Preliminary specification

Multistandard Picture-In-Picture (PIP)

controller

SAB9079HS

In this application there is no relationship between the deflection and acquisition circuits. A double window feature can

be realized by letting the feature box compress one window and make the second window by the SAB9079HS. In this

application the HVSYNC of the feature box/line doubler is connected to the main acquisition HVSYNC. The restriction is

that no main PIPs can be displayed. The application diagram is illustrated in Fig.10.
