Informed Decoding in an Address Format

When a jump is made while reading from an (optical) disc, prior information about the address on the landing position is known. When the address information is protected by a systematic Reed Solomon error correcting code, this prior information does not give an increased error correction capacity. If, however, informed decoding Reed Solomon encoding is used, the information does give an increased error correction capacity. Only some simple post processing has to be added to the decoding path in that case. One can benefit from this encoding method with a simple check after decoding.
