ABSTRACT:
A multiple picture/sound signals decoding apparatus having a reduced-scale structure and capable of reproducing multiple moving pictures simultaneously on a single display device. For decoding input signals such as multiple moving picture signals and sound signals read out from a recording medium or those received via transmission lines, the apparatus includes at least one decoder for curtailing the input picture signals at a predetermined interval to produce multiple picture signals reduced both horizontally and vertically, and decoding each of such multiple picture signals; frame memories connected to at least one decoder; a display for displaying the multiple pictures simultaneously on a single screen; and a controller for controlling the operations of the one or more decoders and the display. In response to a mode selection signal, the controller selects a multiple moving picture mode for displaying the reduced multiple moving pictures simultaneously on a single screen of the display means, or a single moving picture mode for displaying merely one of the multiple moving pictures on the screen of the display.
