Claim One:
1. Apparatus for producing data in a virtual set memory representing a composite image from a combination of a virtual image and a camera field of view image, the apparatus comprising: a plurality of cameras, each disposed for capturing data representing a respective field of view and each having a frame buffer associated therewith for receiving and storing data representing virtual images, for subsequent selective retrieval; a virtual image data source for generating data representing virtual images and for supplying such data to the frame buffer associated with a broadcast camera configured for moving spatially, wherein the last image drawn by the image generator is stored in the frame buffer when the broadcast camera stops moving and then virtual image is supplied to another single movable camera; and a means for compositing data representing the field of view of a selected one of the plurality of cameras and data representing a virtual image retrieved from a frame buffer associated with the selected one of the plurality of cameras, to produce data in the virtual set memory.
