The XtremeRGB-Ex1+ is a low-profile PCIe x4 capture card with one DVI-I input. It captures analogue RGB, single-link DVI, and HDMI or component video through an adapter, from one source.

Each frame is triple-buffered on the card, then moved to the host by scatter-gather DMA, into system memory or straight into graphics memory. An on-card processor detects the input mode and follows changes in the source, so a different PC or instrument can be connected without reconfiguring the card.

Inputs

Analogue RGB: Up to 2048 × 1536 at 170 Mpixels/s, with separate H/V sync, composite sync or sync on green. Modes up to a 340MHz pixel clock can be captured using dual-pass sampling.
DVI: Single-link DVI up to 1920 × 1080, or 1920 × 1200 with reduced blanking (165MHz).
HD video: HDMI and component sources through a DVI adapter. HDCP-protected sources cannot be captured.

Outputs

To the computer: Scatter-gather DMA to system memory or directly to graphics memory, from triple-buffered capture memory, so frames arrive without tearing.
Formats: RGB 8-8-8, 5-6-5 and 5-5-5, and YUV 4:2:2.
Scaling and cropping: High-quality downscaling on the card, and up to 16 cropping windows on the channel.

Applications

Medical and industrial equipment: Analogue RGB or DVI from imaging systems, test instruments and process displays.
Computer sources: PCs and Macs shown in a window, recorded or streamed.
Recording and streaming: Works with any DirectShow application, such as VLC.
Video walls: In a VSN wall controller the input appears as a source in VigiControl.
Larger systems: Up to 32 cards in one system.

Installation and software

The card: Low-profile PCIe x4, 68.9 × 167.6mm, fits a x4, x8 or x16 slot. Up to 15W.
Drivers: WDM streaming driver and the Xtreme SDK with DirectShow samples. Check the Windows version with us before ordering for Windows 11 or Linux.
Software: The supplied application detects the source format and shows the input in a window, which can be resized, moved or made full screen.

Range and alternatives

XtremeRGB-Ex2+ has two DVI/RGB channels. XtremeRGB-Ex4+ adds four SD camera inputs to one DVI/RGB channel.
