Abstract
A television system is provided wherein a target region in successive video images is replaced by a matching pattern adapted to be inserted into the target region, using a virtual insertion unit located downstream of the originating site. The system includes television cameras for, when active, producing a sequence of video images of a scene, and a switcher or multiplexer for switching between camera images. A broadcast image processor located with the multiplexer in an outside broadcast van receives the video images and adds layers of graphics and special effects to the video images to produce a broadcast feed. The virtual insertion unit, which is located off-site from the van, receives the broadcast feed and modifies the video images of the broadcast feed by replacing the target region of these images with a replacement pattern adapted to be inserted into the target region.
