摘要: A differential pulse code arrangement reduces the bit rate of a composite color video signal by sampling at predetermined m times sub-carrier frequency, predicting present sample from reconstructed past samples and forming representative prediction error in first predictive loop. The is further reduced second loop embedded generating corresponding to difference between thereof. quantized encoded for transmission. summing predicted formed responsive sequence signals. m-1th then next occurring generated samples.
