NVIDIA VIVO + CUDA

Are there any cards supporting some kind of video in (VIVO, tv out with wdm drivers) that will allow frames to be written to the card subsequently processed with CUDA?
I would like to take the host almost entirely out of the equation and move data from input buffers to output buffers completely on the device.

  • Right now I see wdm drivers for video in supporting geforce 6 and 7 series cards, but not 8 (cuda capable)
  • I’m not really familiar with the video in capability of existing cards, but I am pretty much only seeing older cards with VIVO listed
  • Some newer cards list the tv-out, but it is unclear whether this is the same VIVO capability that supports video in

Has anyone successfully done this?
Is nvidia even doing video in at all now?
