Maximum likelihood encoding apparatus, maximum likelihood encoding method, program and reproduction apparatus

摘要

A maximum likelihood encoding apparatus is provided, which is constructed to be compatible with a plurality of signals reproduced from a plurality of recording media having a plurality of types. The apparatus comprises a path metric value generation section for generating a plurality of path metric values corresponding to a recording medium having one of the plurality of types based on a type signal indicating the one of the plurality of types, and a path memory section for detecting digital information from a signal reproduced from the recording medium having the one of the plurality of types based on the plurality of path metric values.
