ABSTRACT:
A video receiver for SCART input includes an input configured to receive a composite video signal, RGB signals, and a switch-indicating signal, a first digitizer module coupled to the input and including a one-bit slicer configured to receive and convert the switch-indicating signal to a one-bit digital signal, the first digitizer further including a downconverter configured to convert the one-bit signal to a multi-bit digital signal with non-abrupt transitions between a logical zero and a logical one, and a combiner module configured to receive and combine indicia of the composite video signal and the RGB signals to produce a total video output signal as a function of the indicia of the multi-bit digital signal.
