Abstract

PURPOSE: To secure an easy DC reproduction of the reading signal as well as to increase the using efficiency of the memory element by securing the simultaneous projection for the pictures of the main and secondary channels onto the screen of a TV picture receiver.
CONSTITUTION: The pedestal level information of the horizontal synchronous signal rear edge part is written along with the video signals on the secondary channel into memory device 20 via counter 26, setters 29 and 30 plus comparators 27 and 28. And the secondary channel TV signals read out of device 20 are clamped 22 at the fixed DC level based on the pedestal level information. Then the pedestal level information is removed 16 from the secondary channel TV signal which is clamped 22 to carry out the DC reproduction for the video signals of the secondary channel. In such way, the DC reproduction of the reading signal can be facilitated, also increasing the using efficiency of the memory element.
