Abstract
A stream of channel bits, of a signal relating to a binary channel, is decoded into a stream of source bits, of a signal relating to a binary source. This binary channel includes a main channel and a secondary channel. This secondary channel is embedded in the main channel. Errors in the stream of secondary channel bits are corrected using a stream of corrected main channel bits. This stream of corrected main channel bits is reconstructed from a stream of corrected source bits. The secondary channel can be embedded in the main channel in different manners, e.g. via multi-level coding or via merging-bit coding.
