摘要
In a method and device for encoding and/or decoding a sequence of discrete source values (Si) sub-groups (Gi) of a number of successive source values are taken from the sequence of source values. The sub-groups of source values are encoded into packets, comprising in each case an initial value (S1) corresponding to a first source value in a sub-group, a standardization factor (R) and difference values (DeltaSi), standardized in accordance with the standardization factor, between values corresponding with other source values (Si) in the sub-group and in each case a value corresponding with a preceding source value (Si-1) in the sub-group. A standardization factor (R) is determined per packet subject to a greatest difference value (Deltamax) within the sub-group between a source value and a preceding source value. The invention also relates to an information carrier provided with a thus encoded sequence of source values.
