Abstract:
1. A method of creating synchronisation information for synchronising a multimedia content file with an associated text file, the method including the steps of: subdividing the text file into one or more samples, each sample including zero or more consecutive characters of the text file, wherein each sample is associated with a corresponding contiguous time interval of the multimedia content file; calculating, for each sample, a corresponding consumption rate value, which is a ratio between a total number of characters of the sample and a duration of the associated contiguous time interval of the multimedia content file; and storing the calculated consumption rate values within a series of one or more synchronisation data records in a file or database separate from the multimedia content file and the associated text file, each record additionally comprising one or more of: a start character offset; a multimedia content file cue time; and an interlude length, whereby content of one or more of the synchronisation data records may subsequently be used to compute a time position within the multimedia content file which is proximate to any one or more corresponding text characters defined by a character offset within the associated text file.
