Abstract
Abstract A method of recording a real-time multimedia presentation and replaying a missed portion at an accelerated rate until the missed portion catches up to the current point in the presentation. The multimedia presentation may consist of audio, video, graphics, and text. A graphical timeline is provided to allow the user easy access to different points in the recorded presentation. All the media formats are synchronized at the accelerated rate and the audio is accelerated without changing its pitch.
