INTRODUCTION
The BG-CSA USB 3.1 Gen 1 3G-SDI Capture Device with Scaler and Audio provides a professional
way to capture 3G/HD/SD-SDI signals. It utilizes the USB 3.1 Gen 1 (USB 3.0) interface to achieve high-
speed transmission. With this device users can capture 3G/HD/SD-SDI signals. Additionally, BG-CSA can
capture and display original uncompressed 3G/HD/SD-SDI with realistic color rendition. BG-CSA also uses
large volume image buffer technology which effectively avoids video tearing. The high sampling rate and
high sampling accuracy assure images with high sharpness, rich details, and fewer color edges.
