(Zoomed Video Port) An extension to the PC Card (PCMCIA) standard that provides a high transfer rate for video applications on portable computers. Video data goes directly to the display controller, bypassing the CPU and system bus, allowing full-screen, full-motion playback of digital video. The ZV Port is built into the notebook computer and activated by plugging in an MPEG PC Card that is ZV Port-compliant.The ZV Port equivalent on a desktop computer is the pass-through capability built into the MPEG board. The MPEG board is cabled directly to the monitor and provides a pass through for VGA signals from the graphics card. See VGA pass through.
