Control Room Video Walls

Capture HD video channels.

Product Feature

  • Use with Radian Video Wall Processor chassis.
  • DVI-I channel one supports HDMI/DVI/RGB/YPbPr video capture.
  • DVI-I channel two has embedded audio capture and streaming.
  • The SD/composite channel supports and auto-detects PAL, NTSC, and SECAM up to 720 x 576 @ 16-bit color.
  • Four-lane PCIe bus provides 1.6 GB/s total capture bandwidth.
  • Direct DMA to graphics memory of third party graphics cards.
  • Low input to output capture latency.

Both high-definition channels support HDMI, DVI, RGB, and analog component (YPbPr) via a DVI-I connector at resolutions up to 1080p (1920 x 1080) at 60 Hz They also support HDMI embedded audio capture and streaming.

All three video channels are captured simultaneously and triple buffered into onboard storage are for tear-free video, alongside an audio stream that can be selected from one of the HDMI or analog audio ports. The data can then be processed and copied using DMA transfers to the host system for display, storage, or streaming.
