My notebook (AMS Tech Rodéo 3072 ECX) has a thing called "ZV port", which apparently is somehow internally connected to the C&T 65555 video chip, and supports things like MPEG decoders, live video input, video capture, etc. According to http://www.pc-card.com/papers/zv.htm, ZV (Zoomed Video) is a dedicated bus, or a connection between a PC-card and host system that allows the card to write video data directly into the VGA frame buffer. Now all this sounds real good, and complete documentation on the 65555 chip is available from C&T's web site: http://www.chips.com/design/graphics/mobilegraphics/datashts/ However, I have been so far unable to find a CCD camera that can be plugged into the ZV port on my notebook, and the responses I got from AMS Tech were completely useless - the bottom line was "we have no idea what you're talking about, get a USB camera like everyone else". Moreover, the 65555 datasheet is very clear - I think if I had a camera connected to the port, I could write a device driver for it - that is, provided such a thing is possible in the first place. Bearing the aforesaid in mind, I have several questions: 1) Can the ZV port on my notebook really be used for video capture, or is it one of those things that was designed to be used in many different ways in the future, but as of yet nothing? 2) If this is indeed possible, is there such a thing as "ZV camera" - or does it have to be used in conjunction with a PC card? 3) If a PC Card is needed, how do all these things (PC Card, ZV port, camera) get connected? (Or is there supposed to be some internal connection between the PCMCIA/Cardbus PCI bridge and the ZV port in order to identify the special "ZV" type of PC Cards?) I've heard that some Toshiba notebooks also have ZV ports - anyone out there have any ZV experience?
