Abstract
The invention relates to a software method for reducing the electromagnetic irradiation of the Phase Lock Loop (PLL) within an On-Screen Display Menu system. The method includes the steps as follows: setting the resolution of an OSD system to a predetermined pass value of Electromagnetic Interference (EMI); checking the OSD system; changing the resolution of the OSD system to a value to be displayed if the OSD system is started; keeping on the predetermined value of EMI if the OSD system is not started; repeating the checking of the OSD system step.
