The VideoLogic DVA-4000 allowed you to display full-motion video or still frames overlayed onto standard PC graphics. It was available in ISA and MCA variants. It consisted of three cards:

  • The VideoLogic MediaSpace, a full-length ISA card. This can take a video signal in several different formats (S-VHS, VGA, etc.) and compress it into an MJPEG video stream. The encoding was performed by a CL550 JPEG chip under the control of an Inmos T400 Transputer chip. This card was capable of encoding video a quarter the resolution of the screen at 25 frames per second.
  • The VideoLogic DVA-4000 motion video board, a full-length ISA card. This is capable of capturing 24-bit-per-pixel images from either the two external VGA inputs, the internal VGA feature connector, or from the MediaSpace card via a custom bus.
  • The VideoLogic video card. This was a standard VESA local bus video card that connected to the DVA-4000 through the feature connector.
