ABSTRACT:
The invention concerns a method and apparatus for audio track playback during fast forward playback video trick modes. A storage medium reader is provided for reading digital data from a storage medium such as a DVD. The digital data represents a video presentation 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 presentation. Subsequently, a digital signal processor can convert the audio samples to their corresponding frequency domain equivalents and scale the frequency and amplitude of a playback audio frequency associated with the audio samples in accordance with trick mode video playback.
