Video In Video Out, usually seen as the acronym VIVO (commonly pronounced vee-voh), is a graphics card port which enables some video cards to have bidirectional (input and output) video transfer through a Mini-DIN connector and a specialized splitter cable. VIVO is found predominantly on high end ATI video cards, although a few high end NVIDIA video cards have this port as well. VIVO on these graphics cards typically support composite, S-Video, and Component as outputs and composite and S-Video as inputs. Many other video cards only support component and/or S-Video outputs to compliment VGA or DVI. It should be noted that while the component out signals support high definition resolutions, it does not support the HDCP standard which would be required for official HDTV support as set out by the EICTA. Also, a person using VIVO must have software that can display the input signal. Some practical uses of VIVO include being able to display what's on your computer (including downloaded/recorded tv shows & movies) on a TV and being able to connect a DVD player or video game console to your computer and allow viewing via monitor. Note that VIVO cannot receive radio signals (either from an antenna or cable), and much like tunerless HDTV sets and composite monitors, there must be additional equipment to watch television programs.
