    • In a DPCM predictive encoder (or performing DPCM prediction by digitizing a NTSC color television signal with a rate three times of a color sub-carrier frequency, a two-frame predictor which outputs a differential signal over two frames is employed as one of predictors. A predictor switcher adaptively selects one of prediction information as an optimal prediction signal and selects corresponding differential information as an optimal differential signal. This differential signal is quantized by a quantizer. The quantized output and the optimal prediction signal are summed by an adder and supplied to the predictors as a local decoding signal.
    • 在DPCM预测编码器中(或者通过以三倍于彩色副载波频率的速率数字化NTSC彩色电视信号来执行DPCM预测),将采用两帧输出差分信号的两帧预测器作为预测器之一。 预测器切换器将预测信息中的一个自适应地选择为最佳预测信号,并选择相应的差分信息作为最佳差分信号,该差分信号由量化器量化,量化输出和最佳预测信号由加法器相加并提供给 预测器作为本地解码信号。
