Abstract

PURPOSE:To project picture information of plural channels simultaneously in one screen with tuners whose number is smaller than the number of projected pictures, by storing video information after using a ring counter to select plural channels successively at a fixed period. CONSTITUTION:Channel selecting means 18 which selects plural channels successively at a fixed period, means 22 which writes and stores obtained video information of plural channels individually, and means 20 which reads out successively plural stored video information correspondingly to prescribed positions of the screen are provided. Then, a ring counter driven by clock pulses is used as channel selecting means 18 to write and store video information plural channels obtained by selection successively into memory elements individually, and video information are read out successively correspondingly to prescribed positions of the screen in a high speed, thus projecting pictures of plural channels simultaneously.
