ABSTRACT:
A chroma-decoder1has two SRCs17and21.The first SRC17performs down-conversion, changing the sampling rate of a composite video signal sampled with a system clock signal Cs to the sampling rate (14.3 MHz) of an NTSC signal. The signal generated by the SRC17is output in synchronism with the system clock signal Cs. The signal is then divided into a luminance signal Y and a color-difference signal C, which are subjected to chroma decoding. The second SRC21performs down-conversion, changing the sampling rate of the luminance signal and color-difference signal of the NTSC signal to the sampling rate (13.5 MHz) of an ITU-R601 standard.
