filtering, and ACC(Automatic Chroma-gain
Control). The chroma demodulator receives modulated chroma from YC separator, and generates demodulated
color difference data. Demodulated data must be low-pass filtered to reduce anti-aliasing artifacts. Figure
2.5. shows chroma demodulation and filtering process. Chroma LPF frequency characteristics is demonstrated
in Figure 2.6. Users can select the chroma filter through I2C interface (CLPF_SEL, BANK0, 0x7C[1:0]).
