Peryferia Video: VisionRGB-E1S Video Capture

VisionRGB-E1S Video Capture

Producent: Data Path

The VisionRGB-E1S has a single capture channel supporting up to 1920x1080 DVI or 2048x1536 Analog resolution.

The VisionRGB-E1S 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-E1S transfers the data directly to the graphics card thereby increasing performance.  The VisionRGB-E1S sends the relevant portions of each captured image to each display channel and instructs each channel to use its graphics engine to render the data. This fully utilises the hardware and dramatically increases performance.
