US Patent 7889969 Audio frequency shifting during video trick modes

The invention concerns a method and apparatus for audio content playback during fast forward playback video trick modes. A storage medium reader is provided for reading coded digital data from a storage medium such as a DVD. The coded digital data comprises a video programming and a corresponding audio programming. A decoder decodes from a portion of the digital data comprising the audio programming a plurality of digital audio samples corresponding to a selected portion of the video programming. Subsequently, an audio processor key shifts a playback audio pitch associated with the audio samples to compensate for the higher pitched audio associated with the fast forward video playback mode.
