ZV Port Custom Interface
The ZV (Zoomed Video) Port is a single source, point-to-point uni-directional video
bus between a PC Card socket and a VGA controller. The ZV Port complies with
CCIR601 timing to allow NTSC decoders to deliver real-time digital video straight
into the VGA frame buffer from a PC Card. The ZV Port also allows an industry
standard mechanism for transferring digital audio PCM data to a low cost DAC for
conversion to an analog signal.
In this notebook, only the bottom PC Card slot is ZV capable.
