Datapath: VisionRGB-E2S Capture Card
Key Features
- High performance DMA to system memory or direct to graphics memory with scatter gather
- On board processor for real time mode and sink detection
- Dynamic input source selection
- Administrator mode
- HD capture for each channel up to 1080p at 60 fps, HDMI capture up to 1080p and DVI up to 1920x1200
The VisionRGB-E2S, a stand alone PCI Express x4 plug in capture card, delivers extreme performance with 650MB/s transfer bus bandwidth providing a further improvement to the 480MB/s of the VisionRGB-E2. This video capture has two complete capture channels supporting up to 1920x1200 DVI or 2048x1536 Analog resolution.
The VisionRGB-E2S captures the Analog/DVI data and triple buffers it into onboard storage. This data is then copied using DMA to the host system for display, storage or streaming.
When a Datapath graphics card is used, the VisionRGB-E2S capture card transfers the data directly to the graphics card thereby increasing performance. The VisionRGB-E2S capture card sends the relevant portions of each channel to use its graphics engine to render the data. This fully utilises the hardware and dramatically increases performance.
When the RGB/DVI data is displayed on a non Datapath graphics card, the VisionRGB-E2S sends the data to system memory or direct to the graphics card, dependant on the software used for display.
The VisionRGB-E2S capture card is an ideal solution for applications require the capture of Analog or DVI sources in real time. Typical applications include:
- Viewing Analog or DVI sources from PCs, MACs, Industrial or medical equipment, cameras and other video equipment
- Streaming video applications
- Video wall controllers
For streaming applications, the VisionRGB-E2S can be used with Windows Media Encoder to compress and stream captures video. To replay the video, use Windows Media Player.
Any application compatible with Windows Direct-Show technology can use the VisionRGB-E2S video capture card due to its built in WDM support.
