A storage medium carries symbols representing digital information encoded in two dimensions. A method and apparatus recovers the symbols using oversampling in two dimensions and derives the information represented by the symbols. In one embodiment, the symbols are carried on motion picture film between the sprocket holes.

Selecting analog or digital motion picture sound tracks

A storage medium carries physically distinct blocks of symbols representing digital information. The symbols are arranged in the blocks such that the digital information represented by the symbols can be determined from only the two-dimensional position of the symbols relative to one another and any other differentiable characteristic intrinsic to the symbols. A method and apparatus recovers the symbols using oversampling in two dimensions and derives the information represented by the symbols. Blocks having two or more two-dimensional alignment patterns with good auto-correlation properties are used in some embodiments to facilitate recovery of the digital information. In one embodiment, motion picture film carries a conventional analog soundtrack and a digital soundtrack for a plurality of channels; the digital soundtrack is represented by symbols carried on the film in the areas between sprocket hole perforations.

Storage medium for carrying information encoded in two dimensions

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.

Apparatus using one optical sensor to recover audio information from

An apparatus and method receive and process information, and adapt the operational characteristics of the processing in response to material included in the received information. More particularly, the apparatus and method embody a software-controlled process which adapts or modifies the software in response to the received information. One embodiment is described in connection with a motion picture film which carries a conventional analog SVA soundtrack and a digital soundtrack with a digital representation of software required to properly process the digital soundtrack. An apparatus and a method according to one embodiment establishes what version of software is required to properly process the digital soundtrack, optionally modifies its software from information carried with the digital soundtrack if the current version on hand is not adequate and uses the updated version of software to process the digital soundtrack on the remainder of the current film and other future films until such time as another software update is required.

Storage medium and apparatus and method for recovering information from

The invention relates generally to an apparatus and a method for receiving and processing information, and for adapting the operational characteristics of the processing in response to material included in the received information. More particularly, the invention relates to an apparatus and a method embodying a software-controlled process which adapts or modifies the software in response to the received information. Although the invention has many applications, the invention is more particularly described in connection with a motion picture application in which film stock carries a conventional analog SVA soundtrack and a digital soundtrack with a digital representation of the software required to properly process the digital soundtrack. An apparatus and a method according to one embodiment establishes what version of software is required to properly process the digital soundtrack, optionally modifies its software from information carried with the digital soundtrack if the current version on hand is not appropriate, and uses the updated version of software to process the digital soundtrack on the remainder of the current film and other future films until such time as another software update is required.
