Abstract

PURPOSE: To make suitable the unit in the processing at the digital integrated circuit, by making unnecessary the analog processing through the drawing of the pattern on the screen controlled with the digital code corresponding to the reception frequency.
CONSTITUTION: The reference counter 17 counts the clock pulse CL in synchronizing with the horizontal synchronizing signal H. The content of the presettable counter in which the channel selection code of electron tuner is stored in the register 18. The content of the register 18 and that of the reference content of the register 18 and that of the reference counter 17 are compared at the pulse generator 19 to form the pulse P in which the pulse width is changed according to the content of the register 18. The bar pattern is obtained on the screen by processing the pulse at the vertical position set circuit and superimposing it on the video circuit. Since no analog processing is required in this unit and digital processing is entirely enabled, it is suited to the display integrated circuit.
