Abstract :
Predictors operating on video signals sampled at six times the color subcarrier 
have been investigated and compared with predictors operating at three times the color subcarrier 
. When the best 
predictor is used with an adaptive delta modulator (ADM) step size generator, the resulting pictures are similar in quality to 
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.
