FLEX is DELTACAST'S revolutionary solution answering the questions of flexibility, high density, scalability and redefines video interfacing.

With FLEX, your appliance will convey a versatile high density connectivity that surpass any solution on the market based on a single PCI Express card.

Do you need more than 8 SDI input and outputs channels, more than 2 DisplayPort channels, more than 2 HDMI channels on a single low-profile PCIe slot?

Does your uses cases requires to support a mix of these types of interface on a single card? Does this mix change from deployment to deployment of the same machine?

If so, the FLEX solution brings you a unique and future-proof answer.


FLEX Architecture

The FLEX solution is a combination of a PCI Express gateway cardvideo I/O modules and cables. 

DELTA-GWY is the gateway card you plug in a PCI Express slot of your appliance.


Two models of DELTA-GWY are available;

  • DELTA-GWY 316-8 featuring eight ports.
  • DELTA-GWY 316-4 featuring four ports.


Each of the ports available on the DELTA-GWY card allows a connection to one of the numerous input and output modules available;

  • Input / Capture:

- FLEX-3G 40 4 inputs 3G-SDI module
- FLEX-DP 10 Single-input DisplayPort 1.2 module
- FLEX-HMI 10 Single-input HDMI 2.0 module

  • Output / Playout:

- FLEX-3G 04 4 outputs 3G-SDI module
- FLEX-DP 01 Single-output DisplayPort 1.2 module (available soon)
- FLEX-HMI 01 Single-output HDMI 2.0 module (available soon)

Each module is an independent device that manages one or several video channels.

Other modules are in development and will complete the family very soon (contact us for further details).

As with all its other products, DELTACAST has taken care to integrate FLEX into its unified VideoMaster SDK, so each module is just seen like a normal PCIe card plugged into your server.

By integrating FLEX in your appliance, you also have access to all others cards available in the DELTACAST product catalog.

FLEX Versatility

Each FLEX modules connect with an individual cable to ports of the DELTA-GWY gateway card.

In order to offer maximum flexibility in the design of your appliance's connectivity, each FLEX module is available in different mechanical formats.

Therefore, the video input and output ports can be assembled in the most appropriate way according the form factor of your solution.

They are available in different mechanical options to offer maximum flexibility in your final product  assembly :                                                                                                              

  • As an integrated module, the module comes as a little box that can be either floating or attached anywhere around your server thanks to different mounting holes.
  • As an internal component, the module only includes a top cover which is actually its passive cooling solution. In this form, the module is generally mounted inside your product enclosure.
  • Several modules can be assembled together in a 19'' rack unit (1U or 2U) for fixed installations.


An historical evolution


Continuously increasing computer processing power allows handling more and more sources in parallel, with larger and larger resolutions. The maximum amount of signals a server can handle is so high that it is generally limited by the amount of capture channels that mechanically fit the computer chassis, rather than by the available internal resources.

In 2012, DELTACAST revolutionized the world of video interface cards, allowing up to 8 channels on a low-profile PCI Express card.

This compact eight-channel configuration quickly became a standard.

Of course, CPU and GPU processing power continues evolving and the limiting factor is again the amount of cards you can plug in the computer and the size of the connectors on the mechanical bracket.

Another trend in the market is to take the maximum profit from a hardware investment, by using it for multiple purposes. A server is a completely generic processing machine, and dedicating it to a single use case, potentially not being used 24/7, is not giving the best return on investment.

Using the same machine in different contexts often requires a great flexibility in terms of video interface technologies, especially in the Pro AV market: DisplayPort and HDMI sources are more prevalent in use cases like corporate events, education and installation, while SDI is often used as soon as you have got to connect your server to a video production facility.

DELTACAST closely looked at these market evolutions and created the FLEX family of products.
