Abstract

PURPOSE: To obtain position information, by which relative positions of a pickup means and a recording medium are automatically changed accurately and easily, and make it possible to display a playing time on a basis of this information.
CONSTITUTION: Line number code 21 is superposed with digital signals between proper horizontal synchronizing pulses HP in a vettical flyback time. This line number code is extracted by line signl extracting circuit 31, and the code number is displayed on display part 33 and is applied to comparator circuit 34. Comparator 34 is provided with code input end 35 from the external, and code is set previously; and if this set code agrees with the line number code from circuit 31, a coincidence pulse is applied to access circuit 37 to execute information processings for device control.
