TH92932A - Techniques for printing sound watermarks for film set releases. - Google Patents

Abstract

DC60 Printing of sound watermarks onto film films (10) containing DTS Reistered Trademark (12) soundtracks is achieved by selecting erase identifiers that appear within the tempo code in one or more soundtrack, provided that when The film is projected by a projector (102). The DTS Reistered Trademark (104) reader transmits information to a DTS Reistered Trademark (106) CD player capable of detecting an identifier missing and generating an audio watermark. Under that condition, the printing of an acoustic watermark onto the film (10) containing the DTS (formula) (12) soundtrack is performed by selecting Remove the identifier appearing within the timing code in one or more tracks. Provided that when the film is projected by the projector (102), the DTS (formula) reader (104) transmits information to a DTS CD player (formula) (106) capable of detecting the identifier missing and Sound watermark can be created according to that condition.
