PROFESSIONAL USB VIDEO CAPTURE
Single-Channel HDMI / 3G-SDI USB 3.0 A/V Capture Box
An external capture solution for streaming, recording, medical imaging, machine vision, and system integration. One video channel accepts either HDMI or 3G-SDI and supports input and capture resolutions up to 1080p60. Audio can be captured from the HDMI/SDI embedded stream or Line In, while a separate Line Out is provided. USB 3.0 connectivity and class-compliant UVC/UAC operation simplify deployment across mainstream systems and applications.

KEY ADVANTAGES
Flexible signal connectivity and efficient USB capture
HDMI / SDI ConnectivitySelect HDMI 1.4 or 3G-SDI on the single capture channel to connect consumer, professional, medical, or industrial sources.
Up to 1080p60Input and capture support resolutions up to 1080p60 for smooth preview, recording, and live production.
Flexible Audio PathsCapture HDMI/SDI embedded audio or an independent Line In source, with a separate Line Out for audio output.
UVC / UAC Plug and PlayClass-compliant USB video and audio operation enables use with compatible software without a proprietary driver.
On-Device ProcessingAutomatic input-format detection, output scaling, and hardware deinterlacing reduce host-side processing demand.
Cross-Platform and SDKSupports Windows, Linux, and macOS, plus standard APIs and an SDK for secondary development.
EXTERNAL USB CAPTURE
Compact HDMI / 3G-SDI A/V capture box
Single selectable input · USB bus powered · No video loop-through
The aluminum enclosure suits desktop, mobile, and embedded integration. SDI IN and HDMI IN are located on the input panel; the opposite panel provides Line In, Audio Out, USB 3.0, and status indicators.
1 × HDMI or 1 × 3G-SDI video input, selectable on one channel
Embedded audio or Line In capture, plus 1 × Line Out
USB 3.0 Type-B host interface, backward-compatible with USB 2.0
98 × 70 × 24 mm enclosure and power consumption up to 2 W
VIDEO AND AUDIO INPUTS
One selectable video channel with flexible audio routing
HDMI and SDI are alternative inputs for the same video channel, not two simultaneous capture channels. No video loop-through is provided. Audio may be captured from the embedded stream or from Line In.
HDMI 1.4 InputConnect cameras, media players, microscopes, or other HDMI sources and capture embedded audio with video.
3G-SDI InputThe BNC input suits professional cameras, studios, medical systems, industrial installations, and longer cable runs.
Line In / Line OutUse Line In for an independent audio source and Line Out for audio output or monitoring. Standard sampling is 48 kHz / 16-bit.

Specification note: HDMI and SDI share one capture channel and must be used alternatively; no video loop-through is provided. Available resolutions, frame rates, and formats in USB 2.0 mode depend on link bandwidth and host configuration. HDCP, operating-system, software, and SDK compatibility may vary with the source, content-protection policy, and software version. Refer to the formal specification and final project confirmation.
