The 7812UDXD 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 6.12.1.1 to 6.12.5.2 provide detailed information about each menu items.
