What is Zoomed Video (ZV) port?
Rating:
The Zoomed Video port (ZV port) is a technology that supports the delivery of full-screen motion video and multimedia to laptops. It is a direct connection between the PC card slot and VGA controller. It allows special software and the PC Card known as a ZV Port Card to provide a separate dedicated bus from continuously arriving video signals directly to the display controller. Therefore, the video signals are not handled by the main bus or the central processing unit. With this technology, video signals are sent in compressed files using the MPEG standard. The ZV Port Card decompresses the files and sends the data directly to the video frame buffer that is managed by the display controller.
