Abstract

Very large compression ratios are obtained by compressing a digital file in a temporal or 'time-based' manner. In a preferred embodiment, a compressed version of the file is a representation of the amount of time required to process the digital file (102) against a given function (110). As the digital file is processed against the given function, a count (e.g. timer) is incremented at a given rate (106). The size of the file determines how long the file will take to be processed by the given function. When the processing is complete, a value of the timer is then converted into a representation of the file (112). The digital file is later reconstructed from the representation by applying an inverse of the given function.
