generate an output video stream. This improves the overlay picture quality when the external FSO and
digital RGB signals are generated by an asynchronous source.
SCART 4x oversampled fast switching between component RGB input and CBVS input
The SCART overlay control signal (FSS) is oversampled at 4x the pixel clock frequency. The phase of
this signal is used to mix between the CVBS input and the analog RGB inputs. This improves the
analog overlay picture quality when the external FSS and analog video signals are generated by an
asynchronous source.
