ABSTRACT:
The signals received by tuners are processed respectively by video processing circuits and fed to a synthesizing circuit by way of compression circuits so that the images of the signals are displayed respectively on left and right side sections of the screen of a display unit. The characters and graphics from a teletext/data transmission decoder are synthetically combined with the portions of the images of the video signals for blank zones of the screen by the synthesizing circuit. The characters and graphics transmitted through a data channel are displayed clearly to the viewer by an ingenious technique devised for displaying characters and graphics of a supplementary program.
