Abstract
Video images derived from a video recording medium (such as a video disc or tape) using a video playback unit are displayed on the screen of a cathode ray tube display simultaneously with video images generated from a microprocessor-controlled video game. The video game permits a user to manually control the position of some of the generated video images displayed. Signals in the horizontal interval portion of each field from the video playback unit are related to the video images in the pictorial portion of each such field and identify certain characteristics of the video images such as the location of the video images. This information is used in such a manner that the video images from the video playback unit can interact with the video images from the video game.
