A method is provided for reliably receiving digital information from a transmitting device. The information to be received is arranged in discrete subunits (201, 202, 203, 204, 301, 302, 303, 304) so that a predetermined number of subunits correspond to a superunit (200, 300). It is encoded with a certain error detection code (402), corresponding to a certain error detection decoding method, and additionally with a certain error correction code (403), corresponding to a certain error correction decoding method. According to the invention a superunit is error correction decoded (405), and during the error correction decoding (405), the decoding reliability of each subunit of the superunit to be decoded is separately estimated. The error correction decoded superunit is error detection decoded (406), and during the error detection decoding it is detected, whether or not there were errors in the superunit to be decoded. Partial corrective action (407, 408, 409, 450, 451) is arranged for on the decoded superunit on the basis of the estimated reliabilities of the subunits.
