The VisionAV/B DVI/HDMI Capture Card from DATAPATH is a four lane PCI Express capture card providing up to 800MB/s bandwidth from the capture engine. The VisionAV/B has up to 256MB buffer memory, enabling triple buffering for all video modes for tear free play back. It can also capture digital video for progressive and interlaced modes up to 4096 x 4096 resolutions to a maximum of 165 MHz pixel clock for DVI and 170 MHz for Analog RGB. The card provides HDMI audio capture and streaming from DVI Channel. The VisionAV/B comes with a full-height bracket, a half-height bracket, a DVI/VGA adapter, a DVI/Component adapter, and a DVI/HDMI adapter.
The Vision cards provide high performance DMA to system memory or direct to graphics memory with scatter gather, allowing for low latency fast frame rates in all applications. The complete range of Datapath video capture cards are supported by a generic Windows Vision driver and command line interface also supporting DirectShow and RGBEasy SDK. A single Vision device supports up to 16 independent scale factors, color spaces and frame rate clients. The Datapath capture cards have Timestamp support for capture synchronization across inputs, cards and systems. This is for use with edge blending, frame stitching, stereoscopic and many more applications using gen-locked sources.
The VisionAV has two independent video capture channels - one supporting HD capture and a second simultaneously accepting Standard Definition composite video. The High Definition signals are input via a DVI-I connector and can support HDMI, DVI, RGB and analog Component (YPbPr) video formats all at resolutions up to 4096 x 4096 pixels and supports 1080p (1920x1080) at 60 frames per second. The Standard Definition channel accepts composite video on a single RCA connector and can auto-detect between PAL, NTSC and SECAM formats up to 720 x 576 at 16 bit color. The VisionAV captures both video channels simultaneously and triple buffers them into on-board storage, alongside an audio stream that can be selected from the HDMI port. This data can then be processed and copied using DMA transfers to the host system for display, storage or streaming.
The VisionAV is a suitable solution for applications that require the capture of analog or DVI sources in real time. Typical applications include capturing analog or DVI sources from PCs, MACs, industrial/medical equipment, cameras and other video equipment streaming video applications and video wall controllers.
