Viji, The video capture card will be the device that you connect your image source to and that is responsible for acquiring the image that you want. Unfortunately National Instruments does not develop any image acquisition device that will acquire from a basic RC jack. We do have a board that will acquire images from an S-Video connection, so some customers can acquire images from high-end, commercial VCRs to our image acquisition board through an S-Video connection.
Also, currently our IMAQ and Vision products are only supported and developed on the Windows platform, and we do not have IMAQ/Vision support for Linux. Because of this, you will not be able to use the IMAQ or Vision functions on a Linus machine, unless you can find or create a 3rd party driver that interfaces properly.
