A multiple picture image manipulation system for receiving video information related to a plurality of pictures. A designation control designates the output priority order of the respective pictures. A priority coder detects picture information having the higher priority present for producing a control signal indicating this detected priority, and a selector controlled by this signal outputs information from the plurality of pictures so as to select from only a single picture designated with the higher priority present where picture overlap occurs to provide a multiple picture image in which one of said pictures masks another without overlap degradation when displayed. Additional facilities for cross-fading following a change in the picture priority may also be included which pictures can have an associated border if desired.
