摘要：

In this paper, we introduce an improved DPCM coding method for television applications. Our method utilizes adaptive quantization and nonlinear, median type, predictors. Consequently, it is called Median Adaptive DPCM or MADPCM. Simulation results indicate that good picture quality can be achieved with a compression ratio of 2.7:1 (3 bits/pixel). Using a three-dimensional spatio-temporal median type predictor even the compression ratio 4:1 (2 bits/pixel) gives good results.
