CONFIGURING THE SCALER

The 7711HDC scaler chip uses a process of filtering in order to reduce the resolution from 1920 x 1080 (or
1280 x 720) to 720 x 480 (or 720 x 576). The Scaler menus are used to configure the cut-off frequencies
of the filters associated with the scaler hardware. The chart below shows the items available in the Scaler
menu. Sections 6.6.1 to 6.6.2 give detailed information about each of the menu items.
