ABSTRACT:
An apparatus recovers audio information from analog and digital motion picture film soundtracks using a single optical sensor that senses across the widths of both soundtracks. Symbols representing audio information in the digital soundtrack are encoded in two dimensions and are recovered by oversampling the symbols in two dimensions. The two-dimensional encoding of digital information can be used with a variety of recording media; however, in one embodiment, the symbols are carried on motion picture film between the sprocket holes.
