Abstract

A method for encoding a sequence of integers includes identifying a contiguous sub-sequence in the sequence of integers wherein the sub-sequence includes interrelated integers having a same prefix when being variable length encoded and an independent last integer. A code for the contiguous sub-sequence is formed using a code for an indication of the number of interrelated integers in the contiguous subsequence, a code of a prefix indication, and the suffixes of variable length codes of the integers in the contiguous sub-sequence. In doing so, a single prefix is sufficient instead of n individual prefixes.
