Aspect correction
Horizontal direction compression or expansion is effected by changing the PLL oscillator frequency. There are
limitations on the values of this setting, so be sure to refer to the separate “APPLICATION NOTE” document for
details.
<Application Example>
— When multi-mode is used
— 16:9 aspect ratio tube
Fine adjustment of setting values
This function allows the number of external components (such as delay circuits) to be reduced.
— Position of the image within the sub-screen
— Display position
— Clamp pulse position
— Phase difference between the Y and R-Y/B-Y D/A converter outputs
