4-CH AHD1.0 4CH RX and 9-CH Audio Codec
The color demodulator in chroma processing block accepts modulated chrominance data from
Adaptive Comb Filter which generate Cb/Cr color difference data. During active video period, the
chrominance data is demodulated using sin and cos subcarrier data.
2.2. Video Input Formats
NVP6114 supports all NTSC/PAL/COMET/AHD1.0 Video Formats. Table 2.1 show various
Video Formats and Register Setting Value (VIDEO_FORMAT, 0x08~0B[4:0], Bank0 / AHD_MD,
0x5C[6:4], Bank3 ) to support them.
