Abstract

PURPOSE: To realize a double-screen television picture receiver with a low cost by using one unit of the 1-field memory plus two units of the 1-line memory each and thus reducing the number of the 1-field memory from two to one.
CONSTITUTION: Writing control part 17 designates the address of main memory circuit 31 consisting of one unit of the 1-field memory, and the video signals of the secondary channel are sampled in sequence to be written into circuit 31. Transfer control part 22 designates sequentially the addresses of circuit 31, and the video signals of the secondary channel are read out by the amount equivalent to one line to be transferred alternately to each memory of auxiliary memory circuit 32 which incorporates two memories I and II possessing the memory capacity equivalent to one line each. The video signals memorized in memories I and II are read out in sequence and by the amount equivalent to one line through reading control part 27 and in the display period of the secondary channel to be sent to the video mixer circuit.
