Claim One:
1. A method for encoding one or more source samples of a digital signal, the method comprising: receiving a current sample of the one or more source samples; predicting a predicted current sample using one or more previously received ones of the one or more source samples; limiting the predicted current sample to no more than a maximum predicted sample limit which is a first residual range less than a maximum valid source sample value; limiting the predicted current sample to at least a minimum predicted sample limit which is a second residual range more than a minimum valid source sample value; measuring a residual signal between the received current sample and the predicted current sample as limited; encoding the residual signal by: partitioning the residual signal into a least significant portion which has a number of bits and a most significant portion; representing the least significant portion in binary form using the number of bits; determining a value of the most significant portion; representing the most significant portion as a series of bits having a first predetermined bit value wherein the series has a length equivalent to the value of the most significant portion and is delimited by a bit having a second predetermined bit value.
