Abstract

AN INTEGRATED DIGITAL VIDEO SYSTEM IS CONFIGURATED TO IMPLEMENT PICTURE-IN-PICTURE MERGING OF VIDEO SIGNALS (101, 104) FROM TWO OR MORE VIDEO SOURCES, AS WELL AS SELECTIVE OVERLAYING OF ON-SCREEN DISPLAY (OSD) GRAPHICS ONTO THE RESULTANT MERGED SIGNAL. THE PICTURE-IN-PICTURE SIGNAL IS PRODUCED FOR DISPLAY BY A TELEVISION SYSTEM OTHERWISE LACKING PICTURE-IN-PICTURE CAPABILITY. THE DIGITAL VIDEO SYSTEM CAN BE IMPLEMENTED, FOR EXAMPLE, AS AN INTEGRATED DECODE SYSTEM (40, 100) WITHIN A DIGITAL VIDEO SET-TOP BOX OR A DIGITAL VIDEO DISC PLAYER.IN ONE IMPLEMENTATION, A DECOMPRESSED DIGITAL VIDEO SIGNAL IS DOWNSCALED AND MERGED WITH AN UNCOMPRESSED VIDEO SIGNAL TO PRODUCE THE MULTI-SCREEN DISPLAY. THE UNCOMPRESSED VIDEO SIGNAL CAN COMPRISE EITHER ANALOG OR DIGITAL VIDEO. OSD GRAPHICS CAN BE COMBINED WITHIN THE INTEGRATED SYSTEM WITH THE RESULTANT MULTI-SCREEN DISPLAY OR ONLY WITH A RECEIVED UNCOMPRESSED ANALOG VIDEO SIGNAL.(FIG. 4)
