DELTACAST FLEX Enables Scalable Pro AV Video Connectivity

In professional AV, rapid gains in computing power are driving demand for greater video-interface density, flexibility and scalability. Traditional single PCI Express card designs are often constrained by physical space and fixed I/O, limiting their ability to handle complex multichannel signal processing. DELTACAST’s FLEX solution is a modular connectivity architecture designed to address those constraints.

FLEX architecture core logic

FLEX is not a single capture card but a modular connection system. Its core architecture consists of two parts: a PCI Express gateway card, the DELTA-GWY, and video I/O modules connected through dedicated cables. The split design gives systems a high degree of flexibility, allowing users to deploy video I/O modules as floating devices or integrate them into a 19-inch FLEX rack for more efficient use of space.

Gateway card and modular configuration

The DELTA-GWY gateway card serves as the hub of the system. Four models are currently available, distinguished primarily by port count (4 or 8) and the number of PCIe lanes (8 or 16). Compatible FLEX modules fall into two categories, input/capture and output/playback, covering mainstream interfaces including 12G-SDI, DisplayPort and HDMI.

Function type	Typical module models
Input/capture	FLEX-12G 10, FLEX-DP 10, FLEX-HMI 10
Output/playback	FLEX-12G 01, FLEX-DP 01, FLEX-HMI 01

Each FLEX module can independently manage one or more video channels, and all modules are integrated within the unified VideoMaster SDK, simplifying development and integration.

Synchronization and application scenarios

To address timing issues common in high-density signal processing, FLEX-12G modules support an analog Genlock reference input. With DELTACAST’s frame-accurate synchronization capability, the system can ensure that connected output modules maintain precise frequency and phase alignment. That is critical for applications with strict timing requirements, such as multi-screen tiling and broadcast-grade playout.

With this architecture, Pro AV integrators can switch flexibly among SDI, DisplayPort and HDMI to build highly customized video processing workflows.

Frequently Asked Questions

Can FLEX modules mix different interface types?

Yes. The advantage of the FLEX architecture is its flexibility. Users can configure different types of input or output modules under the same gateway card, such as SDI and DisplayPort modules, enabling mixed processing of different interface standards.

How is the required DELTA-GWY gateway specification determined?

Selection depends mainly on the total number of video channels required and PCIe bandwidth needs. The planned number of I/O modules (4 or 8 ports) and data throughput requirements should be matched against the published model specifications.

What mechanical installation options are available for the FLEX system?

FLEX modules are available in several formats, including use as floating devices, internal components installed in custom computer chassis, and integration into standard 19-inch FLEX rack units to suit different industrial and machine-room environments.
