Videum Duo Xpress is part of Winnovs new line of super-fast, super-powerful video capture cards built on the PCI Express architecture. This two channel audio/ video capture card is essentially two AV capture cards in one. Simultaneously, you can capture two different AV source pairs or capture the same sources twice. There are many cases where this is desirable. For IPTV applications, you may want one system to archive and/or broadcast two different videos in the same system. Also, you may want to broadcast the same video with two different qualities. It fits into any PCI Express slot, regardless of lanes.
