Abstract :
A single coefficient block-adaptive predictor is described for encoding of colour television signals. The optimum coefficients were obtained for each block of incoming samples according to the selection of sampling frequency. The results show a reduction in large prediction errors, compared with a nonadaptive predictor, and also improvements in signal/prediction-noise ratio.
