The XtremeRGB-Ex4+ is a PCIe x4 capture card with five channels: one DVI or analogue RGB input, and four standard-definition inputs for composite or S-Video cameras. All five capture at the same time.

Each frame is triple-buffered on the card, then moved to the host by scatter-gather DMA at up to 650 MB/s, into system memory or straight into graphics memory. An on-card processor detects the input mode and follows changes in the source, so a PC or camera can be changed without reconfiguring the card.

Inputs

DVI: Single-link DVI up to 1920 × 1200, plus custom modes (165MHz).
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.
HD video: 1080p, 1080i, 720p, 576p/i and 480p/i through the DVI-to-component or DVI-to-HDMI adapter. HDCP-protected sources cannot be captured.
SD video: Four PAL, NTSC or SECAM inputs, composite or S-Video, up to 720 × 576, on one D-type connector.

Outputs

To the computer: Up to 650 MB/s across PCIe x4, from 64MB of 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: High-quality downscaling on the card.
Frame rate: Matches the source, as long as the 650 MB/s total is not exceeded.

Applications

Control rooms with analogue cameras: An operator PC, map or process display on the DVI/RGB input, with up to four analogue CCTV cameras on the SD inputs, all from one slot of a wall controller or display PC.
Medical and industrial equipment: Analogue RGB or DVI from imaging systems, test instruments and process displays, captured alongside composite cameras on the same card.
Navigation and vessel systems: Radar or chart displays on the RGB/DVI input, with deck or engine-room cameras on the SD inputs.
Recording and streaming: Each channel can be recorded or streamed with any DirectShow application, such as VLC, StreamPix or VirtualDub.
Larger systems: Up to 32 cards in one system: 128 SD channels and 32 DVI/RGB channels.

Installation and software

The card: PCIe x4, 110 × 204mm, fits a x4, x8 or x16 slot. Up to 15W.
Pack options: XtremeRGB-Ex4+/1 is the card only. XtremeRGB-Ex4+/2 adds the SD breakout cable and DVI-to-VGA, DVI-to-HDMI and DVI-to-component adapters.
Drivers: WDM streaming driver and the Xtreme SDK. The datasheet lists Windows 7, 8.1, 10 and Windows Server 2008; ask us before ordering for Windows 11 or Linux.
Software: The supplied application detects the source format and shows each input in a window. In a VSN wall controller, every channel appears as a source in VigiControl.

Range and alternatives

XtremeRGB-Ex2+ has two DVI/HD/RGB channels and no SD inputs. XtremeRGB-Ex8 has eight SD channels. XtremeRGB-Ex1+ is the single-channel card.

For HDMI 2.0 and 4K sources, see XtremeDV-UHD2 or XtremeDV-HD4+.
