ABSTRACT:
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.
