Abstract

PURPOSE:To previously see a state with a superimposed caption, thereafter see the state with no superimposed caption by providing a means for detecting the superimposed caption and erasing the superimposed caption. CONSTITUTION:When a switch 3 turned ON, a detecting means 1 operates to erase the superimposed caption by an erasing circuit 2 and a video having superimposed caption is outputted on the screen of a television 5 connected to a video deck 4. When it is desired to erase the superimposed caption, it can be erased simply by the operation of a switch and when it is desired to input the superimposed caption again after the superimposed caption is erased once, the switching operation is cancelled and then the superimposed caption can be inputted.
