Introduction – Vi1/SD4+1S
The Vi1/SD4+1S is an ideal solution for applications that require the capture of up to four SD video
sources and a single Component HD/HDMI/RGB/DVI source simultaneously. Typical applications include:
•
Viewing Analog or DVI sources from PCs, MACs, Industrial/medical equipment, cameras and other video
equipment
•
Streaming video applications
•
Video/Data Wall Controllers
The Vi1/SD4+1S is a four channel PCI express video capture card. The card supports PAL, NTSC
and SECAM in both composite and S-Video input formats, supports de-interlaced video capture and
displays at 25/30 frames/sec for real-time video windows.
In addition, the Vi1/SD4+1S is also a single channel PCIe capture card, able to capture:
•
Component HD up to 1080P at 60 frames per second
•
HDMI up to 1080P (
Audio not supported, HDCP not supported
)
•
DVI up to 1920 x 1200
•
RGB/VGA up to 2048 x 1536
The data is stored in two 32MB frame buffers on the card in real time. The data is transferred using PCI bus
master DMA with scatter gather. The data can be transferred to system memory, to off-screen
memory on a Datapath graphics card or via Direct 3D to third party graphics cards.
Windows Media Encoder® may also be used to stream video across a network or save the video to disk. Win-
dows Media Player® can be used to display the stream or the video that has previously been saved.
