摘要

Described herein is a method for reducing the size of a first digital data set (20) to form a second digital data set (61) that has a smaller size than the first digital data set (61). A first subset (A 0 , A 2 , A 4 , A 6 , A 8 ) of samples (A 0 , A 1 , A 2 . A 3 , A 4 , A 5 , A 6 , A 7 , A 8 , A 9 ) within the first digital data set (20) is equated to a neighbouring second interleaved subset (A 1 , A 3 , A 5 , A 7 , A 9 ) and the errors for each equated sample are approximated and embedded in lower significant bits (62) of samples (A 0 ", A 1 ", A 2 ", A 3 ", A 4 ", A 5 ", A 6 ", A 7 ", A 8 ", A 9 ") of the second digital data set (61).
