    Has anyone modified or think it possible to use a USB webcam and
    modify it so as to input a baseband composite video signal straight
    into it via a cable instead the camera part? Basically it would be a
    composite video signal convertor to USB input to a pc.

    Two different animals. VGA digital and NTSC or PAL analog standards

    There are PCI boards for the purpose. You need to search for them.
    They sell a TV tuner that is roughly the size of a USB flash drive for
    ~$30 that will turn the computer into a TV and also video monitor
    (what you want). Lots of PCI cards on the market too with all sorts
    of added features for very low cost.

    Google is your friend - next time post your question to an
    appropriate group

    The sensor in a WebCam type of device has a serial interface (SPI)

    That serial interface is sent to the PC via its driver to make an mpeg file.

    So its three different animals. ;-)
