| Abstract: |
A system, apparatus and method for interactively controlling the rate of real-time video playback and audio track playback is disclosed. A preferred embodiment of the apparatus is an interactive exercise video system which utilizes a bicycle, a bicycle wheel speed detector, an interface unit connected to the wheel speed detector and to a conventional game controller connected to a conventional video game CD player, which is in turn connected to a TV. A prerecorded video CD is played in the player in which the display rate of video images is altered via software embedded on the CD such that the speed of the video is changed by the level of activity on the exercise device. The variation of the video frame rate is accomplished by modifying the duration time stamp on each video frame which is used by the player control program so as to change the sequential time at which each frame is called for display by the conventional video player. The variation of video display rate is independent of the pitch of the audio play rate. To maintain synchronization of the audio with the video without changing the pitch of the audio, portions of the audio are looped back, i.e. replayed.

What is claimed is:
1. An exercise monitoring apparatus for use in conjunction with an exercise device operated by a user which has an exercise rate detector thereon producing a signal representative of an actual exercise rate by said user, said apparatus comprising in combination:
- a video playing device having a central processing unit and a remote user input control pad connected thereto for receiving input from said user and transmitting said input to said central processing unit;
- a prerecorded video frame sequence encoded on a storage medium playable on said playing device;
- a video monitor connected to said playing device for displaying said prerecorded video frame sequence reproduced by said playing device; and
- a means operable in said playing device for varying the rate of display of sequential frames in said video frame sequence reproduced by said video playing device on said monitor in response to said signal from said rate detector of the actual rate of exercise by said user wherein each of said recorded frames includes a frame time stamp and said program includes a means for generating a variable time adjustment factor in proportion to said exercise rate signal and a means for applying said factor to said frame time stamp to determine a modified time at which the next video frame in said sequence is to be displayed.
