Apparatus for use with standard television (TV) for superimposing images, captions, titles, or other information over the television scene. Synchronization of the superimposed images with the television scene is brought about by phase locking the images to the horizontal synchronization pulse train of the television scene. A joystick input device allows the television viewer to select from a library of superimposed images and to move the images to any location over the television scene. The viewer may continue to move the superimposed images over the television scene to set up and maintain humorous or other expressive effects. The apparatus can also be used as an educational tool in conjunction with appropriate broadcasted or recorded programming. Closed-graphics information received with a television signal may generate and control locally generated graphic overlay images to provide interactive gaming or educations applications. The horizontal synchronization pulse train of the television scene can be modified by introducing variable time delays from one pulse to the next. This variable synchronization delay can be used to create fun-house mirror effects. |

DETAILED DESCRIPTION I claim: 1.
An interactive television graphics apparatus comprising: video input means for receiving a background video signal, said background video signal including at least one graphics control signal for performing one or more of the following functions: selecting a locally generated graphic image overlay component, positioning a graphic image overlay component, and defining a bit map of a graphic image overlay component; memory means for storing at least one graphic image overlay component, including one or more of: a locally generated graphic image overlay component, and a bit map of a graphic image overlay component received from said video input means; and processor means, coupled to said video input means and said memory means for receiving said graphics control signals and generating a graphic image as an overlay over said background video in response to received graphics control signals, wherein said graphics control signals comprise signals for selecting a graphic image stored in said display means.
2.
The interactive television graphics apparatus of claim 1, further comprising: a user input means, coupled to said processor means, for generating user graphics control signals in response to a user input, wherein said processor means receives said user graphics control signals and generates a graphic image as an overlay over said background video in response to received locally generated graphics control signals.
3.
The interactive television graphics apparatus of claim 1 wherein said graphics control signals comprise signals for selectively positioning a graphic image stored in said memory means.
4.
The interactive television graphics apparatus of claim 2 further comprising: synchronization means, coupled to said video input means, for generating synchronization signals from said background video signal; address generator means, coupled to said memory means, said processor means and said synchronization means for selectively generating memory addresses for said memory means in response to said processor means and in synchronization with said synchronization means; and video output means, coupled to said memory means, for selectively reading graphic image data from said memory means in synchronization with said synchronization means and merging said graphic image with said background video image
