PRODUCT OVERVIEW

Product Overview

Four-Channel Mixed-Interface Video and Audio Capture

The card integrates two HDMI 1.4 and two 3G-SDI inputs with YUY2 4:2:2 output, hardware deinterlacing, automatic format detection and multiple output streams at different resolutions. Standard DirectShow, DirectSound and V4L2 interfaces simplify software integration and custom development.

Two HDMI and two SDI connectors operate as four independent video inputs
HDMI and SDI input/capture formats up to 1080p60
Four embedded-audio inputs plus one 3.5 mm line-level input
No HDMI or SDI video loop-through outputs
