7.12. SCALER TAB
The 7814 series of converters utilize high performance multi-tap polyphase filters to perform scaling and
aspect ratio conversion on the input signal. The Scaler control menus are used to configure the cut-off
frequencies of the polyphase filters and to define the aspect ratio conversion. In addition, the Scaler tab
contains specific controls for managing sharp vertical and horizontal edge transitions so that edge ringing
is minimized. Static side panel colours and output AFD stamping values are also adjusted within this tab.
Sections 7.12.1 to 7.12.5 provide detailed information about each menu item.
