Claim One:
1. A method for encoding a digital signal which includes two or more correlated channels each including two or more samples, the method comprising: receiving a current one of the samples of a first of the correlated channels; predicting a predicted current sample of the first channel using one or more previously received ones of the samples of the first channel; receiving a current one of the samples of a second of the correlated channels; receiving a next one of the samples of the first channel; predicting a predicted current sample of the second channel using one or more previously received ones of the samples of the second channel and the next sample of the first channel; measuring a first residual signal between the received current sample of the first channel and the predicted current sample of the first channel; measuring a second residual signal between the received current sample of the second channel and the predicted current sample of the second channel; and encoding each of the first and second residual signals.
