  • Abstract
    Predictors operating on video signals sampled at six times the color subcarrier (6f_{c}) have been investigated and compared with predictors operating at three times the color subcarrier (3f_{c}) . When the best 6f_{c} predictor is used with an adaptive delta modulator (ADM) step size generator, the resulting pictures are similar in quality to 3f_{c} predictors operating with a four-level adaptive DPCM quantizer. An ADM coder was implemented in real time. The coder used between 24 and 34 IC\´s, depending upon the algorithm, and fits on a single 9 in × 6 in PC board. The transmission rate is 21.4 Mbits/s.
