Abstract
The invention concerns a method and apparatus for audio program playback during fast forward playback video trick modes. A storage medium reader can be configured to read coded digital data from a storage medium such as a DVD. The coded digital data can be a video presentation having correspondingly formatted video and audio frames. An audio processor can insert silence frames in a selected block of the audio frames and portions of the audio frames can be deleted to compensate for video trick mode playback. Resulting audio frames can be concatenated to create 1× audio for various video trick modes playback.
