Abstract
An apparatus and corresponding method for reducing and displaying N input video scenes within a larger, selected main video scene. A main picture signal is selected from the N input picture signals. The N input signals are then selected sequentially by a counter to be auxiliary picture signals that are stored in respective areas of a digital memory. By switching the output signal between the main picture scene signal and the auxiliary picture scene signals from memory, the auxiliary picture scenes may be displayed at predetermined locations within the main picture scene. Additionally, one of the N input video signals may be from video tape recorder having an input provided by any of the remaining N-1 input video signals. Proper recording by the video tape recorder may then be monitored as one of the N auxiliary picture scenes.
