Abstract
PURPOSE: To enable to display the display almost equal to the ratio of aspect with a simple configuration to any systems, by memorizing the video signal once in the buffer memory and by transferring the video signal in a given order to the common main memory based on the discriminated output and the program designation input.
CONSTITUTION: The reception circuit 1 receives the TV signal in which one of the still picture signals of a plurality of systems at least is multiplexed at the H period during the vertical blanking period, and the buffer memory 4 can memorize the video signal at H period for any systems. Further, the buffer memory 5 has a memory capacity which can memorize all the video signals in the still picture to be displayed, and it discriminates the type of system for the still picture received with the type discrimination circuit 12. Moreover, the frequency of the display clock pulse for the memory 5 is selected depending on the output of the circuit 12 and selection can be made so that almost equal aspect ratio can be displayed even to the still picture of any systems. Thus, the display easy to see and having aomost equal aspect ratio can be made to the reception of any systems.
