1. An exercise system comprising:
- a video playing device in communication with a central processing unit and a user input interface connected thereto adapted and configured to receive one or more inputs from a user and transmit the one or more inputs to the central processing unit;
a video frame sequence encoded onto a storage medium in communication with and playable on the video playing device;
a video monitor in communication with the video playing device for displaying the video frame sequence reproduced by the video playing device;
a video frame rate controller configured to vary a rate of display of sequential frames in the video frame sequence reproduced by the video playing device on the video monitor in response to the one or more inputs from the user;
one or more audio rate controllers configured to vary a rate of delivery of two or more audio files on an audio playing device in response to the one or more inputs from the user; and
an exercise device.

Abstract
Disclosed are systems and methods for detecting the movements in an exerciser'"'"'s repetitive movement pattern that, when pre-recorded audio footfall sound files are played, most closely support the illusion that the user is generating the sounds with their own “virtual” footfalls, thus creating an enhanced virtual exercise experience. The system generates a signal to communicate the virtual footfall timing with a media playback system, and plays back media files that support the virtual exercise experience.

- 13. The system of claim 1 wherein each of the recorded video frame sequences includes a frame time stamp and the video frame rate controller is adapted to generate a variable time adjustment factor in proportion to the one or more inputs from the user and a adjustor adapted to apply a factor to the frame time stamp to determine a modified time at which the next video frame sequence is to be displayed.

13-1. An apparatus for engaging a user of an exercise device interactively in viewing a video frame sequence of an activity on a video monitor comprising:
-
a video player in communication with the video monitor adapted and configured to play a video frame sequence on the video monitor; a detector adapted and configured to detect a rate of exercise by the user on the exercise apparatus and transmit a signal proportional to the rate of exercise; a video controller in communication with the video player adapted and configured to receive the signal proportional to the rate of exercise and transmit a signal generated in response to the signal proportional to the rate of exercise to the video player wherein the video player adjusts the rate at which the video frame sequence is displayed; two or more audio controllers in communication with an audio player adapted and configured to receive the signal proportional to the rate of exercise and transmit one or more signals generated in response to the signal proportional to the rate of exercise to the audio player wherein the audio player adjusts the rate at which the audio is played.

17. A method of controlling a video frame sequence display rate of a video playback sequence in a device in response to an external signal comprising the steps of:
-
(a) accessing a duration time stamp for a current video frame; (b) determining from the external signal an adjustment value for changing the display rate (c) obtaining a modified duration time to a next frame by adding the adjustment value to the duration time stamp; (d) displaying the next frame when the modified duration time has passed; (e) accessing a duration time stamp for a current audio data packet; (f) determining from the external signal an adjustment value for changing the rate of delivery of the audio data packet; (g) obtaining a modified duration time to a next audio frame by adding the adjustment value to the duration time stamp; and (h) playing the next audio data packet when the modified duration time has passed. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
