Abstract
Apparatus, system and method for encoding and decoding ancillary code for digital audio, where multiple encoding layers are merged. The merging allows a greater number of ancillary codes to be embedded into the encoding space, and further introduces efficiencies in the encoding process. Utilizing certain error correction techniques, the decoding of ancillary code may be improved and made more reliable.
