Epiphan VGA2USB LR

Descripción

Epiphan’s VGA2USB LR™ is a frame grabber capture device that acquires frames with up to 1280×1024 pixel resolution in a 24-bit palette. VGA2USB LR can achieve 1280×1024 lossless compression with up to 51 fps, depending on the content being captured.

VGA2USB LR’s internal hardware comes with 16MB RAM on board, an advanced VGA ADC and a custom Epiphan FPGA engine and that performs lossless compression on board, thus improving USB bus bandwidth utilization, throughput, and FPS

Radar, ultrasound, navigational, security, and microscope imagery is best captured with the VGA2USB LR, as long as the source resolution is kept below 1280 x 1024. The VGA2USB LR is also excellent for capturing from sources with significant movement from frame to frame.

Capture high quality video at up to 1280×1024
Progressive scan, 100% lossless compression
Sources power from USB port, no external power supply required
Often used in medical, education, and training capture applications
Interfaces to multiple 3rd party applications compatible with DirectShow on Windows, QuickTime on Mac OS X and V4L (Video4Linux) on Linux

Interface Supports USB 2.0 and USB 1.1 buses. Performance of the VGA2USB LR device will be significantly downgraded, however, when connected to a USB 1.1 bus.
