Abstract :
In this paper, we propose an extended differential pulse code modulation (DPCM) method for sources with unknown parameters (of any theoretical class). The main features of the method are long-term prediction and backward adaptation by forward analysis with a dynamically adjustable prediction precision criterion. The predictors of the encoder and the decoder are synchronized by commands via a logical pipe. The proposed structures can be implemented thoroughly in hardware.
