Method and arrangement for encoding or decoding a sequence of digital data

Abstract

A method is provided for encoding and decoding a sequence of digital data, according to which a portion of the sequence of digital data corresponds to a data block that includes several data packets, at least two data packets per data block containing an identifier. The position of the data packet within the corresponding data block can be determined based on the identifier, and the data is encoded or decoded by taking into account the identifier.
