Video-in video-out
Video in video out (usually seen as the acronym VIVO), commonly pronounced ( VEE-voh), is a graphics port which enables some video cards to have bidirectional (input and output) analog video transfer through a mini-DIN connector, usually of the 9-pin variety, and a specialised splitter cable (which can sometimes also transfer analog audio). VIVO was found on high-end ATI and NVIDIA computer video cards, sometimes labeled "TV OUT".
