Zoomed video port
In computing, a zoomed video port (often simply ZV port) is a unidirectional video bus allowing a device in a PC card slot to transfer video data directly into a VGA frame buffer, so as to allow laptops to display real-time video. The standard was created by the PCMCIA to allow devices such as TV tuners, video inputs and MPEG coprocessors to fit into a PC card form factor and provide a cheap solution for both the laptop manufacturer and consumer.
The ZV port was invented as an alternative to such methods as the VAFC (VESA Advanced Feature Connector).
