Method and apparatus for synchronization of ancillary information in film conversion

A digital processor to synchronize ancillary information with film images during a film conversion session, the digital processor comprising:

• means for converting the ancillary information in the form of analog signals to digital signals and frequency shifting the digital signals to achieve a selected data rate that matches rate of film conversion;
• means for adjusting data rates of the ancillary information in the form of digital signals to achieve the selected data rate;
• means for decoding the ancillary information in the form of encoded data and re-encoding the data to achieve the selected data rate;
• and
• means for formatting the ancillary information at the selected data rate and combining the formatted ancillary information with the film images in a standard motion picture format.

A method of synchronizing audio with film images during a film conversion session, the method comprising:

• converting analog input signals to digital signals;
• buffering the digital signals for subsequent processing;
• frequency shifting the digital signals to achieve a selected data rate to match a film conversion rate;
• formatting the digital signals at the selected data rate to produce a digital audio file conforming to a standard audio format;
• and
• combining the digital audio file with digital film images conforming to a standard motion picture format.
