Datapath VisionAV VisionAV/B

Overview

The VisionAV is a x4 lane PCI Express capture card providing up to 800 MB/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 4096 x 4096 resolutions to a maximum of 165 MHz pixel clock for DVI and 170 MHz for Analog RGB. This card provides HDMI audio capture and streaming from DVI channel, as well as balanced and unbalanced analog audio capture.¦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, color 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 synchronized with either video capture channel.¦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 Analog audio port. This data can then be processed and copied using DMA transfers to the host system for display, storage or streaming.
