| 1992 | Invention patented by Noboru Kawayachi and Toru Shibuya on September 17th, 1992. Abstract: 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. |
