    I've got one question: The TDA 3562A (datasheet available at: provides, as far as I
    can understand, principal two inputs:
    1st: Luminance/Chrominance (SVHS)
    2nd: R G B external inputs

    How can I switch between these two inputs? Or uses TDA 3562A both inputs and
    will handle it together and will provide "a sum" off at the R G B output

    Has anyone an idea?

    Thank you very much!!

    AFAICS, the RGB inputs could be used for an OSD and would be
    enabled/disabled by the Data Blanking Input at pin 9.
