AUDIO WATERMARKING TECHNIQUE FOR MOTION PICTURE PRESENTATIONS |
摘要 |
Audio watermarking of a motion picture film containing a DTS(R) sound track occurs by selectively deleting one or more identifiers that appear within the synchronizing codes in the sound track. Upon screening of the film by a projector a DTS(R) reader will send information to a DTS(R) CD player which can detect the absence of the identifier and generate the audio watermark accordingly. |
