METHOD FOR CHANNEL DECODING A DATA STREAM CONTAINING USEFUL DATA AND REDUNDANT DATA, DEVICE FOR CHANNEL DECODING, COMPUTER-READABLE STORAGE MEDIUM AND COMPUTER PROGRAM ELEMENT

摘要

A method is provided for channel decoding a data stream containing useful data and redundant data, the data stream exhibiting at least one known source-coded errored bit sequence which identifies a pre-determined position within the data stream, wherein the data stream is channel decoded, the source-coded errored bit sequence is determined from the channel-decoded data stream, and the data stream is again channel decoded taking into consideration the detected source-coded errored bit sequence.
