Provides simultaneous SD and HD video capture through one channel of DVI-I or HDMI capture and one channel of composite video capture.
The VisionAV is a four lane PCI Express capture card providing up to 800MB/s bandwidth from the capture engine. The VisionAV has up to 256 MB 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 4096x4096 resolutions to a maximum of 165 MHz pixel clock for DVI and 170 MHz for analogue RGB. This card provides HDMI audio capture and streaming from DVI Channel, as well as balanced and unbalanced analogue audio capture.
Vision Range Features
The Vision range provides 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, colour spaces and frame rate clients. The Datapath capture cards have timestamp support for capture synchronisation 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 VisionAV also adds analog audio capture, which can be perfectly synchronised with either video capture channel.
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 720x576 at 16 bit colour.
The VisionAV captures both video channels simultaneously and triple buffers them into onboard storage, alongside an audio stream that can be selected from the HDMI or analogue audio port. This data can then be processed and copied using DMA transfers to the host system for display, storage or streaming.
