Dedicated decoding card

  • Dual RJ45 Ethernet ports
  • On-board SQX decoding engine
  • 800 Mb/s from each Ethernet ‘input’

Decode multiple streams simultaneously:

  • Up to three 4096x2160p at 30 fps
  • Six 1920x1080p at 60 fps / 12 at 30 fps
  • 50+D1 resolution streams @ 30fps
  • Maximum will depend on H.264 profiles and levels of incoming media


Xtreme-ActiveSQX – Dedicated decoding card

Professional AV solutions require video to be received from a great many different sources and locations. The ability to receive and display video directly from online resources such as CCTV networks and remote desktop applications. Combining them with local inputs has become an everyday part of fully functional video wall display.

The Xtreme-ActiveSQX PCIe plug in card is a powerful addition to systems that require a scalable hardware based decoding solution.

The Xtreme-ActiveSQX is a half length PCI-Express plug in card with two Gigabit Ethernet input nodes supporting real time decode of multiple IP streams. Using the Xtreme-ActiveSQX decoding technology provides the user seamless integration of IP video to a EMS Wall Controller.


Each Xtreme-ActiveSQX card can capture a bandwidth equivalent to twelve 1920×1080 @30Hz streams on to any wall controller that uses EMS graphics cards. The number of streams the Xtreme-ActiveSQX provides depends on a number of factors such as the decoder profile used. Each card uses a single PCIe slot, is passively cooled and can easily be added to a system already using EMS technology without the need to change existing configuration or front end software.

This transparent software model enables the number of supported IP streams to be scaled up quickly according to the user requirements. Xtreme-ActiveSQX also automatically balances the total decoding workload
across all Xtreme-ActiveSQX cards in the system, allowing thermal power consumption to be distributed more efficiently.

SQX technology has been designed to work alongside the EMS Xtreme range of capture cards supporting a mixture of local and remote capture feeds on the same display. IP Streams are displayed on the video wall in the same way as captured video sources. SQX functionality is compatible with many existing window features.
