    I want to make a device that will take in live video add some text and
    output it with the text,

    the text will be Line 1 and Line 2 and i want it to change using the
    parallel port so when i make pin2 high it will add Line 1 and when i
    make pin3 high it will add Line 2 to the live video,

    i read somewhere about using a PIC and LM1881 sync seperator but i
    really wouldnt know where to start and wondered if there was a site
    with a guide or something. Thanks
  2. You might want to look at this then:

  3. Point your favorite search engine towards OSD, or "On Screen Display"
    chips. There are a number of them available, and if this is for a
    personal project you can probably pull the chip and support circuits
    from a newer SVGA monitor that has other problems.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.
