Claims
- 1. An apparatus for interacting with a TV, comprising:
- means for generating a disruption signal representative of an image to be superimposed over a portion of a scene displayed on the TV, the scene being derived from a video signal received by an antenna input of the TV from a source, the disruption signal generating means including an RF oscillator having a bandwidth that covers substantially all of a VHF band and a UHF band;
- means for coupling the disruption signal generating means to the antenna input of the TV;
- means for synchronizing the disruption signal with the video signal to produce a synchronized disruption signal;
- means for adjusting the amount of delay of the synchronized disruption signal to thereby determine a vertical position and a horizontal position on the scene where the image will be superimposed; and
- means for manually controlling the adjustable delay means for allowing a viewer to cause the superimposed image to appear over the selected portion of the scene at a selected time.
- 2. An apparatus according to claim 1 wherein the synchronizing means includes a locked oscillator.
- 3. An apparatus according to claim 1 and further comprising means for simultaneously generating a selected sound effect each time the viewer causes the superimposed image to appear over the selected portion of the scene.
- 4. An apparatus according to claim 1 wherein the superimposed image has the general appearance of an explosion.
- 5. An apparatus for interacting with a TV, comprising:
- means for generating a disruption signal representative of an image to be superimposed over a portion of a scene displayed on the TV, the scene being derived from a video signal received by an antenna input of the TV from a source;
- means for coupling the disruption signal generating means to the antenna input of the TV;
- means for synchronizing the disruption signal with the video signal to produce a synchronized disruption signal, including an oscillator locked to a horizontal sweep EMI signal generating during a flyback portion of a raster scan of the TV;
- means for adjusting the amount of delay of the synchronized disruption signal to thereby determine a vertical position and a horizontal position on the scene where the image will be superimposed; and
- means for manually controlling the adjustable delay means for allowing a viewer to cause a superimposed image to appear over the selected portion of the scene at a selected time.
