Yuan SC550N1 MC HDV Mini PCIe HDMI and DVI Video Capture Card with 1080p60 Input

Equipment with a DVI or component video output, such as an instrument or an older computer, still needs a way into a modern embedded host. The SC550N1 MC HDV is Yuan’s Mini PCIe HDMI and DVI video capture card, with DVI-I and YPbPr inputs alongside HDMI, so one small card takes digital or analogue component signals.

The HDMI, DVI-I and YPbPr inputs come through an on-board wafer connection and act as one capture channel. Digital video is captured at up to 1920 x 1080p at 60/50 fps, while 1920 x 1200 signals at 60/50 fps are taken in and captured at 30/25 fps, with PC modes down to 640 x 480 and more through the SDK. Capture and preview formats are RGB24 and RGB32 at 4:4:4, YUY2 at 4:2:2 and YV12 or NV12 at 4:2:0, all 8-bit, so host software receives frames in the layout it already expects. Cropping, scaling, deinterlacing and automatic signal detection run on the card rather than in host code. YPbPr covers 1080p and 1080i at 60/50 fps, 720p and standard definition. Audio is HDMI embedded, with a pair of analogue audio connections through the wafer, sampled as 16-bit stereo at 32 to 48 kHz.

It is a full-size Mini PCIe (Minicard) card on a PCIe x1 link, with no on-board encoder. For software, Yuan provides Windows and Linux SDKs and lists vMix, OBS, Zoom, Skype, Teams and Webex among compatible applications through DirectShow and V4L2. The SC550N1 MC AIO trades DVI-I and YPbPr for HDMI and SDI, and the SC5A0N1 MC HDV keeps these inputs and adds H.26X hardware encoding.

Yuan lists support for Windows 7, 8, 8.1 and 10, Linux kernel 2.6.14 or later in 32-bit and 64-bit builds, Linux on ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX. The board measures 30 x 50.95 mm, with its video and audio brought out on a breakout cable from the wafer. Yuan lists multi-device and multi-instance support.
